The LT1363 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 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.

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.
