Overview
The REF3325AIDBZTG4 is a fixed-output series voltage reference from Texas Instruments, providing a nominal output of 2.5V with an initial accuracy of ±0.15%. It operates within an input voltage range of 2.2V to 36V and draws a typical quiescent current of 3.9µA. The device features a temperature coefficient of 30ppm/°C and supports a maximum load current of 5mA. It is housed in a SOT-23-3 package and functions reliably across an extended industrial temperature range of -40°C to +125°C.
Feature Summary
- Ultra-low power consumption with 3.9µA supply current for battery-operated applications
- High precision stability with 30ppm/°C temperature coefficient and ±0.15% initial accuracy
- Compact surface-mount packaging options including SOT-23-3 and SC-70-3
Applications
- Portable instrumentation requiring low standby power
- Battery-powered measurement systems
- Data acquisition channels needing stable reference voltages
Procurement Notes
Verify the specific suffix 'G4' indicates lead-free compliance and RoHS status as per manufacturer documentation. Confirm the package type matches the design footprint, as this part number corresponds to the SOT-23-3 variant. Ensure the ordering quantity aligns with the specified reel or cut-tape packaging requirements defined in the official datasheet.
Selection Notes
Select this component when a 2.5V reference is required with minimal current draw. The 30ppm/°C drift specification suits applications where moderate thermal stability is acceptable. Compare against higher precision alternatives if tighter temperature coefficients are necessary for the target environment.
Part Context
This device belongs to the REF33xx family of nanopower voltage references designed for high efficiency. It shares architectural similarities with other members like the REF3312 and REF3320, differing primarily in output voltage and package availability. The family emphasizes low cost and small form factors for consumer electronics.
Replacement Considerations
Compatible substitutes include REF3325AIDCKR (SC-70-3 package) and REF3325AIRSER (UQFN-8 package). Verify pinout compatibility and thermal performance before substitution.
