MCP3021 is a successive approximation A/D 23converter (ADC) with 10-bit resolution. The MCP3221 has 12-bit resolution. 24 25These devices provide one single-ended input with very low power consumption. 26Communication to the MCP3021/MCP3221 is performed using a 2-wire I2C 27compatible interface. Standard (100 kHz) and Fast (400 kHz) I2C modes are 28available. The default I2C device address is 0x4d (contact the Microchip 29factory for additional address options). 30
