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
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 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.

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.
Note 5: Full power bandwidth is calculated from the slew rate
measurement: FPBW = (SR)/2
V
P
.
Note 6: This parameter is not 100% tested.
Note 7. The LT1358C/LT1359C are guaranteed functional over the
operating temperature range of 40
C to 85
C.
Note 8: The LT1358C/LT1359C are guaranteed to meet specified
performance from 0
C to 70
C. The LT1358C/LT1359C are designed,
characterized and expected to meet specified performance from 40
C to
85
C, but are not tested or QA sampled at these temperatures. For
guaranteed I-grade parts, consult the factory.
