3-V, low-drift, low-power, small-footprint series voltage reference

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.
