High-precision CMOS Voltage Reference LTR33xx with Low Temperature Drift (20ppm/℃ Maximum) and Low Power Consumption (Less Than 500μA)

PublishTime： 2024-01-19 Article Source：LINEARIN

The LTR33 series devices are low temperature drift (20ppm/℃ maximum), low-power, high-precision CMOS voltage reference, featuring ±0.1% initial accuracy, and low operating current with a power consumption of less than 500μA. This device also offers a very low output noise of 15μVPP/V, which enables its ability to maintain high signal integrity with high-resolution data converters in noise critical systems.

Packaged in the same SOT23-3 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℃.
