The MCP3221A5T-I/OT is a 12-bit low power successive approximation Analog-to-digital Converter (ADC) with I²C™ interface. This device provides one single-ended input with very low power consumption. Based on an advanced CMOS technology, the ADC 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 ADC is performed using a 2-wire, I²C compatible interface. Standard and fast I²C modes are available with the device. 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. It runs on a single supply voltage that operates over a broad range of 2.7 to 5.5V. This device also provides excellent linearity of ±1LSB differential non-linearity and ±2LSB integral non-linearity maximum.
