70MHz, 1000V/µs Op Amp

The LT1363 is a high speed, very high slew rate operational amplifier with excellent DC performance. The LT1363 features reduced 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 150Ω load to ±7.5V with ±15V supplies and to ±3.4V on ±5V supplies. The amplifier is also capable of driving any capacitive load which makes it useful in buffer or cable driver applications.

The LT1363 is a member of a family of fast, high performance amplifiers using this unique topology and employing advanced bipolar complementary processing. For dual and quad amplifier versions of the LT1363 see the LT1364/1365 data sheet. For 50MHz amplifiers with 4mA of supply current per amplifier see the LT1360 and LT1361/1362 data sheets. For lower supply current amplifiers with bandwidths of 12MHz and 25MHz see the LT1354 through LT1359 data sheets. Singles, duals, and quads of each amplifier are available.
