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