The I²C data interface keeps the pin count low; the part communicates over two wires and leaves the remaining processor pins free for other tasks. Housed in a 5-lead SOT-23 (SC-74A) package, the ADC occupies minimal board area and suits dense mixed-signal layouts where every square millimeter counts.","metaTitle":"Microchip MCP3021A0T-E/OT 10-bit SAR ADC, 22.3k S/s, I²C","metaDescription":"Active 10-bit SAR ADC, 22.3k samples/sec, I²C interface, 2.7V-5.5V supply, SOT-23-5, -40°C to 125°C.
