This reference design is a fixed-gain amplifier stage for measuring low-amplitude voltage and current inputs accurately over a wide dynamic range using SAR ADC for power measurement applications. Low-amplitude AC voltage from voltage dividers, current transformers or split-core current sensors with a 333-mV output can be accurately measured.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
