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 500Ω load to
±13V
with
±15V
supplies and a 150Ω 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.
Note 6:
Full power bandwidth is calculated from the slew rate
measurement: FPBW = SR/2πV
P
.
Note 7:
This parameter is not 100% tested.
Note 8:
The LT1360C is guaranteed functional over the operating
temperature range of –40°C to 85°C.
Note 9:
The LT1360C is guaranteed to meet specified performance from
0°C to 70°C. The LT1360C is designed, characterized and expected to
meet specified performance from – 40°C to 85°C, but is not tested or QA
sampled at these temperatures. For guaranteed I-grade parts, consult the
factory.
