描述 Description

The LTR30 series devices are low temperature drift (30 ppm/?C maximum), low-power, high-precision CMOSvoltage reference, featuring ±0.15% initial accuracy, low operating current with power consumption less than500 μA. This device also offers very low output noise of 15 μVPP/V, which enables its ability to maintain highsignal 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 replacementfor REF30xx and LM4132. Stability and system reliability are further improved by the low output-voltagehysteresis of the device and low long-term output voltage drift. LTR30xx is specified for the wide temperaturerange of ?40 to +125?C.
