ADR06AR

Overview

The ADR06AR is a precision band gap voltage reference providing a nominal 3.0 V output in an 8-lead SOIC package. It operates from a supply voltage range of 5.0 V to 36.0 V with a maximum shunt current of 10 mA and quiescent current of 0.65 mA. The device features an initial accuracy of ±0.2% for C grade and ±0.1% for B grade, with a temperature coefficient of 10 ppm/°C (typical) for A grade. It functions within an extended industrial temperature range of −40°C to +125°C.

Feature Summary

• Provides stable 3.0 V reference output without requiring external capacitors
• Includes a dedicated TEMP pin for temperature sensing applications
• Features a TRIM pin for fine adjustment of the output voltage
• Supports wide input voltage ranges up to 36.0 V

Applications

• Precision data acquisition systems
• High resolution converters
• Industrial process control systems
• Auto battery monitoring

Procurement Notes

Verify the specific grade (A, B, or C) required for your application, as accuracy and temperature coefficient specifications vary significantly between grades. Confirm that the 8-lead SOIC package aligns with your PCB footprint requirements. Ensure the input voltage remains within the 5.0 V to 36.0 V operational window to maintain specified performance levels.

Selection Notes

Select the ADR06AR when a compact, high-stability 3.0 V reference is needed in space-constrained designs. Choose this component over other series members if the 3.0 V output level is optimal for your ADC or DAC inputs. Consider the A grade for automotive qualification or lower drift requirements, while B or C grades offer cost-effective solutions for general-purpose instrumentation.

Part Context

The ADR06AR belongs to the ADR01/ADR02/ADR03/ADR06 family of ultracompact precision voltage references. This series includes 10.0 V, 5.0 V, 2.5 V, and 3.0 V variants, all sharing similar architectural features such as low noise and wide operating ranges. The ADR06 specifically targets applications requiring a 3.0 V reference standard.

Replacement Considerations

The SOIC versions of the ADR01, ADR02, and ADR03 are drop-in replacements for industry-standard REF01, REF02, and REF03 respectively. However, the ADR06 does not have a direct legacy pin-compatible replacement listed in the documentation. Verify thermal resistance and pinout compatibility if substituting with other voltage references.
