Brand: Microchip
Category: ADC & DAC Converter IC

The MCP3421A1T-E/CH is a 1-channel low-noise high accuracy delta-sigma Analogue-to-Digital Converter with differential inputs and up to 18-bit of resolution. 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. The MCP3421 device performs conversions at rates of 3.75, 15, 60 or 240 samples per second depending on user controllable configuration bit settings using the two-wire I²C™ compatible serial interface. This device has an onboard programmable gain amplifier (PGA). User can select the PGA gain of x1, x2, x4 or x8 before the analogue-to-digital conversion takes place. This allows the MCP3421 device to convert a smaller input signal with high resolution. The device has two conversion continuous and one-shot modes.


Features:

  • Differential input operation
  • Onboard voltage reference with 5ppm/°C drift
  • Onboard PGA
  • INL 10ppm of FSR maximum
  • 145µA at 3V Low current consumption
  • One-shot or continuous conversion options
  • Self calibration of internal offset and gain per each conversion
