18-Bit ADC with I2C Interface and Onboard Reference DS

    The MCP3421 is a single channel low-noise, high accuracy ΔΣ A/D converter with differential inputs and up to 18 bits of resolution in a small SOT-23-6 package. The on-board precision 2.048V reference voltage enables an input range of ±2.048V differentially (Δvoltage = 4.096V). The device uses a two-wire I2C
