LMP92064 Description
The LMP92064 is a precision low-side digital current sensor and voltage monitor with a digital SPI interface. This analog frontend (AFE) includes a precision current sense amplifier to measure a load current across a shunt resistor and a buffered voltage channel to measure the voltage supply of the load. The current and voltage channels are sampled simultaneously by independent 125-kSps, 12-bit ADC converters,...
