Product details
Overview
ADR01BRZ-REEL7 from Analog Devices is a precision 10.0 V band gap voltage reference IC with ±0.05% initial accuracy (B grade), 1–3 ppm/°C temperature coefficient in 8-lead SOIC package, and −40°C to +125°C operating range. It delivers stable 10.0 V output across 12.0 V to 36.0 V input, supports 10 mA load current, and integrates TEMP and TRIM pins for temperature monitoring and fine output adjustment-used in high-resolution ADC biasing and industrial process control.
For engineers reviewing the ADR01BRZ-REEL7 datasheet, ADR01BRZ-REEL7 pinout, ADR01BRZ-REEL7 application, or ADR01BRZ-REEL7 equivalent, this page provides verified specifications, SOIC-8 pin mapping, real-world use cases in precision data acquisition and auto battery monitoring, and two validated alternative parts with documented technical and application differences.
Technical Context
The ADR01BRZ-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 B-grade specification targets high-stability applications requiring ≤3 ppm/°C drift over −40°C to +125°C.
It operates without external capacitors, features 70 ppm/mA load regulation and 7–30 ppm/V line regulation, and maintains 20 µVp-p (0.1 Hz–10 Hz) noise performance. The device supports drop-in replacement for REF01 in 8-lead SOIC layouts while adding temperature monitoring capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 10.000 V ±0.05% (B grade) - enables direct interface with 16-bit+ SAR ADCs without gain calibration |
| Tempco | 1–3 ppm/°C (B grade, SOIC) - ensures <±0.3 mV drift over full industrial temperature range |
| Initial Accuracy | ±0.05% (±5 mV) - reduces system-level offset error in precision sensor signal chains |
| Supply Range | 12.0 V to 36.0 V - compatible with unregulated industrial 24 V rails and automotive battery inputs |
| Output Current | 10 mA - drives multiple op-amp references or ADC reference inputs simultaneously |
| Voltage Noise | 20 µVp-p (0.1 Hz–10 Hz) - avoids noise-induced quantization errors in low-frequency measurement systems |
| Quiescent Current | 0.65–1.0 mA - enables low-power operation in always-on industrial monitoring nodes |
Pinout & Package
ADR01BRZ-REEL7 is supplied in an 8-lead SOIC (R-8) package with standard JEDEC MS-012AC footprint (5.0 mm × 6.2 mm, 1.27 mm pitch). Thermal resistance θJA = 130°C/W under typical PCB layout conditions.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VOUT | 10.0 V regulated output - connects directly to ADC REFIN, DAC reference, or op-amp feedback network |
| 2 | NIC | No internal connection - left floating or grounded per layout best practice; no circuit function |
| 3 | TRIM | Fine-adjustment node - used with external resistor divider to calibrate output within ±0.1% window |
| 4 | NIC | No internal connection - unused pin; no electrical or thermal role |
| 5 | NIC | No internal connection - unused pin; no electrical or thermal role |
| 6 | VIN | Input supply (12–36 V) - requires local 0.1 µF ceramic decoupling per datasheet recommendation |
| 7 | TEMP | Temperature-sensing output (550 mV @ 25°C, 1.96 mV/°C) - enables on-chip thermal monitoring without external sensor |
| 8 | GND | Analog ground reference - must be connected to clean system AGND plane with low-impedance path |
Key Features
| Feature | Design Value |
|---|---|
| Pin-compatible REF01 replacement | SOIC-8 footprint matches REF01 with identical pin 1–8 assignment; adds TEMP functionality without PCB redesign |
| Integrated temperature sensor | TEMP pin provides factory-calibrated analog voltage (550 mV ±10 mV at 25°C) for system thermal diagnostics |
| No external capacitor required | Stable operation with zero external capacitance simplifies layout and eliminates capacitor aging/tolerance risks |
| B-grade low tempco | 1–3 ppm/°C max drift over −40°C to +125°C enables high-accuracy operation in harsh environments |
| Automotive-qualified A grade option | ADR01WARZ variant qualified per AEC-Q100; ADR01BRZ-REEL7 is industrial-grade but shares same SOIC reliability structure |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| REF01CSZ-REEL7 | Same 10 V output, ±0.1% initial accuracy, no TEMP pin, 25 ppm/°C tempco (C grade) | Lacks temperature sensing; higher drift limits use in wide-temp industrial systems | Select when TEMP functionality is unnecessary and cost is primary driver |
| ADR01ARZ-REEL7 | Same 10 V output, ±0.1% initial accuracy, 3–10 ppm/°C tempco (A grade), identical pinout | Looser initial tolerance and higher tempco than B grade; suitable for less demanding applications | Select when 3 ppm/°C max drift is acceptable and tighter initial accuracy is not required |
Compared with REF01CSZ-REEL7, ADR01BRZ-REEL7 adds temperature monitoring and cuts tempco by >8×; compared with ADR01ARZ-REEL7, it improves initial accuracy by 2× and reduces worst-case drift by 3×-justifying B grade selection for metrology-grade designs.
