Overview
The ADR4533ARZ-R7 is a series precision voltage reference providing a fixed 3.3 V output in an 8-lead SOIC package. It features a maximum initial accuracy of ±0.04% and a temperature coefficient of 2 ppm/°C over the -40°C to +125°C range. The device operates with a supply voltage between 3.4 V and 15 V, drawing a maximum quiescent current of 950 μA. It supports up to 10 mA sourcing and sinking current with a typical low dropout voltage of 100 mV at no load.
Feature Summary
- Ultra-low noise performance for high-resolution signal processing
- High stability with minimal long-term drift and thermal hysteresis
- Low power consumption suitable for portable equipment
Applications
- Precision data acquisition systems
- High resolution data converters
- Industrial instrumentation
- Medical devices
Procurement Notes
Verify the specific grade (B or A) required for your application, as the base part number covers multiple accuracy levels. Confirm that the -R7 suffix matches your manufacturing needs for reel packaging. Ensure input voltage exceeds the minimum operating threshold of 3.4 V to maintain regulation. Check RoHS compliance status before finalizing procurement orders.
Selection Notes
Select this component when a stable 3.3 V reference is needed with strict noise and drift requirements. Compare against other grades if tighter temperature coefficients are necessary. Consider the 8-lead SOIC footprint constraints during PCB layout. Evaluate the 950 μA quiescent current against system power budgets.
Part Context
This device belongs to the ADR45xx family of ultralow noise, high accuracy voltage references from Analog Devices. The family includes various output voltages such as 2.048 V, 2.5 V, 3.0 V, 4.096 V, and 5.0 V. All members share similar architectural benefits including innovative core topology for improved stability.
Replacement Considerations
ADR4533ARZ is the tube-packaged equivalent of the same electrical specification.
FAQ
What is the maximum output current capability?
The device can source up to 10 mA and sink up to 10 mA.
Does the ADR4533 support Kelvin sensing connections?
No, the 8-lead SOIC package does not include dedicated Force and Sense pins; those are available in the LCC package variant.
