The MCP3428-E/SL is a 4-channel 16-bit Analogue-to-digital Converter (ADC) with I2C? interface and on-board reference. The on-board precision 2.048V reference voltage enables an input range of ±2.048V differentially. The device uses a two-wire I2C? compatible serial interface and operates from a single power supply ranging from 2.7 to 5.5V. This devices can output analogue-to-digital conversion results at rates of 240 (12-bit mode) samples per second depending on the user controllable configuration bit settings using the two-wire I2C serial interface. During each conversion, the device calibrates offset and gain errors automatically. This provides accurate conversion results from conversion to conversion over variations in temperature and power supply fluctuation.
