The Texas Instruments REF1941AIDDCR is a low-drift, low-power, dual-output voltage reference IC. It provides a stable VREF and a VREF/2 output, making it suitable for applications requiring a voltage reference in the middle of a single-supply system's analog-to-digital converter (ADC) input range.
Key electrical characteristics include a high initial accuracy of ±0.1% (max) and excellent temperature drift performance of 25 ppm/°C (max) over the -40°C to 125°C operating range. The device also features tight tracking between VREF and VBIAS over temperature, low dropout voltage of 10 mV, and high output current capability of ±20 mA. Its low quiescent current of 360 µA contributes to power efficiency.
Designed for convenience in single-supply systems, the REF1941AIDDCR is housed in a microsize SOT23-5 (DDC) package, suitable for surface mounting. This compact form factor and its precise voltage reference capabilities make it a valuable component for various analog circuit designs.
