The LT1360 is a high speed, very high slew rate opera-
tional amplifier with excellent DC performance. The LT1360
features reduced supply current, lower input offset volt-
age, lower input bias current and higher DC gain than
devices with comparable bandwidth. The circuit topology
is a voltage feedback amplifier with the slewing character-
istics of a current feedback amplifier. The amplifier is a
single gain stage with outstanding settling characteristics
which makes the circuit an ideal choice for data acquisition
systems. The output drives a 500
load to
13V with
15V
supplies and a 150
load to
3.2V on
5V supplies. The
amplifier is also capable of driving any capacitive load
which makes it useful in buffer or cable driver applications.
The LT1360 is a member of a family of fast, high
performance amplifiers using this unique topology and
employing Linear Technology Corporation's advanced
bipolar complementary processing. For dual and quad
amplifier versions of the LT1360 see the LT1361/LT1362
data sheet. For 70MHz amplifiers with 6mA of supply
current per amplifier see the LT1363 and LT1364/LT1365
data sheets. For lower supply current amplifiers with
bandwidths of 12MHz and 25MHz see the LT1354
through LT1359 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: Input offset voltage is pulse tested and is exclusive of warm-up drift.
Note 5: Slew rate is measured between
10V on the output with
6V input
for
15V supplies and
2V on the output with
1.75V input for
5V supplies.
