MCP3221 A/D Converters

Microchip Technology MCP3221 A/D Converters are successive approximation analog to digital converters with 12-bit resolution. These Microchip A/D converters are based on advanced CMOS technology and provide a maximum standby current of 1µA and 250µA conversion current. The MCP3221 A/D converters feature single-ended input, low power consumption, on-chip conversion clock, I²C™ compatible serial interface, on-chip sample, and hold. These A/D converters communicate via a 2-wire I²C compatible interface, which includes both 100kHz standard and 400kHz fast modes.
