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
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
500load 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 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
lower supply current amplifiers see the LT1354 and LT1355/
LT1356 data sheets. Singles, duals, and quads of each
amplifier are available.
