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.
