OP296

a FEATURES Rail-to-Rail Input and Output Swing Low Power: 60 ␮A/Amplifier Gain Bandwidth Product: 450 kHz Single-Supply Operation: 3 V to 12 V Low Offset Voltage: 300 ␮V max High Open-Loop Gain: 500 V/mV Unity-Gain Stable No Phase Reversal APPLICATIONS Battery Monitoring Sensor Conditioners Portable Power Supply Control Portable Instrumentation 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 extended industrial (–40°C to +125°C) temperature range. 3 V operation is specified over the 0...
