50MHz, 800V/µs Op Amps

DESCRIPTIO

The LT1361/LT1362 are dual and quad low power high
speed operational amplifiers with outstanding AC and DC
performance. The amplifiers feature much lower supply
current and higher slew rate than devices with comparable
bandwidth. 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
500Ω load to ±13V with ±15V supplies and a 150Ω load to
±3.2V on ±5V supplies. The amplifiers are stable with any
capacitive load making them useful in buffer or cable
driving applications.

The LT1361/LT1362 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 LT1361/LT1362 see the LT1360 data sheet.
For higher bandwidth devices with higher supply currents
see the LT1363 through LT1365 data sheets. For lower
supply current amplifiers see the LT1354 to LT1359 data
sheets. Singles, duals, and quads of each amplifier are
available.
