Texas Instruments TPL0401A / TPL0401B 128 TAPS Digital Potentiometers
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 connected to GND. The position of the wiper can be adjusted using an I²C interface. The TI TPL0401A and TPL0401B Digital Potentiometers are designed for use in setting the voltage reference for low power DDR3 memory.
