The MCP3421 Battery Fuel Gauge Demo Board demonstrates how to measure the battery voltage and discharging current using the MCP3421.
The MCU algorithm calculates the battery fuel being used. This demo board is shipped with 1.5V AAA non-rechargeable battery. The demo board displays the following parameters:
Measured battery voltage.
The MCP3422 Evaluation Board (P/N MCP3422EV) contains an MCP3422 18-bit Delta-Sigma Analog-to-Digital Converter (ADC). The MCP3422 is a 2-channel ADC device with various options. The board has analog input connection pads and various test pads. The user can connect inputs and test the conversion results using the PICkit Serial Analyzer and its PC graphic user interface (GUI).
