LT1359 - Quad 25MHz, 600V/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 Ohms load to ±12.5V with ±15V supplies and a 150 Ohms 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.
