The LTR30 series devices are low temperature drift (30 ppm/⁰C maximum), low-power, high-precision CMOS

voltage reference, featuring ±0.15% initial accuracy, low operating current with power consumption less than

500 μA. This device also offers very low output noise of 15 μVPP/V, which enables its ability to maintain high

signal integrity with high-resolution data converters in noise critical systems.

Packaged in the same SOT-23-3 package, LTR30xx offers enhanced specifications and pin-to-pin replacement

for REF30xx and LM4132. Stability and system reliability are further improved by the low output-voltage

hysteresis of the device and low long-term output voltage drift. LTR30xx is specified for the wide temperature

range of −40 to +125⁰C.
