The REF34xx-EP device is a low temperature drift
(10 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 3.8 µVp-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-EP offers enhanced specifications and pin-to-pin replacement for MAX607x and ADR34xx. The REF34xx-EP family is compatible to most ADC and DAC.

Stability and system reliability are further improved by the low output-voltage hysteresis of the device and low long-term output voltage drift. The small size and low operating current of the devices (95 µA) can benefit portable and battery-powered applications.

REF34xx-EP is specified for the wide temperature range of –55°C to 125°C. Contact the TI sales representative for additional voltage options.
