MICROCHIP  MCP4661-503E/ST  非易失性数字电位器, AEC-Q100, 50 kohm, 双, I2C, 串行, 线性, ± 20%, 2.7 V

The is a Digital Potentiometer with non-volatile memory. It offers a wide range of product offerings using an I²C interface. This family of device supports 7-bit and 8-bit resistor networks, non-volatile memory configurations and potentiometer and rheostat pin-outs. It features zero-scale to full-scale wiper operation and resistor network terminal disconnect via the terminal control TCON register. The potentiometer"s terminal A is the fixed connection to the full-scale wiper value of the digital potentiometer. The potentiometer"s terminal B is the fixed connection to the zero scale wiper value of the digital potentiometer. The SCL pin is the serial interfaces serial clock pin. The VDD pin is the device"s positive power supply input. The input power supply is relative to VSS. The pad is conductively connected to the potentiometer"s substrate. This pad should be tied to the same potential as the VSS pin or left unconnected.
