MCP3421A0T in Microchip MCP3xxx ADC Family
The MCP3421A0T series by Microchip Technology consists of high-precision, 18-bit delta-sigma analog-to-digital converters designed for high-resolution measurement applications. These ADCs feature a self-calibration architecture that ensures minimal offset and gain error over time and temperature. Integrated with a low-noise programmable gain amplifier and an on-board precision voltage reference, the family provides a compact, single-channel solution for converting low-level analog signals into digital data via a standard I2C serial interface.
Variants in This Sub-Family
The MCP3421A0T sub-family primarily differentiates through factory-programmed I2C address bits. While the A0 variant is the most common, other versions like A1 through A7 exist to allow multiple devices to reside on the same I2C bus without address conflicts. All variants share the same SOT-23-6 footprint and internal specifications, including the 2.048V internal reference and differential input stages.
