The REF34xx device is a low temperature drift
(6 ppm/°C), low-power, high-precision CMOS voltage reference, featuring ±0.05% initialaccuracy, low operating current with power consumption less than 95 µA. This device also offersvery low output noise of 3.8 µVp-p /V, which enables its ability to maintainhigh signal integrity with high-resolution data converters in noise critical systems. With a smallSOT-23 package, REF34xx offers enhanced specifications and pin-to-pin replacement for MAX607x andADR34xx. The REF34xx family is compatible to most of the ADC and DAC such as ADS1287, ADUCM360,ADS1112.
Stability and system reliability are further improved by the low output-voltagehysteresis of the device and low long-term output voltage drift. Furthermore, the small sizeand low operating current of the devices (95 µA) can benefit portable and battery-poweredapplications.
REF34xx is specified for the wide temperature range of −40°C to +125°C. Contact the TIsales representative for additional voltage options.
