TPL0102-100RUCR

Digital Potentiometers Overview

The TPL0102-100RUCR is a dual-channel digital potentiometer IC manufactured by Texas Instruments. It features two independent channels, each with 256 taps and a total end-to-end resistance of 100 kOhms. The device utilizes an I2C serial interface for control and includes non-volatile memory to retain wiper positions during power-off events. Operating within a supply voltage range of 2.7 V to 5.5 V, it exhibits a typical temperature coefficient of 92 PPM/C and a tolerance of ±20%. The component is housed in a compact 14-pin X2QFN package (2x2 mm) suitable for surface-mount applications.

Digital Potentiometers Feature Summary

• Dual-channel architecture with 256 discrete tap positions per channel
• Non-volatile memory retains wiper settings across power cycles
• I2C serial interface supporting standard and fast modes
• Linear taper with 100 kOhm nominal resistance

Digital Potentiometers Applications

• Programmable gain amplifiers requiring precise resistance adjustment
• Voltage reference trimming in data acquisition systems
• Audio volume control circuits with digital interface requirements
• Sensor biasing and calibration networks

Digital Potentiometers Procurement Notes

Verify the specific suffix RUCR corresponds to the X2QFN-14 package and industrial temperature range (-40°C to +85°C). Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets prior to integration. Ensure I2C address configuration matches system design constraints.

Digital Potentiometers Selection Notes

Select this model when dual independent digital potentiometers are required in a minimal footprint. The 100 kOhm value suits high-impedance signal paths. Verify that the 256-tap resolution meets application granularity needs. Consider the 92 PPM/C temperature coefficient for thermal stability requirements in the operating environment.

Digital Potentiometers Part Context

This part belongs to the TPL0102 family of digital potentiometers from Texas Instruments. It shares core functionality with variants like the TPL0102-100PWR but differs in packaging. The RUCR suffix specifically denotes the 14-pin X2QFN form factor, distinguishing it from TSSOP or other package options within the same electrical specification set.

Digital Potentiometers Replacement Considerations

Direct pin-compatible replacements include other TPL0102 variants such as TPL0102-100PWR if package adaptation is feasible. Verify that substitute components maintain identical I2C command sets and non-volatile memory behavior.
