The TPL1401 is a digital potentiometer (digipot) with a buffered wiper. Unlike standard digipots, this device offers higher load regulation in voltage-divider applications as a result of the integrated buffered wiper.

The TPL1401 makes in-factory calibration and trimming easier with integrated nonvolatile memory (NVM), and a simple I2C digital interface to communicate with the device. This device supports I2C standard mode (100 kbps), fast mode (400 kbps), and fast mode plus (1 Mbps).

The TPL1401 operates with either the internal reference or with the power supply as the reference, and provides a full-scale output of 1.8 V to 5.5 V. This device also includes a wiper lock feature, a feedback (FB) pin for current-sink applications, and two bytes of user-programmable NVM space. The TPL1401 has a power-on-reset (POR) circuit that makes sure all the registers start with default or user-programmed settings using NVM. The digipot output powers on in high-impedance mode (default); this setting can be programmed to 10kΩ-GND using NVM.

The TPL1401 is tiny, feature rich, and an easy-to-use building block device that can be integrated into many applications.

The TPL1401 operates within the temperature range of –40°C to +125°C.
