FEATURES
DESCRIPTION
The LT®1357 is a high speed, very high slew rate opera-
tional amplifier with outstanding AC and DC performance.
The LT1357 has much lower supply current, lower input
offsetvoltage,lowerinputbiascurrent,andhigherDCgain
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
500Ω load to ±12V with ±15V supplies and a 150Ω
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 LT1357 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 LT1357 see the LT1358/LT1359 data
sheet. For higher bandwidth devices with higher supply
current see the LT1360 through LT1365 data sheets. For
lowersupplycurrentamplifiersseetheLT1354andLT1355/
LT1356 data sheets. Singles, duals, and quads of each
amplifier are available.
