The MCP3221A5T-E/OT is a successive approximation A/D Converter with 12-bit resolution. This device provides one single-ended input with very low power consumption. Based on an advanced CMOS technology, the MCP3221 provides a low maximum conversion current and standby current of 250 and 1μA respectively. Low current consumption, make this device ideal for battery-powered and remote data acquisition applications. Communication to the MCP3221 is performed using a 2-wire, I2C compatible interface. The converter with standard (100kHz) and fast (400kHz) I2C modes. An on-chip conversion clock enables independent timing for the I2C and conversion clocks. The device is also addressable, allowing up to eight devices on a single 2-wire bus.
