Product details
Overview
ADR292GRZ-REEL7 from Analog Devices is a low-noise, micropower precision voltage reference delivering a stable 4.096 V output with ±3 mV (±0.07%) initial accuracy, 8 ppm/°C max temperature coefficient (E grade), and 12 μVp-p (0.1 Hz to 10 Hz) noise. It operates from 4.4 V to 15 V supply, draws ≤15 μA quiescent current, and supports 5 mA output current - ideal for high-resolution ADC/DAC references in battery-powered instrumentation.
For engineers reviewing the ADR292GRZ-REEL7 datasheet, ADR292GRZ-REEL7 pinout, ADR292GRZ-REEL7 application, or ADR292GRZ-REEL7 equivalent, this page provides verified specifications, SOIC-8 package details, real-world use cases in portable data acquisition and solar-powered sensors, and two validated alternative parts with documented technical and application differences.
Technical Context
The ADR292GRZ-REEL7 uses Analog Devices' XFET® architecture - a junction FET-based reference topology that replaces traditional bandgap or buried Zener circuits. This delivers ultralow thermal hysteresis (50 ppm), excellent long-term stability (50 ppm after 1000 h at 125°C), and inherently low noise due to minimal PTAT correction circuitry.
It functions as a series-shunt voltage reference with internal vertical PNP output transistors enabling low dropout operation. The device is specified across −40°C to +125°C, supports Kelvin sensing, and maintains load regulation of ≤100 ppm/mA and line regulation of ≤100 ppm/V over its full operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 4.096 V nominal; tight tolerance enables direct interface with 12-bit and 16-bit SAR/Σ-Δ ADCs using 4.096 V full-scale range. |
| Initial Accuracy | ±3 mV (±0.07%) - meets E-grade spec; eliminates need for system-level trimming in portable medical or sensor nodes. |
| Temp Coefficient | 8 ppm/°C max (E grade); ensures <±0.5 mV drift over −40°C to +85°C - critical for uncalibrated field instruments. |
| Noise (0.1–10 Hz) | 12 μVp-p; enables <16-bit effective resolution without external filtering in precision data loggers. |
| Supply Current | 12 μA typ / 15 μA max at 125°C; extends battery life >10 years in solar-powered remote sensors with 10 μA sleep budgets. |
| Load Current | 5 mA sourcing capability; drives ADC reference inputs, op-amp bias networks, and small DAC buffers without external gain stages. |
| Operating Temp | −40°C to +125°C; qualified for under-hood automotive sensors, industrial PLC I/O modules, and downhole oilfield tools. |
Pinout & Package
ADR292GRZ-REEL7 is supplied in an 8-lead SOIC_N (R-8) package per JEDEC MS-012-AA, with 1.27 mm lead pitch, 5.00 mm × 4.00 mm body, and gull-wing leads. Pin 1 marked by notch or bevel; NC pins are internally reserved and must remain unconnected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 7, 8 | NC | No internal connection; floating terminals - must be left unconnected to avoid parasitic coupling or latch-up risk. |
| 2 | VIN | Input supply node; requires ≥4.4 V minimum; dropout voltage is ~0.7 V at 5 mA load - dictates minimum system rail design. |
| 4 | GND | Analog ground reference; must tie directly to low-impedance system AGND plane - separate from digital ground to preserve PSRR. |
| 6 | VOUT | Precision 4.096 V output; bypass with 0.1 μF ceramic + 10 μF tantalum per datasheet Figure 32 to suppress broadband noise and load transients. |
Key Features
| Feature | Design Value |
|---|---|
| XFET® Reference Core | Delivers ¼ the noise of bandgap references at same current; enables sub-μV p-p noise floor in 16-bit+ measurement systems. |
| Low Thermal Hysteresis | 50 ppm typical; ensures repeatable output after thermal cycling - essential for calibration-critical lab equipment and metrology tools. |
| High Output Current | 5 mA sourcing capacity; eliminates need for external buffer op-amps when driving multiple ADC references or precision DACs. |
| Extended Temperature Range | Specified from −40°C to +125°C; supports operation in harsh environments including automotive engine control units and industrial motor drives. |
| Pin Compatibility | Direct replacement for REF02 and REF19x families; allows drop-in upgrade path in legacy designs without PCB revision. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADR292ARZ-REEL7 | Same electrical specs but A-grade (±4 mV initial accuracy, 15 ppm/°C TC); identical SOIC-8 package and pinout. | Lower accuracy grade suits cost-sensitive industrial controls where ±0.1% system error budget permits looser reference tolerance. | Select ADR292ARZ-REEL7 if 12-bit system resolution suffices and BOM cost reduction is prioritized over long-term drift minimization. |
| REF192GS | 4.096 V output, ±3 mV initial accuracy, but higher 20 ppm/°C TC (max) and 25 μVp-p noise; also SOIC-8, pin-compatible. | Higher noise and drift limit use in >14-bit precision systems; suitable for general-purpose industrial I/O modules with moderate accuracy needs. | Choose REF192GS only if existing board layout mandates pin-compatible replacement and performance degradation to 14-bit ENOB is acceptable. |
Compared with ADR292GRZ-REEL7, the ADR292ARZ-REEL7 trades initial accuracy and temperature stability for lower unit cost, while REF192GS offers legacy compatibility at the expense of noise and drift - making ADR292GRZ-REEL7 the optimal choice for new designs demanding 16-bit+ resolution and field reliability.

FAQ
What is the minimum input voltage required for stable operation of the ADR292GRZ-REEL7?
The ADR292GRZ-REEL7 requires a minimum supply voltage of 4.4 V to maintain regulation across its full temperature and load range. At 5 mA output current and 125°C, the minimum VIN is ~4.9 V due to dropout - confirmed in Figure 15 of the Rev. F datasheet. Below 4.4 V, output voltage collapses nonlinearly and reference behavior is not guaranteed.
Does the ADR292GRZ-REEL7 require external capacitors, and if so, what values are recommended?
Yes - the ADR292GRZ-REEL7 requires a 0.1 μF ceramic capacitor from VOUT to GND for high-frequency noise suppression, plus a 10 μF tantalum or aluminum electrolytic capacitor for low-frequency stability and transient response, as shown in Figure 32 of the datasheet. Omitting either degrades PSRR and increases output impedance above 1 kHz.
Is the ADR292GRZ-REEL7 pin-compatible with the REF02 series?
Yes - the ADR292GRZ-REEL7 is explicitly designed as a pin-compatible upgrade to the REF02 family (e.g., REF02CPZ). Both use identical 8-lead SOIC pinout with VIN on Pin 2, GND on Pin 4, and VOUT on Pin 6. No PCB changes are needed for drop-in replacement, though XFET performance exceeds REF02 in noise, TC, and long-term drift.
What is the long-term stability specification for the ADR292GRZ-REEL7, and how is it measured?
The ADR292GRZ-REEL7 exhibits ≤50 ppm long-term stability after 1000 hours of operation at 125°C, measured as the maximum deviation of VOUT at 25°C before and after the stress test. This metric reflects die-level aging and is representative of 10+ years of field operation at lower temperatures - critical for unattended remote monitoring systems.
Can the ADR292GRZ-REEL7 drive a 10 kΩ load directly, and what is the resulting output error?
Yes - with a 10 kΩ load (ILOAD = 409.6 μA), the ADR292GRZ-REEL7 introduces ≤30 ppm/mA load regulation error, resulting in <13 μV shift (0.0003% of 4.096 V). This is well within the ±3 mV initial accuracy spec and does not require buffering for most precision ADC or DAC applications.
