LTR33xx Low-Drift, Low-Power, Small-Footprint Series Voltage Reference Data Sheet
■The LTR33 series devices are low temperature drift (20 ppm/℃ maximum), low-power, high-precision CMOS voltage reference, featuring ±0.1% initial accuracy, low operating current with power consumption less than 500μA. 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, LTR33xx offers enhanced specifications and pin-to-pin replacement for REF33xx 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. LTR33xx is specified for the wide temperature range of-40 to +125℃
