Fixed 3V reference for precision signal chains
The Texas Instruments REF3330AIDBZR is a series voltage reference that delivers a fixed 3V output with ±0.15% initial accuracy and a temperature coefficient of 30 ppm/°C. It operates from a 3.2V to 5.5V input rail and draws only 8.5 µA supply current, making it a fit for battery-powered instrumentation and portable sensor interfaces.
Noise floor and system accuracy
Low-frequency noise is specified at 84 µVp-p. The 30 ppm/°C drift keeps the output stable across temperature.
