Overview
The ADR425CR is an ultraprecision, low noise XFET voltage reference providing a fixed 5.00 V output. It features an initial accuracy of 0.12% and a temperature coefficient of 1 PPM/C. The device operates with a maximum input voltage of 18 V and draws 500 uA of supply current. It supports a maximum shunt current of 10 mA and functions within a temperature range of -40 C to +125 C. The component is housed in an 8-SOIC package.
Feature Summary
- Ultraprecision performance utilizing XFET technology for low noise operation
- High initial accuracy with minimal drift over temperature variations
- Low power consumption suitable for battery-operated systems
Applications
- Precision data acquisition systems
- Medical instrumentation
- Industrial process control
Procurement Notes
Verify the specific suffix against official Analog Devices documentation to confirm pinout and electrical characteristics match design requirements. Ensure the 8-SOIC package dimensions align with PCB layout constraints. Confirm RoHS compliance status through the manufacturer's latest release notes before finalizing procurement orders.
Selection Notes
Select this component when a stable 5 V reference with high accuracy is required. Compare the 1 PPM/C temperature coefficient against system thermal stability needs. Evaluate the 500 uA quiescent current against available power budgets. Consider the 8-SOIC footprint for surface mount assembly compatibility.
Part Context
This part belongs to the ADR425 series of XFET voltage references from Analog Devices. The series includes variants with different output voltages such as 2.048 V, 2.5 V, 3.0 V, and 5.0 V. All members share similar precision specifications and low-noise characteristics derived from the proprietary XFET architecture.
Replacement Considerations
Check for direct cross-references in Analog Devices' replacement guides. Verify that any substitute maintains the 8-SOIC package and 5 V output. Ensure equivalent temperature coefficients and accuracy levels are met for critical applications.
