The LT1355/LT1356 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 LT1355/LT1356 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 LT1355/LT1356 see the LT1354 data sheet.

For higher bandwidth devices with higher supply currents

see the LT1357 through LT1365 data sheets. Bandwidths

of 25MHz, 50MHz, and 70MHz are available with 2mA,

4mA, and 6mA of supply current per amplifier. Singles,

duals, and quads of each amplifier are available.
