The MCP3221A7T-E/OT is a low-power, 12-bit analog-to-digital converter (ADC) featuring a single-ended input and an I²C compatible serial interface. It operates with a maximum conversion current of 250 µA and a typical standby current of 5 nA, making it suitable for battery-powered applications. The device supports I²C communication at standard (100 kHz) and fast (400 kHz) modes, allowing up to eight devices to be connected on a single 2-wire bus. It has a specified operating voltage range of 2.7V to 5.5V and is designed to function across an extended temperature range of -40°C to +125°C. The MCP3221A7T-E/OT is housed in a compact SOT-23-5 package, which is advantageous for space-constrained designs. Its performance includes a maximum differential nonlinearity (DNL) of ±1 LSB and integral nonlinearity (INL) of ±2 LSB, ensuring reliable data conversion. This ADC is ideal for applications such as data logging, multi-zone monitoring, and remote data acquisition.
