REF3033AIM3/TR

The REF30xx series are low temperature drift (30 ppm/°C max), low power, high precision CMOS voltage references with ±0.15% initial accuracy and low operating current with power consumption below 500 μA. These devices also provide very low output noise of 15 μVₚ₋ₚ/V, enabling them to work alongside high-resolution data converters in noise-sensitive systems while maintaining high signal integrity. Using the same SOT-23-3 package, the REF30xx offers enhanced specifications and pin-to-pin replacement for the REF30xx and LM4132. Low output voltage hysteresis and low long-term output voltage drift further improve stability and system reliability. The REF30xx operates over a wide temperature range of -40°C to +125°C.
