FEATURES
DESCRIPTIO
■
25MHz Gain Bandwidth
The LT1358/LT1359 are dual and quad low power high
speed operational amplifiers with outstanding AC and DC
performance. The amplifiers feature much lower supply
currentandhigherslewratethandeviceswithcomparable
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 ±12.5V with ±15V supplies and a 150Ω load
to ±3V on ±5V supplies. The amplifiers are stable with any
capacitive load making them useful in buffer applications.

The LT1358/LT1359 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 LT1358/LT1359 see the LT1357 data sheet.
For higher bandwidth devices with higher supply currents
see the LT1360 through LT1365 data sheets. For lower
supply current amplifiers see the LT1354 and LT1355/
LT1356 data sheets. Singles, duals, and quads of each
amplifier are available.
