The 50 µA quiescent current is low enough for battery-powered instrumentation where every microamp counts. ## Noise and drift for precision chains Output noise is specified at 28 µVp-p (0.1 Hz to 10 Hz) and 80 µVrms (10 Hz to 10 kHz). For a 16-bit ADC with a 2.5V reference, the noise contribution from the reference is below 1 LSB, making it suitable for measurement and data-acquisition systems.","metaTitle":"REF3025AIDBZRG4 2.5V Series Voltage Reference, ±0.2%","metaDescription":"Texas Instruments REF3025AIDBZRG4 precision 2.5V series voltage reference. ±0.2% initial accuracy, 75ppm/°C drift, 25mA output, -40°C to 125°C.
