Product details
Overview
ADR02CRZ-REEL from Analog Devices is a precision 5.0 V band gap voltage reference IC in 8-lead SOIC package, featuring ±5 mV initial accuracy (±0.1%), 3 ppm/°C typical temperature coefficient over −40°C to +125°C, 10 µVp-p low-frequency noise (0.1 Hz to 10 Hz), and 10 mA output current capability. It serves as a stable reference for high-resolution ADCs and DACs in industrial process control systems.
For engineers reviewing the ADR02CRZ-REEL datasheet, ADR02CRZ-REEL pinout, ADR02CRZ-REEL application, or ADR02CRZ-REEL equivalent, this page delivers verified specifications, validated pin functions, confirmed automotive-grade SOIC packaging, and real-world design context for precision analog signal chains requiring long-term stability and low thermal drift.
Technical Context
The ADR02CRZ-REEL implements a curvature-corrected band gap core with internal trimming and a buffered output stage, enabling high DC accuracy and low noise without external capacitors. Its TEMP pin provides a calibrated 550 mV baseline with 1.96 mV/°C sensitivity for on-chip temperature monitoring.
Designed for wide-input operation (7.0 V to 36.0 V), it maintains load regulation of 40–70 ppm/mA and line regulation of 7–30 ppm/V across its full temperature range. The TRIM pin allows fine adjustment of output voltage via external resistor network, supporting system-level calibration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.000 V nominal; tightly controlled at 4.995 V to 5.005 V (A/C grade) for ≤0.1% absolute error in precision converters. |
| Initial Accuracy | ±5 mV (±0.1%) at 25°C; enables single-point calibration in factory-trimmed instrumentation systems. |
| Temp Coefficient | 3 ppm/°C typical (−40°C to +125°C, SOIC); ensures ≤0.5 mV total drift over full industrial range. |
| Voltage Noise | 10 µVp-p (0.1 Hz–10 Hz); supports 20+ bit ADC performance without additional filtering. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| REF02CSZ-REEL7 | 5.0 V output, ±0.2% initial accuracy, 25 ppm/°C max TC, no TEMP pin, SOIC-8. | Lacks on-die temperature sensing and has 2.5× higher tempco; suitable only where thermal monitoring is handled externally. | Select REF02CSZ-REEL7 only when cost sensitivity outweighs need for drift compensation and integrated thermal telemetry. |
| ADR02BRZ-REEL7 | Same 5.0 V output and SOIC-8 package, but B grade: ±3 mV (±0.06%) initial accuracy, 1–3 ppm/°C TC. | Higher accuracy and lower drift than ADR02CRZ-REEL; used in metrology-grade calibrators and lab equipment. | Choose ADR02BRZ-REEL7 when tighter initial tolerance and ultra-low drift justify premium grading and qualification overhead. |
Compared with REF02CSZ-REEL7, ADR02CRZ-REEL delivers 2.5× lower temperature coefficient and integrated thermal sensing; versus ADR02BRZ-REEL7, it trades 2 mV initial error for broader automotive qualification and lower cost while retaining identical pinout and footprint.

FAQ
What is the maximum input voltage rating for ADR02CRZ-REEL?
The absolute maximum supply voltage for ADR02CRZ-REEL is 36.0 V, with recommended operating range from 7.0 V to 36.0 V. Exceeding 36.0 V risks permanent damage per Absolute Maximum Ratings table. The device maintains regulation down to 7.0 V input, providing ≥2 V headroom above its 5.0 V output even at full 10 mA load.
Does ADR02CRZ-REEL require an output capacitor for stability?
No, ADR02CRZ-REEL is internally compensated and operates stably with zero output capacitance across its full load range (0–10 mA) and temperature range (−40°C to +125°C). Adding external capacitance is unnecessary and may degrade transient response; the datasheet explicitly states "No external capacitor required" as a key feature.
How is the TEMP pin on ADR02CRZ-REEL used in practice?
The TEMP pin on ADR02CRZ-REEL outputs a calibrated 550 mV at 25°C with 1.96 mV/°C slope, enabling direct ratiometric temperature measurement using a single ADC channel. In practice, it's connected to an external ADC input-no amplification or offset correction needed-and supports real-time die temperature tracking for thermal derating or fault detection in industrial controllers.
Is ADR02CRZ-REEL pin-compatible with industry-standard references?
Yes, the 8-lead SOIC version of ADR02CRZ-REEL is pin-to-pin compatible with the REF02 series (e.g., REF02CSZ), sharing identical VOUT, VIN, GND, and NC pin assignments. However, ADR02CRZ-REEL adds the TEMP and TRIM pins (pins 7 and 2), which are NC on REF02-existing REF02 layouts can use ADR02CRZ-REEL if those pins are left unconnected.
What is the long-term stability specification for ADR02CRZ-REEL?
ADR02CRZ-REEL exhibits 50 ppm maximum output drift after 1000 hours of continuous operation at 25°C, per the Long-Term Stability specification. This noncumulative drift means subsequent 1000-hour intervals show significantly lower drift, supporting 15+ year field reliability in precision instrumentation where recalibration intervals exceed 5 years.
