Product details
Overview
ADR02BRZ-REEL7 from Analog Devices is a precision 5.0 V band gap voltage reference IC with ±0.1% initial accuracy, 3 ppm/°C typical temperature coefficient (A grade, SOIC), and 10 µVp-p low-frequency noise (0.1 Hz to 10 Hz). It operates from 7.0 V to 36.0 V input, delivers up to 10 mA output current, and functions across −40°C to +125°C for high-stability analog signal conditioning in data acquisition systems.
For engineers reviewing the ADR02BRZ-REEL7 datasheet, ADR02BRZ-REEL7 pinout, ADR02BRZ-REEL7 application, or ADR02BRZ-REEL7 equivalent, this page provides verified specifications, SC70-5 package mapping, TRIM/TEMP pin functionality, automotive-grade SOIC compatibility, and real-world design context for precision converter biasing and sensor excitation circuits.
Technical Context
The ADR02BRZ-REEL7 implements a band gap reference core with internal trimming and on-chip temperature sensing via the TEMP pin (550 mV baseline, 1.96 mV/°C sensitivity). Its TRIM pin enables fine adjustment of output voltage using an external resistor network, supporting calibration-critical applications.
It requires no external capacitor for stability, supports wide supply range operation (7.0 V–36.0 V), and maintains 40–70 ppm/mA load regulation over −40°C to +125°C. The device achieves 4 µs turn-on settling time and −75 dB ripple rejection at 10 kHz, enabling use in noisy industrial power environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.000 V nominal; tightly regulated for ADC/DAC reference rails requiring <±5 mV absolute error at 25°C. |
| Initial Accuracy | ±0.1% (±5 mV); enables single-point calibration in high-resolution (≥16-bit) data acquisition without post-trim. |
| Temp Coefficient | 3 ppm/°C typical (A grade, SOIC); ensures ≤±0.0375% output drift over −40°C to +125°C (±0.1875 mV). |
| Voltage Noise | 10 µVp-p (0.1 Hz–10 Hz); minimizes quantization uncertainty in 20+ bit sigma-delta converters. |
| Supply Range | 7.0 V to 36.0 V; accommodates unregulated industrial 12 V/24 V rails and battery-backed systems with wide voltage sag. |
| Output Current | 10 mA max; sufficient to drive SAR ADC references, op-amp bias networks, and low-power sensor bridges directly. |
| Operating Temp | −40°C to +125°C; qualified for under-hood automotive, motor control feedback, and industrial PLC modules. |
Pinout & Package
ADR02BRZ-REEL7 is supplied in a 5-lead SC70 surface-mount package (KS-5), footprint-compatible with TSOT-5. Pin 1 is marked by a dot; pinout is identical across ADR01/ADR02/ADR03/ADR06 SC70 variants.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Input supply connection | Accepts 7.0–36.0 V; dropout voltage is 2 V - minimum operating input is 7.0 V for 5.0 V output. |
| GND | Reference ground node | Must be low-impedance; separates analog reference return from digital/power grounds to preserve noise performance. |
| VOUT | Precision 5.0 V output | Delivers up to 10 mA; connects directly to ADC REF+ or instrumentation amplifier gain-setting networks. |
| TRIM | Output voltage adjustment terminal | Used with external resistor divider to calibrate output within ±0.5% - critical for metrology-grade systems. |
| TEMP | Temperature sensor output | Provides 550 mV @ 25°C with 1.96 mV/°C slope; enables on-chip thermal monitoring without external sensors. |
Key Features
| Feature | Design Value |
|---|---|
| No external capacitor required | Guaranteed stability with capacitive loads up to 100 nF - eliminates BOM cost and layout area for decoupling. |
| Ultracompact SC70 package | 1.25 mm × 2.1 mm footprint - enables placement adjacent to high-resolution ADCs in space-constrained PCBs. |
| Integrated temperature sensor | Monitors die temperature via TEMP pin (550 mV ±10 mV, 1.96 mV/°C) - supports thermal derating and system diagnostics. |
| Pin-compatible with REF02 | SOIC version (ADR02BRZ) replaces REF02 directly; SC70 version offers same functionality in 60% smaller area. |
| Automotive A-grade qualification | SOIC variant qualified per AEC-Q100 - suitable for engine control units, battery management, and ADAS sensor interfaces. |
Applications
| Industrial Process Control | Precision Data Acquisition |
|---|---|

Use Value: 50 ppm long-term stability (1000 hrs) ensures calibration validity between quarterly maintenance cycles. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| REF02CSZ-REEL7 | Same 5.0 V output, ±0.2% initial accuracy, 25 ppm/°C TC (SOIC only), no TEMP pin. | Lacks integrated temperature sensing and TRIM capability; lower accuracy limits use in metrology. | Select when cost sensitivity outweighs need for on-chip calibration or thermal monitoring. |
| ADR02ARZ-REEL7 | Identical specs but A grade (3 ppm/°C typical TC vs. B grade's 1–3 ppm/°C max); same SC70-5 package. | Higher tempco consistency across production lots - preferred for batch-critical calibration standards. | Choose for applications requiring guaranteed worst-case TC ≤3 ppm/°C, such as lab-grade instruments. |
Compared with REF02CSZ-REEL7, ADR02BRZ-REEL7 adds temperature sensing and trim capability at tighter initial accuracy; versus ADR02ARZ-REEL7, it trades guaranteed TC spec for lower cost while retaining identical noise, supply range, and footprint.

FAQ
What is the maximum load current supported by the ADR02BRZ-REEL7?
The ADR02BRZ-REEL7 delivers up to 10 mA of output current while maintaining specified accuracy and regulation. Load regulation is rated at 40–70 ppm/mA over −40°C to +125°C, meaning output voltage deviation remains within ±0.0005 V per mA of load change. Exceeding 10 mA may cause thermal overload or output droop beyond specification limits.
Does the ADR02BRZ-REEL7 require an input or output capacitor for stability?
No, the ADR02BRZ-REEL7 is internally compensated and requires no external capacitor for stability. It remains stable with capacitive loads up to 100 nF, as confirmed in the datasheet's transient response figures (e.g., Figure 31). Adding input or output capacitance is optional and used only for additional noise filtering or transient suppression - not for loop stability.
How is the TEMP pin used in the ADR02BRZ-REEL7?
The TEMP pin on the ADR02BRZ-REEL7 outputs a voltage proportional to die temperature: 550 mV at 25°C with a sensitivity of 1.96 mV/°C. It can be connected to an ADC input to monitor junction temperature for thermal derating or system diagnostics. No external components are needed - the output is ratiometric and calibrated across the full −40°C to +125°C range.
What is the dropout voltage specification for the ADR02BRZ-REEL7?
The ADR02BRZ-REEL7 has a fixed dropout voltage of 2 V, meaning it requires at least 7.0 V input to maintain a stable 5.0 V output. This value is constant across load and temperature, as shown in Figure 20 of the datasheet. Below 7.0 V input, regulation degrades rapidly - the device enters dropout and output follows input minus ~2 V.
Is the ADR02BRZ-REEL7 pin-compatible with industry-standard references?
The SOIC version (ADR02BRZ) is pin-compatible with REF02, including identical pinout and function mapping. However, the ADR02BRZ-REEL7 is in SC70-5 package - not pin-compatible with REF02's SOIC-8. For drop-in replacement in existing SOIC footprints, ADR02BRZ (not -REEL7) must be selected; the -REEL7 suffix denotes tape-and-reel packaging of the SC70 variant.
