The Microchip Technology MCP3421A0T-E/CH is a high-accuracy, 18-bit Sigma-Delta Analog-to-Digital Converter (ADC) designed for differential input operation. It features an on-board 2.048V voltage reference with ±0.05% accuracy and a low drift of 15 ppm/°C. The device supports programmable gain amplifier (PGA) settings of 1, 2, 4, or 8, allowing for conversion of smaller input signals with high resolution. The Integral Non-Linearity (INL) is rated at 10 ppm of FSR.
This ADC offers programmable data rates including 3.75 SPS (18 bits), 15 SPS (16 bits), 60 SPS (14 bits), and 240 SPS (12 bits), with options for one-shot or continuous conversion modes. It utilizes a two-wire I2C compatible serial interface, supporting Standard, Fast, and High-Speed modes. The device operates from a single supply voltage ranging from 2.7V to 5.5V and is specified for an extended temperature range of -40°C to +125°C.
Packaged in a compact SOT-23-6 surface mount package, the MCP3421A0T-E/CH is suitable for applications requiring high precision and low power consumption in a small footprint. Typical applications include portable instrumentation, weigh scales, fuel gauges, temperature sensing, and bridge sensing for pressure, strain, and force measurements.
