GENERAL DESCRIPTION
The OP196 family of CBCMOS operational amplifiers features micropower operation and rail-to-rail input and output ranges.
The extremely low power requirements and guaranteed operation from 3 V to 12 V make these amplifiers perfectly suited to monitor battery usage and to control battery charging. Their dynamic performance, including 26 nV/√Hz voltage noise density, recommends them for battery-powered audio applications. Capacitive loads to 200 pF are handled without oscillation.
The OP196/OP296/OP496 are specified over the HOT extended industrial (–40°C to +125°C) temperature range. 3 V operation is specified over the 0°C to 125°C temperature range.
The single OP196 and the dual OP296 are available in 8-lead SO-8 surface mount packages. The dual OP296 is available in 8-lead PDIP. The quad OP496 is available in 14-lead plastic DIP and narrow SO-14 surface-mount packages.

*Not for new design, obsolete April 2002.
CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the OP196/OP296/OP496 feature proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality.
WARNING!
