The MAXQ314 performs voltage and current measurements using an integrated ADC that can measure voltage and current. Other values such as power are calculated from that data. The MAXQ314 also has an integrated temperature sensor that provides the die temperature on demand. The internal current amplifier produces up to 32x gain and the voltage amplifier gain is 1x.
