The REF34xx device is a low temperature drift (6ppm/°C), low-power, high-precision CMOS voltage reference, featuring ±0.05% initial accuracy, low operating current with power consumption less than 95µA. This device also offers very low output noise of 3.8µVp-p /V, which enables its ability to maintain high signal integrity with high-resolution data converters in noise critical systems. With a small SOT-23 package, REF34xx offers enhanced specifications and pin-to-pin replacement for MAX607x, ADR34xx and LT1790 (REF34xxT, no EN pin). The REF34xx family is compatible to most of the ADC and DAC such as ADS1287, DAC8802 and ADS1112.

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 (95µA) benefit portable and battery-powered applications.

REF34xx is specified for the wide temperature range of −40°C to +125°C.
