The REF2125 device is a low temperature drift
(6 ppm/°C), low-power, high-precision CMOS voltage reference, featuring ±0.05% initial accuracy, low operating current with power consumption less than 95 µA. This device also offers very low output noise of 5 µVp-p /V, which enables its ability to maintain high signal integrity with high-resolution data converters and noise critical systems.
Stability and system reliability are further improved by the low output-voltage hysteresis of the device and low long-term output voltage drift. Furthermore, the small size and low operating current of the devices (95 µA) make them ideal for portable and battery-powered applications.
REF2125 is specified for the wide temperature range of −40°C to +125°C. Contact the TI sales representative for additional voltage options.
