Description
The MCP39F511A device is a highly-integrated,
complete single-phase power-monitoring IC designed
for real-time measurement of input power for AC or DC
power supplies, making it suitable for a wide range of
consumer and industrial applications. It is capable of
detecting the input voltage in order to work as DC or AC
mode. It includes dual-channel Delta-Sigma ADCs, a
16-bit calculation engine, EEPROM and a flexible
2-wire interface. Separate AC and DC calibration
registers are provided, to ensure high-accuracy
measurements in both modes. An integrated low-drift
voltage reference with 7 ppm/°C in addition to 94.5 dB
of SINAD performance on each measurement channel
allows for better than 0.1% accurate designs across a
4000:1 dynamic range.
