CLC5632
Dual, High Output, Programmable Gain Buffer
General Description
The CLC5632 is a dual, low cost, high speed (130MHz)
buffer which features user programmable gains of +2, +1,
and -1V/V. The CLC5632 also has a new output stage that
delivers high output drive current (130mA), but consumes
minimal quiescent supply current (3.0mA/ch) from a single
5V supply. Its current feedback architecture, fabricated in an
advanced complementary bipolar process, maintains consis-
tent performance over a wide range of gains and signal
levels, and has a linear phase response up to one half of the
-3dB frequency.
The CLC5632 offers 0.1dB gain flatness to 30MHz and
differential gain and phase errors of 0.08% and 0.02. These
features are ideal for professional and consumer video ap-
plications.
The CLC5632 offers superior dynamic performance with a
130MHz small-signal bandwidth, 410V/s slew rate and
5.0ns rise/fall times (2V
step
). The combination of low quies-
cent power, high output current drive, and high speed per-
formance make the CLC5632 well suited for many battery
powered personal communication/computing systems. The
ability to drive low impedance, highly capacitive loads,
makes the CLC5632 ideal for single ended cable applica-
tions. It also drives low impedance loads with minimum
distortion. The CLC5632 will drive a 100
load with only
-82/-69dBc second/third harmonic distortion (A
V
= +2,
V
OUT
= 2V
PP
, f = 1MHz). With a 25
load, and the same
conditions, it produces only -71/-73dBc second/third har-
monic distortion. It is also optimized for driving high currents
into single-ended transformers and coils. When driving the
input of high resolution A/D converters, the CLC5632 pro-
vides excellent -86/-96dBc second/third harmonic distortion
(A
V
= +2, V
OUT
= 2V
PP
, f = 1MHz, R
L
= 1k
) and fast
settling time.

Note 1: "Absolute Maximum Ratings" are those values beyond which the safety of the device cannot be guaranteed. They are not meant to imply that the devices
should be operated at these limits. The table of "Electrical Characteristics" specifies conditions of device operation.
Note 2: Min/max ratings are based on product characterization and simulation. Individual parameters are tested as noted. Outgoing quality levels are determined
from tested parameters.
Note 3: AJ-level: spec. is 100% tested at +25C.
