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 applica-
