Overview
The REF3320AIDBZR is a precision series voltage reference from Texas Instruments, delivering a fixed output of 2.048 V with an initial accuracy of 0.15%. It operates within a supply voltage range up to 5.5 V and draws a typical quiescent current of 3.9 uA. The device features a temperature coefficient of 30 ppm/C and supports a maximum shunt current of 5 mA. It is housed in a compact SOT-23-3 package and functions reliably across an extended industrial temperature range from -40°C to +125°C.
Feature Summary
- Provides stable series reference voltage with low temperature drift for high precision applications
- Ultra-low power consumption suitable for battery-operated systems
- Compact surface-mount packaging facilitates space-constrained designs
Applications
- Portable instrumentation requiring precise analog references
- Battery-powered measurement devices
- Data acquisition systems
Procurement Notes
Verify the specific suffix 'DBZR' indicates tape-and-reel packaging when ordering. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure moisture sensitivity level requirements are met during storage and handling procedures according to industry standards.
Selection Notes
Select this component when a 2.048 V output is required with tight initial accuracy and low thermal drift. Compare against other REF33xx variants if different voltage levels or higher current capabilities are needed. Consider the SOT-23-3 footprint constraints and verify input voltage headroom relative to the 5.5 V maximum limit.
Part Context
This part belongs to the REF3320 family of precision voltage references designed by Texas Instruments. It shares architectural similarities with other members like the REF3325 but differs in fixed output voltage. The series targets applications demanding stability and low power in small form factors.
Replacement Considerations
Check for direct pin-compatible alternatives within the same family, such as REF3325AIDBZR for different voltage needs. Verify electrical parameter compatibility before substituting with components from other manufacturers.
