The LT
1354 is a low power, high speed, high slew rate
operational amplifier with outstanding AC and DC perfor-
mance. The LT1354 has much lower supply current, lower
input offset voltage, lower input bias current, and higher
DC gain than devices with comparable bandwidth. The
circuit topology is a voltage feedback amplifier with the
slewing characteristics of a current feedback amplifier.
The amplifier is a single gain stage with outstanding
settling characteristics which makes the circuit an ideal
choice for data acquisition systems. The output drives a
500
load to
12V with
15V supplies and a 150
load
to
2.5V on
5V supplies. The amplifier is also stable with
any capacitive load which makes it useful in buffer or cable
driver applications.
The LT1354 is a member of a family of fast, high perfor-
mance amplifiers using this unique topology and employ-
ing Linear Technology Corporation's advanced bipolar
complementary processing. For dual and quad amplifier
versions of the LT1354 see the LT1355/LT1356 data
sheet. For higher bandwidth devices with higher supply
current see the LT1357 through LT1365 data sheets.
Singles, duals, and quads of each amplifier are available.

ELECTRICAL CHARACTERISTICS
The
q
denotes specifications that apply over the full specified temperature
range.
Note 1: Differential inputs of
10V are appropriate for transient operation
only, such as during slewing. Large, sustained differential inputs will
cause excessive power dissipation and may damage the part. See Input
Considerations in the Applications Information section of this data sheet
for more dutails.
Note 2: A heat sink may be required to keep the junction temperature
below absolute maximum when the output is shorted indefinitely.
Note 3: Slew rate is measured between
10V on the output with
6V input
for
15V supplies and
1V on the output with
1.75V input for
5V supplies.
Note 4: Full power bandwidth is calculated from the slew rate
measurement: FPBW = SR/2
V
P
.
Note 5: This parameter is not 100% tested.
Note 6: The LT1354 is designed, characterized and expected to meet these
extended temperature limits, but is not tested at 40
C and at 85
C.
