The LT1355/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
500
load to
12.5V with
15V supplies and a 150
load
to
3V 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.

Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: Differential inputs of
10V are appropriate for transient operation
only, such as during slewing. Large, sustained differential inputs will cause
excessive power dissipation and may damage the part. See Input
Considerations in the Applications Information section of this data sheet
for more details.
Note 3: A heat sink may be required to keep the junction temperature
below absolute maximum when the output is shorted indefinitely.
Note 4: Slew rate is measured between
10V on the output with
6V input
for
15V supplies and
1V on the output with
1.75V input for
5V
supplies.
