4.5 V series reference — accuracy and drift for precision bias
The MAX6045BEUR is a series voltage reference from Analog Devices, delivering a fixed 4.5 V output with ±0.4% initial tolerance and a 30 ppm/°C temperature coefficient. Its 4.7 V to 12.6 V input range lets it run from common 5 V or 12 V rails, while the 500 µA output capability and 35 µA supply current keep the power budget lean in battery-powered or multi-rail analog chains.
Noise floor and signal-chain fit
As a series reference, the MAX6045BEUR does not require an external resistor to set the output current, simplifying the BOM and improving load regulation compared to a shunt reference.
Package and temperature grade
Housed in a SOT-23-3 (TO-236, SC-59) surface-mount package, the part occupies minimal board area and is suited for compact mixed-signal designs.
Lifecycle and compliance note
Note that this part is marked RoHS non-compliant; confirm local regulatory requirements before specifying for RoHS-restricted markets.
