Datasheet HA-5170 Datasheet (Intersil Corporation)

HA-5170

Data Sheet September 1998 File Number 2912.3

8MHz, Precision, JFET Input
Operational Amplifier

The Intersil HA-5170 is a precision, JFET input, operational
amplifier which featureslownoise,low offset voltageandlow
offset voltage drift. Constructed using FET/Bipolar
technology, the Intersil Dielectric Isolation (DI) process, and
laser trimming this amplifier offers low input bias and offset
currents. This operational amplifier design also completely
eliminates the troublesome errors due to warm-up drift.

Complementing these excellent input characteristics are
dynamic performance characteristics never before available
from precision operationalamplifiers.An8V/µsslewrateand
8MHz bandwidth allow the designer to extend precision
instrumentation applications in both speed and bandwidth.
These characteristics make the HA-5170 well suited for
precision integrator amplifier designs.

The superior input characteristics also make the HA-5170
ideally suited for transducer signal amplifiers, precision
voltagefollowers and precision data acquisitionsystems.For
application assistance, please refer to Application Note
AN540 addressing specifically this device.
