The MCP3421A3T-E/CH from Microchip Technology is a high-accuracy, low-noise, 18-bit Sigma-Delta Analog-to-Digital Converter (ADC) designed for demanding applications. It features differential input operation and an on-board 2.048V voltage reference, enabling an input range of ±2.048V.
This ADC supports a programmable gain amplifier (PGA) with gains of 1, 2, 4, or 8, allowing for conversion of smaller input signals with high resolution. It offers programmable data rates including 3.75 SPS for 18-bit resolution. The device communicates via a two-wire I2C compatible serial interface and operates from a single 2.7V to 5.5V power supply.
Packaged in a compact SOT-23-6 surface-mount package, the MCP3421A3T-E/CH is suitable for space-constrained designs. It operates across an extended temperature range of -40°C to 125°C, making it robust for various environmental conditions. Typical applications include portable instrumentation, weigh scales, fuel gauges, and temperature sensing.
Key electrical specifications include an integral nonlinearity error of 10 ppm of FSR and a full-scale error of 0.35%FSR. The device also features self-calibration for internal offset and gain per conversion.
