Overview
The ADR293GRZ is a low noise, micropower precision voltage reference providing a fixed 5.0 V output. It operates within a supply range of 6.0 V to 15 V with a maximum supply current of 15 μA. The device features an initial accuracy of ±0.20% and a maximum temperature coefficient of 25 ppm/°C. It delivers up to 5 mA of load current and exhibits typical voltage noise of 15 μV p-p from 0.1 Hz to 10 Hz. The component functions reliably across an extended industrial temperature range of −40°C to +125°C.
Feature Summary
- Utilizes XFET architecture for ultralinear temperature drift and low thermal hysteresis.
- Provides high output current capability of 5 mA while maintaining micropower consumption.
- Offers pin compatibility with REF02 and REF19x series references.
Applications
- Portable instrumentation
- Precision reference for 5 V systems
- ADC and DAC reference
- Solar-powered applications
Procurement Notes
Verify the specific suffix (e.g., GRZ) against the manufacturer's ordering guide to confirm package type and RoHS compliance status. Ensure the required electrical grade matches the design specifications for initial accuracy and temperature coefficient. Confirm availability through authorized distributors as stock levels may vary.
Selection Notes
Select this component when a stable 5 V reference is required in battery-powered or portable designs due to its low quiescent current. Consider the 8-lead SOIC package for standard surface mount assembly. Evaluate line and load regulation requirements against the specified limits for the G-grade variant.
Part Context
The ADR293 belongs to the ADR29x family of XFET-based voltage references manufactured by Analog Devices. This family includes variants with different output voltages such as 2.5 V and 4.096 V. The GRZ designation specifically identifies the 5.0 V version packaged in an 8-lead Narrow Body SOIC format.
Replacement Considerations
Pin-compatible replacements include the REF02 and REF19x series. Verify that substitute components meet the specific 5.0 V output requirement and match the thermal and electrical performance characteristics of the original design.
