It delivers a ±0.5% initial tolerance and a 100 ppm/°C temperature coefficient, making it suitable for precision bias and ADC reference circuits in under-hood and cabin electronics.
The ±0.5% tolerance keeps the total error budget under 1% when combined with the ADC's own INL, avoiding the need for a trim pot in production. Output current is rated 12 mA, with a cathode current of 65 µA. The low cathode current means the reference draws minimal bias from the supply rail, which matters in battery-backed or always-on automotive modules where every microamp counts. Noise is specified at 20 µVrms over 10 Hz to 10 kHz. For a 12-bit ADC with a 3.3 V reference, this noise contribution is below 0.1 LSB, so it does not degrade the converter's effective resolution in most automotive sensor interfaces.
SOT-23-3 package and temperature range
The SOT-23-3 footprint is a common industry standard, so board layout reuse across reference designs is straightforward.
