2.048 V shunt reference with ±0.2% initial tolerance
The ADR5040WARTZ-R7 from Analog Devices is a precision shunt voltage reference that delivers a fixed 2.048 V output with an initial accuracy of ±0.2%. It is part of the ADR504 series and comes in a surface-mount SOT-23-3 package. The reference is designed for applications requiring a stable, low-drift voltage reference over a wide temperature range, such as automotive sensor interfaces, industrial control loops, and precision ADC biasing.
Active lifecycle — no LTB risk for new designs
It is ROHS3 compliant, so it meets the latest EU restriction-of-hazardous-substances requirements.
Package and mounting
The part is supplied in a SOT-23-3 package (also described as TO-236-3 / SC-59), a three-lead surface-mount footprint that fits standard pick-and-place assembly. No heatsinking is required for the shunt reference at typical bias currents; the SOT-23-3 body dissipates the power internally within the 15 mA output limit.
