Product details
Overview
ADR02WARZ-REEL from Analog Devices is a precision 5.0 V band gap voltage reference IC with ±0.1% initial accuracy, 9 ppm/°C max temperature coefficient (5-lead SC70 package), 10 µVp-p low-frequency noise (0.1 Hz to 10 Hz), and −40°C to +125°C operating range. It delivers stable 5.0 V output for high-resolution ADCs, industrial process controllers, and auto battery monitoring circuits requiring minimal drift and no external capacitor.
For engineers reviewing the ADR02WARZ-REEL datasheet, ADR02WARZ-REEL pinout, ADR02WARZ-REEL application, or ADR02WARZ-REEL equivalent, this page provides verified specifications, validated SC70 pin mapping, real-world use cases in precision data acquisition and automotive sensing, and two confirmed alternative parts with documented functional and packaging differences.
Technical Context
The ADR02WARZ-REEL implements a band gap reference core with integrated TEMP and TRIM terminals, enabling on-board temperature monitoring (550 mV baseline, 1.96 mV/°C sensitivity) and fine output adjustment. Its architecture supports operation from 7.0 V to 26.0 V input with 2 V dropout and delivers up to 10 mA load current while maintaining ≤70 ppm/mA load regulation over full temperature range.
It features ultra-low 10 µVp-p noise in the 0.1 Hz–10 Hz band and −75 dB ripple rejection at 10 kHz, making it suitable for metrology-grade signal chains. The device requires no external stabilization capacitors and achieves 4 µs turn-on settling time, supporting fast power-up sequences in embedded systems.

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-REEL | Same 5.0 V output and SC70 package, but A grade (3 ppm/°C typical TC, 8-lead SOIC only); ADR02WARZ-REEL is W grade in SC70 with 9 ppm/°C max TC. | SOIC version requires larger PCB area; not drop-in for SC70 footprints. | Select ADR02ARZ-REEL only if lower TC is critical and SOIC layout is acceptable. |
| REF02CSZ-REEL7 | 5.0 V reference with 10 ppm/°C max TC, 8-lead SOIC, requires 1 µF output capacitor for stability. | Larger package and capacitor dependency increase BOM count and layout complexity. | Choose REF02CSZ-REEL7 only when legacy REF02 compatibility is required in SOIC designs. |
Compared with ADR02ARZ-REEL and REF02CSZ-REEL7, the ADR02WARZ-REEL uniquely combines SC70 size, capacitor-free operation, and guaranteed 9 ppm/°C max TC-making it optimal for miniaturized, low-component-count precision systems where board space and design simplicity are prioritized over ultra-low TC.

FAQ
What is the maximum input voltage rating for ADR02WARZ-REEL?
The ADR02WARZ-REEL has an absolute maximum supply voltage of 36.0 V, but its specified operating range is 7.0 V to 26.0 V. Exceeding 26.0 V may degrade long-term stability or violate thermal limits, especially in the SC70 package with θJA = 376°C/W. Always maintain VIN ≤26.0 V for reliable operation per datasheet conditions.
Does ADR02WARZ-REEL require an output capacitor for stability?
No, the ADR02WARZ-REEL is internally compensated and does not require an external output capacitor for stability. This eliminates potential phase-margin issues and reduces bill-of-materials cost. However, a 0.1 µF ceramic capacitor placed close to the VOUT pin is recommended for high-frequency noise suppression in noisy environments.
How is the TEMP pin used in ADR02WARZ-REEL?
The TEMP pin on ADR02WARZ-REEL outputs 550 mV at 25°C with a linear sensitivity of 1.96 mV/°C, enabling direct die temperature measurement. It can be connected to an ADC input for thermal monitoring or used in feedback loops to compensate for temperature-induced gain/offset drift in downstream circuitry without adding discrete sensors.
What is the load regulation performance of ADR02WARZ-REEL?
The ADR02WARZ-REEL exhibits ≤70 ppm/mA load regulation over −40°C to +125°C at VIN = 10.0 V, translating to ≤0.35 mV change in output voltage across a 0–10 mA load. This ensures consistent reference accuracy even when driving multiple loads like op-amp bias networks or ADC reference buffers simultaneously.
Is ADR02WARZ-REEL pin-compatible with REF02?
No-ADR02WARZ-REEL uses a 5-lead SC70 package with pins VOUT, TRIM, VIN, TEMP, GND, whereas REF02 is offered only in 8-lead SOIC with different pinout and no TEMP function. While ADR02ARZ (SOIC) is pin-compatible with REF02, the SC70 ADR02WARZ-REEL is not a mechanical or electrical drop-in replacement for REF02.
