Description and Introduction

Precision Micropower, Low Dropout, Low Voltage References, Nom. Vo=2.048 **Introducing the REF191: Precision Voltage Reference for Demanding Applications**  

In today’s high-performance electronic systems, precision and stability are non-negotiable. The REF191 stands out as a high-accuracy voltage reference, delivering exceptional performance for applications requiring reliable voltage regulation. With its ultra-low noise, low temperature drift, and outstanding long-term stability, the REF191 is engineered to meet the stringent demands of industrial, medical, and automotive systems.  

Designed for precision, the REF191 offers an initial accuracy of ±0.04% and a temperature coefficient as low as 3 ppm/°C, ensuring consistent performance across varying environmental conditions. Its low output noise of 3.5 µVp-p (0.1 Hz to 10 Hz) makes it ideal for sensitive analog circuits, such as data acquisition systems, precision instrumentation, and high-resolution ADCs.  

The REF191 operates over a wide supply voltage range, from 4.5V to 18V, while consuming minimal quiescent current, making it suitable for both battery-powered and line-powered designs. Its robust design includes reverse-battery protection and short-circuit resilience, enhancing system reliability in harsh operating environments.  

Available in multiple output voltage options (2.048V, 2.5V, 3.0V, 3.3V, 4.096V, and 5.0V), the REF191 provides flexibility for diverse circuit requirements. Housed in a compact 8-pin SOIC package, it integrates seamlessly into space-constrained designs without compromising performance.  

For engineers seeking a dependable voltage reference that combines precision, low power consumption, and ruggedness, the REF191 is a compelling choice. Its proven performance in critical applications underscores its role as a key component in next-generation electronic systems.  

Whether optimizing a medical device’s signal chain or ensuring measurement accuracy in industrial controls, the REF191 delivers the stability and precision needed for superior system performance.
