Texas Instruments TPL0401A and TPL0401B 128 TAPS Single-Channel Digital Potentiometers with I2C Interface are linear-taper devices with 128 wiper positions. TI TPL0401 Digital Potentiometers feature 10kΩ end-to-end resistance options and 2.7V to 5.5V single-supply operation. The TPL0401A and TPL0401B have the low terminal internal and are connected to GND. The position of the wiper can be adjusted using an I2C interface. The Texas Instruments TPL0401A and TPL0401B Digital Potentiometers are designed for use in setting the voltage reference for low power DDR3 memory.
