LTR3320T20YT3

The LTR33 series devices are low temperature drift (20 ppm/°C max), low power, high-precision CMOS voltage references featuring ±0.1% initial accuracy and low operating current with less than 500 μA power consumption. The devices also provide ultralow output noise of 15 μVpp/V, enabling them to work with high-resolution data converters in noise-critical systems while maintaining high signal integrity. Using the same SOT-23-3 package, these devices offer enhanced specifications and pin-to-pin replacement for REF33xx and LM4132. Low output voltage hysteresis and low long-term output voltage drift further improve stability and system reliability. The LTR33xx is specified for an operating temperature range of -40 to +125°C.
