ANALOG DEVICES AD5162WBRMZ100-RL7 Volatile Digital Potentiometer, 100 kohm, Dual, 3 Wire, SPI, Linear, ± 20%, 2.7 V

AD5162WBRMZ100-RL7 is a dual-channel, 256-position, SPI digital potentiometer. This low-temperature coefficient device is ideal for high accuracy and stability-variable resistance adjustments. The wiper settings are controllable through an SPI digital interface. The resistance between the wiper and either endpoint of the fixed resistor varies linearly with respect to the digital code transferred into the RDAC latch. Operating from a 2.7V to 5.5V power supply and consuming less than 6µA allows the device to be used in portable battery-operated applications. It is used in applications such as systems calibrations, electronics level settings, mechanical trimmers replacement in new designs, permanent factory PCB setting, transducer adjustment of pressure, temperature, position, chemical, and optical sensors, RF amplifier biasing, automotive electronics adjustment, gain control and offset adjustment.
