Microchip’s MCP3221 is a successive approximation A/D converter (ADC) with a 12-bit resolution. Available in the SOT-23 package, 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 µA and 1 µA, respectively. Low-current consumption, combined with the small SOT-23 package, make this device ideal for batterypowered and remote data acquisition applications. Communication to the MCP3221 is performed using a 2-wire, I2C compatible interface. Standard (100 kHz) and Fast (400 kHz) 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. The MCP3221 runs on a single-supply voltage that operates over a broad range of 2.7V to 5.5V. This device also provides excellent linearity of ±1 LSB differential nonlinearity (DNL) and ±2 LSB integral nonlinearity (INL), maximum.
