The MCP3021A5T-E/OT is a 10-bit low power Analogue-to-digital Converter (ADC). This device provides one/single-ended input with very low power consumption. The MCP3021 provides a low maximum conversion current and standby current of 250μA and 1μA respectively. Communication to the MCP3021 is performed using a 2-wire I2C? compatible interface. Standard (100kHz) and fast (400kHz) I2C? compatible modes are available with the device. An on-chip conversion clock enables independent timing for the I2C? compatible clock and the conversion clock. The device is also addressable allowing up to eight devices on a single 2-wire bus. The MCP3021 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 ±1 LSB differential non-linearity and ±1 LSB integral non-linearity. Operating temperature range for this device is -40 to +125°C. Ideal for battery-powered and remote data acquisition applications.
