Microchip MCP3021 ADC (I2C)
Summary
10-bit analog-to-digital converter with I2C interface for single-channel voltage measurement.
Description
The MCP3021 component is a successive approximation ADC that provides 10-bit resolution for single-ended analog voltage measurements. It features a simple I2C interface, low power consumption, and operates from 2.7V to 5.5V. The converter includes an internal sample-and-hold circuit and provides conversion results through direct I2C read operations. Typical applications include battery monitoring, sensor interfacing, and system monitoring where simple analog-to-digital conversion is required.
