The LT1364/LT1365 are dual and quad high speed opera-
tional amplifiers with outstanding AC and DC perfor-
mance. The amplifiers feature much lower supply current
and higher slew rate than devices with comparable band-
width. 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 150Ω load
to
±7.5V
with
±15V
supplies and to
±3.4V
on
±5V
sup-
plies. The amplifiers are stable with any capacitive load
making them useful in buffer or cable driving applications.
The LT1364/LT1365 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 LT1364/LT1365 see the LT1363 data sheet.
For 50MHz devices with 4mA supply currents see the
LT1360 through LT1362 data sheets. For lower supply
current amplifiers see the LT1354 to LT1359 data sheets.
Singles, duals, and quads of each amplifier are available.
