Texas Instruments REF3425
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).FEATURES
