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 14-Lead Narrow-Body SO density, recommends them for battery-powered audio applica- tions. Capacitive loads to 200 pF are handled without oscillation.
