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.

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.

NOTES
1
Long-term offset voltage is guaranteed by a 1,000 hour life test performed on three independent lots at 12 5°C, with an LTPD of 1.3.
2
Offset voltage drift is the average of the 0°C to 25°C delta and the 25°C to 125°C delta.
