The extremely low power requirements and guaranteed operation from 3 V to 30 V (±1.5 V to ±15 V) make these amplifiers perfectly suited to monitor battery usage and to control battery charging. Their dynamic performance, including 27 nV/√Hz voltage noise density, recommends them for battery-powered audio applications. The amplifier can drive capacitive loads up to 200 pF without oscillation. The ADA4096 has overvoltage protection inputs that allow the voltage input to exceed 32V above and below the supply rails without damage, glitching, or phase reversal, making the device ideal for robust industrial applications. The ADA4096 are specified over the extended industrial (–40°C to +125°C) temperature range. The dual ADA4096-2 is available in 8-lead LFCSP (2x2) and 8-lead MSOP packages. Rev.
