The MCP3221A1T-E/OT is a single channel analog-to-digital converter (ADC) from Microchip Technology. It utilizes successive approximation register (SAR) technology to achieve high conversion speeds of up to 22.3 kilo samples per second (ksps) with a resolution of 12 bits. This automotive-grade ADC is housed in a compact 5-pin SOT-23 package, making it suitable for space-constrained applications. It also features a serial interface for easy integration into digital systems. The MCP3221A1T-E/OT is supplied in tape and reel packaging for convenient manufacturing and assembly processes.
