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 opera tion 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 industrial (–40°C to +125°C) temperature range. 3 V operation is specified over the 0°C to 125°C temperature range.
