LTR3330T20YT3

The LTR33 series devices are low temperature drift (20 ppm/°C maximum), low-power, high-precision CMOS voltage reference, featuring ± 0.1% 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, 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°C.
