DESCRIPTIO
The LT1363 is a high speed, very high slew rate opera-
tional amplifier with excellent DC performance. The LT1363
features reduced supply current, lower input offset volt-
age, lower input bias current and higher DC gain than
devices with comparable bandwidth. The circuit topology
is a voltage feedback amplifier with the slewing character-
istics 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 perfor-
mance 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.
