µs Op Amps

The LT1358/LT1359 are dual and quad low power high

speed operational amplifiers with outstanding AC and DC

performance. The amplifiers feature much lower supply

current and higher slew rate than devices with comparable

bandwidth. The circuit topology is a voltage feedback

amplifier with matched high impedance inputs and the

slewing performance of a current feedback amplifier. The

high slew rate and single stage design provide excellent

settling characteristics which make the circuit an ideal

choice for data acquisition systems. Each output drives a

500

Ω load to ±12.5V with ±15V supplies and a 150Ω load

to

±3V on ±5V supplies. The amplifiers are stable with any

capacitive load making them useful in buffer applications.

The LT1358/LT1359 are members of a family of fast, high

performance amplifiers using this unique topology and

employing Linear Technology Corporation’s advanced

bipolar complementary processing. For a single amplifier

version of the LT1358/LT1359 see the LT1357 data sheet.

For higher bandwidth devices with higher supply currents

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.
