• The REF34xx device is a low temperature drift
(6 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 offers enhanced specifications and pin-topin 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. Initial accuracy: ±0.05% (maximum)
Temperature coefficient : 6 ppm/°C (maximum)
Operating temperature range: −40°C to +125°C
Output current: ±10 mA
Low quiescent current: 95 μA (maximum) …
