The MCP3421A2T-E/CH from Microchip Technology is a high-accuracy, low-noise, 18-bit Sigma-Delta Analog-to-Digital Converter (ADC) designed for applications requiring precise data conversion in a small footprint. It features differential input operation and an on-board voltage reference with an accuracy of ±0.05% and a drift of 15 ppm/°C.
This ADC supports an I2C serial interface, allowing for communication in Standard, Fast, and High-Speed modes. It offers programmable data rates from 3.75 SPS (18 bits) up to 240 SPS (12 bits) and includes an on-board Programmable Gain Amplifier (PGA) with selectable gains of 1, 2, 4, or 8. The device operates from a single supply voltage ranging from 2.7V to 5.5V.
With its extended temperature range of -40°C to +125°C, the MCP3421A2T-E/CH is suitable for various demanding applications. It can operate in either continuous or one-shot conversion modes, with the one-shot mode offering reduced current consumption for power-sensitive designs. Typical applications include portable instrumentation, weigh scales, fuel gauges, and temperature sensing.
The device is housed in a compact SOT-23-6 surface-mount package, making it ideal for space-constrained designs. Its self-calibration feature ensures high accuracy per conversion.
