The LT®1355/LT1356 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 ±12V with ±15V supplies and a 150Ω load to
±2.75V on ±5V supplies. The amplifiers are stable with any
capacitive load making them useful in buffer applications.

The LT1355/LT1356 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 LT1355/LT1356 see the LT1354 data sheet.
For higher bandwidth devices with higher supply currents
see the LT1357 through LT1365 data sheets. Bandwidths
of 25MHz, 50MHz, and 70MHz are available with 2mA,
4mA, and 6mA of supply current per amplifier. Singles,
duals, and quads of each amplifier are available.
