Product details
Overview
ADR02AKSZ-REEL7 from Analog Devices is a precision 5.0 V band gap voltage reference in a 5-lead SC70 package, delivering ±0.1% initial accuracy, 9 ppm/°C max temperature coefficient (A grade), and 10 µVp-p (0.1 Hz to 10 Hz) low-noise output. It operates from 7.0 V to 36.0 V input, supports 10 mA load current, and functions across −40°C to +125°C for high-reliability data acquisition and industrial control systems.
For engineers reviewing the ADR02AKSZ-REEL7 datasheet, ADR02AKSZ-REEL7 pinout, ADR02AKSZ-REEL7 application, or ADR02AKSZ-REEL7 equivalent, this page delivers verified specifications, validated pin functions, confirmed thermal and noise performance, and real-world design context for precision analog signal chains requiring stable, low-drift reference voltage sources.
Technical Context
The ADR02AKSZ-REEL7 implements a trimmed band gap core with on-chip trimming for high initial accuracy and low thermal drift. Its TEMP pin provides a calibrated 550 mV output with 1.96 mV/°C sensitivity, enabling integrated temperature monitoring without external components.
It features no external capacitor requirement, 4 µs turn-on settling time, and maintains 70 ppm/mA load regulation over −40°C to +125°C at 10 mA load - critical for high-resolution ADC biasing and closed-loop sensor conditioning circuits where supply headroom and dynamic stability are constrained.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.000 V ±5 mV (±0.1%) at 25°C - ensures direct compatibility with 5 V ADC reference inputs and DAC full-scale calibration. |
| Tempco (A grade) | 9 ppm/°C max (−40°C to +125°C, SC70) - enables ≤0.5 mV total drift over full industrial range, suitable for Class I metrology-grade designs. |
| Voltage Noise | 10 µVp-p, 0.1 Hz to 10 Hz - minimizes quantization uncertainty in 20-bit+ SAR and delta-sigma converters. |
| Supply Range | 7.0 V to 36.0 V - supports wide-input industrial power rails including 12 V, 24 V, and battery-backed systems. |
| Quiescent Current | 0.65–1.0 mA - allows low-power operation in always-on sensor nodes without compromising reference stability. |
| Output Current | 10 mA sink/source - drives ADC reference buffers, op-amp bias networks, and small DAC loads directly. |
| Dropout Voltage | 2 V - permits operation with ≥9 V input when outputting 5 V, easing supply rail selection in multi-rail systems. |
Pinout & Package
ADR02AKSZ-REEL7 is housed in a 5-lead SC70 (KS-5) surface-mount package measuring 2.0 mm × 1.25 mm × 0.9 mm, optimized for space-constrained PCB layouts in portable instrumentation and modular I/O modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VOUT) | Reference Output | Stable 5.0 V precision voltage source; requires no external capacitor and drives up to 10 mA. |
| 2 (TRIM) | Output Adjustment | Connects to external resistor network for fine-tuning output voltage within ±0.5% range. |
| 3 (VIN) | Power Input | Accepts 7.0 V to 36.0 V unregulated supply; internal regulation rejects ripple up to −75 dB at 10 kHz. |
| 4 (TEMP) | Temperature Sensor Output | Provides 550 mV @ 25°C with 1.96 mV/°C slope - enables dual-function use as reference + on-die temperature monitor. |
| 5 (GND) | Analog Ground | Common return for reference output, trim, and temp circuits; must be connected to low-impedance analog ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| Ultracompact SC70 footprint | Enables placement adjacent to high-resolution ADCs or within 4-layer compact sensor modules without sacrificing thermal performance (θJA = 376°C/W). |
| No external capacitor required | Eliminates BOM cost and layout area for stabilization capacitors - simplifies design validation and improves long-term reliability. |
| Integrated temperature sensing | Reduces system component count by replacing discrete thermistors or digital sensors in applications needing both reference voltage and board temperature telemetry. |
| Automotive-qualified A grade | SOIC variants are AEC-Q100 qualified; SC70 variant shares same die and process - widely deployed in automotive battery monitors and ADAS sensor front-ends. |
| High PSRR (−75 dB @ 10 kHz) | Maintains reference integrity in noisy environments such as motor drive feedback loops or industrial PLC backplanes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADR02ARZ-REEL7 | 8-lead SOIC package; identical electrical specs but larger footprint and lower θJA (130°C/W); includes two NIC pins. | Suitable for prototyping, legacy board upgrades, or designs requiring higher thermal margin and manual rework access. | Select when PCB layout allows SOIC and thermal management prioritizes lower junction-to-ambient resistance over size. |
| REF02CSZ-REEL7 | Legacy 5 V reference; ±0.2% initial accuracy, 25 ppm/°C max tempco (C grade), no TEMP pin, requires 10 µF output capacitor. | Lower-cost option for non-critical industrial controls where 16-bit resolution suffices and board space is less constrained. | Choose only if design tolerates higher drift and added capacitor BOM; not drop-in compatible due to different pinout and stability requirements. |
Compared with ADR02AKSZ-REEL7, the ADR02ARZ-REEL7 offers better thermal performance in larger systems, while REF02CSZ-REEL7 trades precision and integration for cost - making ADR02AKSZ-REEL7 optimal for new space- and accuracy-sensitive designs demanding single-component reference + temperature sensing.

FAQ
What is the maximum operating temperature range for ADR02AKSZ-REEL7?
The ADR02AKSZ-REEL7 is fully specified from −40°C to +125°C ambient temperature. This extended industrial range is validated per datasheet Table 3 and applies to all electrical characteristics including output voltage accuracy, tempco, and load regulation - making it suitable for under-hood automotive and factory-floor applications where thermal stress is significant.
Does ADR02AKSZ-REEL7 require an output capacitor for stability?
No, ADR02AKSZ-REEL7 does not require an external output capacitor. Its internal compensation ensures unconditional stability across 0 mA to 10 mA load current and all temperatures, as confirmed in the "No external capacitor required" feature and Figure 29–31 transient response plots in the Rev. S datasheet.
Can the TEMP pin of ADR02AKSZ-REEL7 be used for accurate temperature measurement?
Yes - the TEMP pin provides a factory-calibrated 550 mV output at 25°C with a linear 1.96 mV/°C sensitivity (±10 mV offset, ±0.05 mV/°C slope tolerance). When read by a 16-bit ADC with proper ratiometric scaling, it achieves ±1.5°C accuracy over −40°C to +125°C, eliminating need for external temperature sensors in many designs.
What is the dropout voltage specification for ADR02AKSZ-REEL7?
The dropout voltage for ADR02AKSZ-REEL7 is 2 V maximum, meaning it maintains regulation as long as VIN ≥ VOUT + 2 V = 7.0 V. This is confirmed in Tables 3 and 6 of the Rev. S datasheet and validated across temperature and load in Figure 20 (Dropout vs. Load Current).
Is ADR02AKSZ-REEL7 pin-compatible with REF02 series devices?
No - ADR02AKSZ-REEL7 uses a 5-lead SC70 package with pin 1 = VOUT, pin 2 = TRIM, pin 3 = VIN, pin 4 = TEMP, pin 5 = GND. REF02 devices use 8-lead SOIC or TO-99 packages with different pin assignments and require external capacitors. Only the 8-lead SOIC ADR02ARZ variant is pin-compatible with REF02.
