Description

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.
