The LT

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

500

Ω 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

lower supply current amplifiers see the LT1354 and LT1355/

LT1356 data sheets. Singles, duals, and quads of each

amplifier are available.
