uS5651P ADC Prefilter with Analog Multiplexer General Description The uS5651P is an ADC prefilter with analog multiplexer, which output is used mainly by the analog to digital converter (ADC) of GPU/ASIC for voltage and current monitoring. This device has four input channels, and each channel has an independent voltage and current monitoring input. This part senses the voltage across the shunt resistor for current monitoring. The voltage and current information of each channel is processed and scaled then sent to a differential output via a multiplexer. The multiplexer selects which channel to be the signal source in a switching manner. The operating mode, switching sequence, scaling factor and other parameters are set by the I2C register. The device operates with 3.
