ADR293TRU-EP-R7

Overview

The ADR293TRU-EP-R7 is a low noise, micropower precision voltage reference from Analog Devices Inc., utilizing XFET architecture. It provides a fixed 5.0 V output with an initial accuracy of 0.2% and a maximum temperature coefficient of 30 ppm/°C over the military range of -55°C to +125°C. The device operates on a supply voltage between 6.0 V and 15 V, drawing a maximum quiescent current of 15 μA at 25°C. It features a typical 0.1 Hz to 10 Hz noise of 15 μV p-p and supports up to 5 mA load current. Packaged in an 8-lead TSSOP (RU-8) in reel format.

Feature Summary

• Utilizes XFET architecture for ultralinear temperature drift and low thermal hysteresis
• Supports defense and aerospace applications under AQEC standards
• Features controlled manufacturing baseline with single assembly and fabrication sites

Applications

• Portable instrumentation
• Precision reference for 5 V systems
• ADC and DAC reference
• Solar-powered applications

Procurement Notes

Verify the specific ordering suffix to confirm packaging type; the -R7 suffix indicates reel packaging. Confirm RoHS compliance status via the Z suffix if required. Ensure the military temperature grade (-55°C to +125°C) matches system requirements. Check for available qualification data requests for aerospace or defense procurement protocols.

Selection Notes

Select this component when a stable 5 V reference is needed with ultra-low noise characteristics. The XFET technology offers superior performance compared to traditional bandgap references at similar currents. Consider the 15 μA supply current for battery-operated designs. Verify that the 6.0 V minimum supply voltage aligns with the system power rails.

Part Context

This part belongs to the ADR293-EP series, which are enhanced product versions designed for high-reliability environments. The EP designation signifies adherence to strict quality controls, including controlled manufacturing baselines and product change notifications suitable for long-term production stability.

Replacement Considerations

Pin-compatible with REF02 and REF19x series devices. Direct substitution requires verifying supply voltage compatibility and ensuring the replacement meets the required noise and temperature coefficient specifications.
