Texas Instruments Digital Potentiometers TPL1401DSGRQ1

The TPL1401DSGRQ1 is a 256-position digital potentiometer designed for voltage-divider applications, featuring a buffered wiper that enhances load regulation. It operates within a power supply range of 1.8 V to 5.5 V and can function in temperatures from ,Äì40°C to +125°C. The device supports an I²C interface with multiple modes, including standard, fast, and fast plus, allowing for flexible communication. Key features include user-programmable nonvolatile memory for saving and recalling register settings, a wiper lock function to prevent accidental writes, and a feedback pin for precision current sink applications. The TPL1401 also offers a low power consumption of 0.2 mA at 1.8 V and comes in a compact 8-pin WSON package measuring 2 mm x 2 mm. This digital potentiometer is suitable for various applications, including exit lighting, barcode scanners, smart speakers, and robotic devices.
