10k I2C Digital Potentiometer with 128 Wiper Positions for Voltage Reference and Analog Adjustment in SC-70-6 Package
The TPL0401B-10DCKR is a single-channel digital potentiometer designed for precise resistance adjustment in embedded and analog circuits. Developed by Texas Instruments, this device provides a 10k end-to-end resistance with 128 wiper positions and is controlled via an I2C serial interface, allowing digital control of analog voltage levels directly from microcontrollers or processors.
The device features a linear taper configuration where the low terminal is internally connected to ground, simplifying circuit design in voltage divider applications. With a wide operating voltage range of 2.7V to 5.5V and an industrial temperature range from 40C to +125C, the TPL0401B-10DCKR is suitable for precision voltage reference adjustment, DDR3 memory voltage tuning, signal calibration, and embedded system control. Its ultra-compact SC-70-6 package makes it ideal for space-constrained designs in consumer electronics, computing, and industrial hardware.
