MCP3221A5T in Microchip MCP3xxx ADC Family
The MCP3221A5T is a 12-bit successive approximation register (SAR) Analog-to-Digital Converter developed by Microchip Technology. Operating over a wide voltage range with an I2C interface, this single-channel converter is designed for space-constrained applications requiring high-resolution data acquisition. It features a low current consumption profile and simple 5-pin SOT-23 packaging, making it a reliable choice for remote sensing and portable instrumentation where board space and power efficiency are critical constraints.
Variants in This Sub-Family
Variants within the MCP3221 family are primarily distinguished by their factory-set I2C device addresses, denoted by the alphanumeric suffix (e.g., A0 through A7). This allows up to eight identical devices to reside on the same I2C bus without address conflicts. Additionally, temperature grade suffixes like 'E' for Extended (-40C to +125C) or 'I' for Industrial (-40C to +85C) define the qualified operating environment and thermal performance limits.
