The MCP3421A1T-E/CH from Microchip Technology is a high-accuracy, low-noise, 18-bit Sigma-Delta Analog-to-Digital Converter (ADC) designed for precision measurements. 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 and operates from a single supply voltage ranging from 2.7V to 5.5V. It offers programmable data rates from 3.75 SPS (18 bits) up to 240 SPS (12 bits), along with an on-board Programmable Gain Amplifier (PGA) with selectable gains of 1, 2, 4, or 8. Conversion can be performed in either one-shot or continuous modes, with low current consumption.
The device is housed in a compact SOT-23-6 package, making it suitable for applications where space is a constraint. Its extended operating temperature range of -40°C to +125°C ensures reliable performance in demanding environments. Typical applications include portable instrumentation, weigh scales, fuel gauges, and sensor measurements for temperature, pressure, strain, and force.
Key specifications include an integral non-linearity (INL) of 10 ppm of FSR, and low current consumption of 145 µA typical during continuous conversion and 39 µA typical in one-shot mode at 1 SPS.
