DESCRIPTION
The DRV134 and DRV135 are differential output
amplifiers that convert a single-ended input to a
balanced output pair. These balanced audio drivers
consist of high performance op amps with on-chip
precision resistors. They are fully specified for high
performance audio applications and have excellent
ac specifications, including low distortion (0.0005%
at 1kHz) and high slew rate (15V/
s).
The on-chip resistors are laser-trimmed for accurate
gain and optimum output common-mode rejection. Wide
output voltage swing and high output drive capability
allow use in a wide variety of demanding applications.
They easily drive the large capacitive loads associated
with long audio cables. Used in combination with the
INA134 or INA137 differential receivers, they offer a
complete solution for transmitting analog audio signals
without degradation.
The DRV134 is available in 8-pin DIP and SOL-16
surface-mount packages. The DRV135 comes in a
space-saving SO-8 surface-mount package. Both are
specified for operation over the extended industrial
temperature range, 40
C to +85
C and operate from
55
C to +125
C.

This integrated circuit can be damaged by ESD. Burr-Brown
recommends that all integrated circuits be handled with ap-
propriate precautions. Failure to observe proper handling and
installation procedures can cause damage.
ESD damage can range from subtle performance degradation
to complete device failure. Precision integrated circuits may
be more susceptible to damage because very small parametric
changes could cause the device not to meet its published
specifications.

APPLICATIONS INFORMATION
The DRV134 (and DRV135 in SO-8 package) converts a
single-ended, ground-referenced input to a floating differ-
ential output with +6dB gain (G = 2). Figure 1 shows the
basic connections required for operation. Decoupling ca-
pacitors placed close to the device pins are strongly recom-
mended in applications with noisy or high impedance power
supplies.
The DRV134 consists of an input inverter driving a cross-
coupled differential output stage with 50
series output
resistors. Characterized by low differential-mode output
impedance (50
) and high common-mode output imped-
ance (1.6k
), the DRV134 is ideal for audio applications.
Normally, +V
O
is connected to +Sense, V
O
is connected to
Sense, and the outputs are taken from these junctions as
shown in Figure 1. For applications with large dc cable
offset errors, a 10
F electrolytic nonpolarized blocking
capacitor at each sense pin is recommended as shown in
Figure 2.

DRV134, 135
Excellent internal design and layout techniques provide low
signal distortion, high output level (+27dBu), and a low
noise floor (98dBu). Laser trimming of thin film resistors
assures excellent output common-mode rejection (OCMR)
and signal balance ratio (SBR). In addition, low dc voltage
offset reduces errors and minimizes load currents.
For best system performance, it is recommended that a high
input-impedance difference amplifier be used as the re-
ceiver. Used with the INA134 (G = 0dB) or the INA137 (G
=
6dB) differential line receivers, the DRV134 forms a
complete solution for driving and receiving audio signals,
replacing input and output coupling transformers commonly
used in professional audio systems (Figure 2). When used
with the INA137 (G = 6dB) overall system gain is unity.
AUDIO PERFORMANCE
The DRV134 was designed for enhanced ac performance.
Very low distortion, low noise, and wide bandwidth provide
superior performance in high quality audio applications.
Laser-trimmed matched resistors provide optimum output
common-mode rejection (typically 68dB), especially when
compared to circuits implemented with op amps and discrete
precision resistors. In addition, high slew rate (15V/
s) and
fast settling time (2.5
s to 0.01%) ensure excellent dynamic
response.
The DRV134 has excellent distortion characteristics. As
shown in the distortion data provided in the typical perfor-
mance curves, THD+Noise is below 0.003% throughout the
audio frequency range under various output conditions. Both
differential and single-ended modes of operation are shown.
In addition, the optional 10
F blocking capacitors used to
minimize V
OCM
errors have virtually no effect on perfor-
mance. Measurements were taken with an Audio Precision
System One (with the internal 80kHz noise filter) using the
THD test circuit shown in Figure 3.
Up to approximately 10kHz, distortion is below the mea-
surement limit of commonly used test equipment. Further-
more, distortion remains relatively constant over the wide
output voltage swing range (approximately 2.5V from the
positive supply and 1.5V from the negative supply). A
special output stage topology yields a design with minimum
distortion variation from lot-to-lot and unit-to-unit. Further-
more, the small and large signal transient response curves
demonstrate the DRV134's stability under load.
OUTPUT COMMON-MODE REJECTION
Output common-mode rejection (OCMR) is defined as the
change in differential output voltage due to a change in
output common-mode voltage. When measuring OCMR,
V
IN
is grounded and a common-mode voltage, V
CM
, is
applied to the output as shown in Figure 4. Ideally no
differential mode signal (V
OD
) should appear. However, a
small mode-conversion effect causes an error signal whose
magnitude is quantified by OCMR.

SIGNAL BALANCE RATIO
Signal balance ratio (SBR) measures the symmetry of the
output signals under loaded conditions.
To measure SBR an
input signal is applied and the outputs are summed as shown
in Figure 5. V
OUT
should be zero since each output ideally
is exactly equal and opposite. However, an error signal
results from any imbalance in the outputs. This error is
quantified by SBR. The impedances of the DRV134's out
put stages are closely matched by laser trimming to mini-
mize SBR errors. In an application, SBR also depends on the
balance of the load network.
SINGLE-ENDED OPERATION
The DRV134 can be operated in single-ended mode without
degrading output drive capability. Single-ended operation
requires that the unused side of the output pair be grounded
(both the V
O
and Sense pins) to a low impedance return path.
Gain remains +6dB. Grounding the negative outputs as
shown in Figure 6 results in a noninverted output signal
(G = +2) while grounding the positive outputs gives an
inverted output signal (G = 2).

For best rejection of line noise and hum differential mode
operation is recommended. However, single-ended perfor-
mance is adequate for many applications. In general single-
ended performance is comparable to differential mode (see
THD+N typical performance curves), but the common-
mode and noise rejection inherent in balanced-pair systems
is lost.
CABLE
The DRV134 is capable of driving large signals into 600
loads over long cables. Low impedance shielded audio
cables such as the standard Belden 8451 or 9452 (or similar)
are recommended, especially in applications where long
cable lengths are required.
THERMAL PERFORMANCE
The DRV134 and DRV135 have robust output drive capa-
bility and excellent performance over temperature. In most
applications there is no significant difference between the
DIP, SOL-16, and SO-8 packages. However, for applica-
tions with extreme temperature and load conditions, the
SOL-16 (DRV134UA) or DIP (DRV134PA) packages are
recommended. Under these conditions, such as loads greater
than 600
or very long cables, performance may be de-
graded in the SO-8 (DRV135UA) package.
LAYOUT CONSIDERATIONS
A driver/receiver balanced-pair (such as the DRV134 and
INA137) rejects the voltage differences between the grounds
at each end of the cable, which can be caused by ground
currents, supply variations, etc. In addition to proper bypass-
ing, the suggestions below should be followed to achieve
optimal OCMR and noise rejection.
The DRV134 input should be driven by a low impedance
source such as an op amp or buffer.
As is the case for any single-ended system, the source's
common should be connected as close as possible to the
DRV134's ground. Any ground offset errors in the source
will degrade system performance.
Symmetry on the outputs should be maintained.
Shielded twisted-pair cable is recommended for all appli-
cations. Physical balance in signal wiring should be main-
tained. Capacitive differences due to varying wire lengths
may result in unequal noise pickup between the pair and
degrade OCMR. Follow industry practices for proper sys-
tem grounding of the cables.
