The LT
®
1220 is a high speed operational amplifier with
superior DC performance. The LT1220 features reduced
input offset voltage, lower input bias currents and higher
DC gain than devices with comparable bandwidth and slew
rate. The circuit is a single gain stage that includes
proprietary DC gain enhancement circuitry to obtain pre-
cision with high speed. The high gain and fast settling time
make the circuit an ideal choice for data acquisition
systems. The circuit is also capable of driving large
capacitive loads which makes it useful in buffer or cable
driver applications.
The LT1220 is a member of a family of fast, high perfor-
mance amplifiers that employ Linear Technology
Corporation’s advanced complementary bipolar process-
ing. For applications with gains of 4 or greater the LT1221
can be used, and for gains of 10 or greater the LT1222 can
be used for increased bandwidth.

of a device may be impaired.
Note 2: A heat sink may be required when the output is shorted indefinitely.
Note 3: Commercial parts are designed to operate over –40°C to 85°C, but
are not 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.
