概述
Description
The TPL0102-100RUCR is a dual-channel, 256-tap digital potentiometer from Texas Instruments. It provides non-volatile memory, retaining settings when powered off, and operates over a wide voltage range (2.7V–5.5V). Each channel offers 256 programmable resistance steps with an end-to-end resistance of 100 kΩ.
Key features include:
- I²C interface for easy digital control.
- Low power consumption (0.5 µA standby current).
- High reliability (200,000 write cycles).
Applications include volume control, LCD bias adjustment, and programmable voltage references. The RUCR suffix denotes a 10-pin UQFN package, making it compact for space-constrained designs.
