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 150

Ω load to ±7.5V with

±15Vsuppliesandto±3.4Von±5Vsupplies.Theamplifier

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.
