REF1112AIDBZR Description

Short technical summary and product information.

The Texas Instruments REF1112AIDBZR is a two-terminal shunt voltage reference ideal for power and space-sensitive applications. It provides a fixed reverse breakdown voltage of 1.25V with a maximum initial accuracy of ±0.2% and a temperature coefficient of 50ppm/°C. The device operates with a low current range from 1.2µA to 5mA, making it highly efficient.

Designed for ease of use, the REF1112AIDBZR is available in a small SOT-23-3 package, suitable for surface mount assembly. Its key specifications include a low output noise of 25µVpp (0.1Hz to 10Hz) and an operating temperature range of -40°C to +125°C. This makes it a versatile component for various electronic designs requiring a stable voltage reference.

This voltage reference is an improved, lower power option compared to references in larger packages. It complements designs that previously used parts like the REF1004 and LT1004, offering enhanced performance in a smaller footprint.
