GENERAL DESCRIPTION

guaranteed to operate from 3 V to 30 V (or ±1.5 V to ±15 V)

and at very high temperatures.

require both ac and precision dc performance. The combination

useful in a wide variety of applications, including filters and

interfacing with a variety of sensors.

This dual-channel op amp is offered in an 8-lead SOIC plastic

package with an operating temperature range of −40°C to +175°C.

It is also available in an 8-lead ceramic flat package (flatpack)

with an operating temperature range of −40°C to +210°C. Both

packages are designed for robustness at extreme temperatures

and are qualified for 1000 hours of operation at the maximum

temperature rating.
