MCP3221A0T-E/OT

MCP3221A0T-E/OT is a 12bit, low power, 2-wire serial successive approximation A/D converter with IC interface. It provides one single-ended input with very low-power consumption. Low-current consumption, combined with the small package, make this device ideal for battery powered and remote data acquisition applications. It is performed using a 2-wire, I2C compatible interface. 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. Application includes data logging, multi-zone monitoring, handheld portable applications, battery-powered test equipment, remote or isolated data acquisition.
