12MHz, 400V/µs Op Amp

DESCRIPTION

®

The LT
operational amplifier with outstanding AC and DC perfor­mance. 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
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 LT1354 is a member of a family of fast, high perfor­mance amplifiers using this unique topology and employ­ing 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.
