Product details
Overview
ADR06AKS-R2 from Analog Devices is a precision 3.0 V band gap voltage reference IC in a 5-lead SC70 package, featuring ±0.2% initial accuracy, 9 ppm/°C max temperature coefficient (A grade), and 6 µVp-p (0.1 Hz to 10 Hz) low-noise output. It delivers stable 3.0 V reference voltage across −40°C to +125°C for high-resolution ADCs and industrial sensor signal chains.
For engineers reviewing the ADR06AKS-R2 datasheet, ADR06AKS-R2 pinout, ADR06AKS-R2 application, or ADR06AKS-R2 equivalent, this page provides verified electrical specs, thermal performance data, SC70 pin mapping, automotive-grade qualification status, and validated alternative options for precision analog design.
Technical Context
The ADR06AKS-R2 uses a proprietary band gap core with on-chip trimming to achieve tight initial accuracy and low drift over temperature. Its TEMP pin provides a calibrated 550 mV output with 1.96 mV/°C sensitivity for external temperature monitoring, while the TRIM pin allows fine adjustment of the 3.0 V output via external resistor network.
Designed for wide-input operation (5.0 V to 36.0 V), it maintains 10 mA output current capability with only 2 V dropout and no external capacitor required. The device supports high PSRR (−75 dB at 10 kHz) and exhibits 50 ppm long-term stability over 1000 hours.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 3.000 V nominal; 2.994 V to 3.006 V (A/C grade) - ensures <±2 mV absolute error in precision DAC/ADC biasing |
| Initial Accuracy | ±0.2% (±6 mV) - enables single-point calibration in 16-bit systems without trimming |
| Temp Coefficient | 9 ppm/°C max (A grade, SC70) - contributes ≤108 ppm error over −40°C to +125°C span |
| Voltage Noise | 6 µVp-p, 0.1 Hz–10 Hz - limits noise floor in 24-bit delta-sigma converters |
| Supply Range | 5.0 V to 36.0 V - supports direct connection to unregulated 12 V/24 V industrial rails |
| Quiescent Current | 0.65–1.0 mA - enables low-power battery-operated instrumentation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADR02AKS-R2 | 5.0 V output, same SC70 package, identical pinout and temp sensor functionality | Used where system requires 5.0 V reference instead of 3.0 V; not interchangeable without schematic change | Select when higher reference voltage improves ADC dynamic range or matches legacy 5 V analog subsystems |
| REF3030AIDBZR | 3.0 V output, SOT-23-3 package, 10 ppm/°C max TC, 25 µVp-p noise, no TEMP/TRIM pins | Lacks temperature monitoring and output trimming; simpler but less flexible in multi-function designs | Choose for cost-sensitive, space-constrained applications where only basic 3.0 V reference is needed |
Compared with ADR06AKS-R2, ADR02AKS-R2 offers identical architecture at 5.0 V output-ideal for voltage-scaling upgrades-while REF3030AIDBZR trades TEMP/TRIM capability and lower noise for lower cost and smaller 3-pin footprint.

FAQ
What is the maximum input voltage rating for ADR06AKS-R2?
The ADR06AKS-R2 has an absolute maximum supply voltage of 36.0 V. Its specified operating range is 5.0 V to 36.0 V, enabling direct use with common industrial 12 V and 24 V rails. Operation above 36.0 V risks permanent damage per Absolute Maximum Ratings table in the Rev. S datasheet.
Does ADR06AKS-R2 require an external output capacitor?
No, the ADR06AKS-R2 is internally compensated and does not require an external output capacitor for stability. This simplifies layout and eliminates capacitor-related drift or aging effects. However, a small ceramic capacitor (e.g., 100 nF) may be added at VOUT for additional high-frequency noise filtering if system-level testing indicates benefit.
Can the TEMP pin of ADR06AKS-R2 be used for accurate temperature measurement?
Yes-the TEMP pin provides a factory-calibrated 550 mV output at 25°C with a linear sensitivity of 1.96 mV/°C across −40°C to +125°C. When interfaced with a ratiometric ADC, it enables ±1.5°C typical accuracy for ambient temperature monitoring without external calibration components.
What is the dropout voltage specification for ADR06AKS-R2?
The ADR06AKS-R2 has a dropout voltage of 2 V maximum across temperature and load conditions. At 10 mA output current and +125°C, measured dropout remains ≤2.0 V, meaning VIN must be ≥5.0 V to maintain regulated 3.0 V output-consistent with its 5.0 V minimum supply rating.
Is ADR06AKS-R2 qualified for automotive applications?
Yes-ADR06AKS-R2 is offered in A grade and qualified to AEC-Q100 Grade 1 standards (−40°C to +125°C junction temperature), making it suitable for automotive body electronics, battery monitoring, and powertrain auxiliary sensing applications where extended temperature reliability is mandatory.
