Drives Capacitive Loads
The LT1201/LT1202 are dual and quad low power, high
speed operational amplifiers with excellent DC perfor-
mance. The LT1201/LT1202 feature much lower supply
current than devices with comparable bandwidth and slew
rate. Each amplifier is a single gain stage with outstanding
settling characteristics. The fast settling time makes the
circuit an ideal choice for data acquisition systems. Each
output is capable of driving a 2kΩ load to
±12V
with
±15V
supplies and a 500Ω load to
±3V
on
±5V
supplies. The
amplifiers are also capable of driving large capacitive
loads which make them useful in buffer or cable driver
applications.
The LT1201/LT1202 are members of a family of fast, high
performance amplifiers that employ Linear Technology
Corporation’s advanced bipolar complementary
processing.

Note 1:
A heat sink may be required to keep the junction temperature
below absolute maximum when the output is shorted indefinitely.
Note 2:
Input offset voltage is pulse tested with automated test equipment
and is exclusive of warm-up drift.
Note 3:
Slew rate is measured in a gain of –2. For
±15V
supplies measure
between
±10V
on the output with
±6V
on the input. For
±5V
supplies
measure between
±2V
on the output with
±1.75V
on the input.
Note 4:
Full power bandwidth is calculated from the slew rate
measurement: FPBW = SR/2πV
P
.
Note 5:
Commercial grade parts are designed to operate over the
temperature range of –40°C to 85°C but are neither tested nor guaranteed
beyond 0°C to 70°C. Industrial grade parts specified and tested over
–40°C to 85°C are available on special request. Consult factory.
