Product details
Overview
ADR292FRZ-REEL 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 across −40°C to +125°C - ideal for high-resolution ADC/DAC references in battery-powered instrumentation.
For engineers reviewing the ADR292FRZ-REEL datasheet, ADR292FRZ-REEL pinout, ADR292FRZ-REEL application, or ADR292FRZ-REEL equivalent, key selection criteria include its XFET® architecture enabling ultralow thermal hysteresis (50 ppm), tight load regulation (30 ppm/mA), and compatibility with 3 V/5 V data converter systems requiring long-term stability and minimal self-heating.
Technical Context
The ADR292FRZ-REEL uses Analog Devices' XFET® reference topology - an extra-implanted junction FET circuit generating a ~0.5 V intrinsic reference with negative TC, compensated by a PTAT current source to achieve precise 4.096 V output. This architecture delivers one-quarter the noise of comparable band gap references at same supply current.
It functions as a two-terminal series voltage reference: VIN supplies regulated current to the internal XFET core, GND establishes the reference ground reference, and VOUT delivers the stabilized 4.096 V output. The device exhibits 30 ppm/V line regulation and 30 ppm/mA load regulation under nominal conditions, with thermal hysteresis limited to 50 ppm over −40°C ↔ +125°C cycling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 4.096 V ±3 mV (E grade) - enables exact 12-bit full-scale alignment with 4096-count ADCs without scaling. |
| Initial Accuracy | ±0.07% - eliminates need for system-level trimming in portable 5 V measurement front-ends. |
| Temp. Coefficient | 8 ppm/°C max (E grade) - contributes ≤±0.8 mV drift over −40°C to +85°C, critical for uncalibrated field instruments. |
| Noise (0.1–10 Hz) | 12 μVp-p - preserves ENOB in 16-bit sigma-delta converters like AD7701 without external filtering. |
| Quiescent Current | 15 μA max - supports >1-year battery life in solar-powered loop-powered transmitters drawing <100 μA total. |
| Supply Range | 4.4 V to 15 V - allows direct use with 5 V rails and tolerance for automotive or industrial supply ripple. |
| Output Current | 5 mA - drives ADC reference inputs, op-amp bias networks, and small DAC loads without external buffers. |
Pinout & Package
ADR292FRZ-REEL is supplied in an 8-lead SOIC (R-8) package per JEDEC MS-012-AA, with 1.27 mm lead pitch and standard narrow-body footprint. Pin 1 is marked via notch or bevel; pins 1, 3, 5, 7, and 8 are internally connected but designated NC (no connect) and must remain unconnected in PCB layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 2 (VIN) | Input Supply Terminal | Accepts 4.4 V–15 V input; minimum headroom is 0.1 V at 5 mA load - enables ultra-low-dropout operation in 5 V systems. |
| Pin 4 (GND) | Reference Ground | Must be connected to clean analog ground plane; Kelvin sensing recommended when routing high-current loads. |
| Pin 6 (VOUT) | Precision Output Terminal | Delivers regulated 4.096 V; requires 0.1 µF ceramic bypass capacitor directly to GND for optimal noise performance. |
Key Features
| Feature | Design Value |
|---|---|
| XFET® Reference Architecture | Enables 12 μVp-p low-frequency noise and 50 ppm thermal hysteresis - outperforms band gap references in metrology-grade stability. |
| Extended Temperature Range | Specified from −40°C to +125°C - supports deployment in automotive engine control units and industrial process sensors without derating. |
| Pin Compatibility | Direct replacement for REF02 and REF19x series - allows drop-in upgrade of legacy 4.096 V reference designs with no PCB change. |
| Low Power Operation | 12 μA typical supply current at 25°C - reduces self-heating error to <0.5 ppm, preserving accuracy in sealed enclosures. |
| High Output Drive | 5 mA sourcing capability - eliminates need for external buffer op-amps when driving multiple SAR ADC references or precision DACs. |

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-REEL | E grade (±3 mV), same 4.096 V output and SOIC-8 package, but rated for −40°C to +125°C with identical XFET® core. | Same functional role; differs only in tape-and-reel packaging (FRZ = Pb-free, RoHS-compliant reel; ARZ = standard reel). | Select ADR292FRZ-REEL for RoHS-compliant production; ADR292ARZ-REEL where legacy Pb-based assembly is permitted. |
| REF192GS | 4.096 V output, ±4 mV initial accuracy, 15 ppm/°C TC, higher 35 μA supply current, same SOIC-8 pinout. | Higher power consumption and drift limit use in ultra-low-power or wide-temperature deployments. | Choose REF192GS only if ADR292FRZ-REEL is unavailable; expect 2.3× higher quiescent current and reduced long-term stability. |
Compared with ADR292FRZ-REEL, ADR292ARZ-REEL offers identical electrical performance with non-RoHS packaging, while REF192GS trades lower cost for higher drift and current - making ADR292FRZ-REEL optimal for battery-critical, high-accuracy applications demanding regulatory compliance.

FAQ
What is the maximum supply voltage for ADR292FRZ-REEL?
The absolute maximum supply voltage for ADR292FRZ-REEL is 18 V, but continuous operation above 15 V is not recommended due to thermal dissipation limits. The device is specified for reliable operation from 4.4 V to 15 V, with 15 V being the upper bound of its guaranteed electrical performance across temperature.
Does ADR292FRZ-REEL require an output capacitor?
Yes, ADR292FRZ-REEL requires a 0.1 µF ceramic capacitor between VOUT and GND, placed as close as possible to the device pins. This capacitor stabilizes the output impedance and suppresses high-frequency noise; omitting it degrades PSRR and increases broadband noise beyond the specified 640 nV/√Hz density.
Is ADR292FRZ-REEL pin-compatible with REF02?
Yes, ADR292FRZ-REEL is explicitly pin-compatible with REF02 and REF19x series devices in SOIC-8 packages. Pin 2 is VIN, Pin 4 is GND, and Pin 6 is VOUT - enabling direct replacement without PCB modification, though layout best practices (e.g., ground plane integrity) must still be observed.
What grade does ADR292FRZ-REEL correspond to?
ADR292FRZ-REEL is the E grade variant of the ADR292 family, offering ±3 mV (±0.07%) initial output accuracy and 8 ppm/°C maximum temperature coefficient over −40°C to +125°C - confirmed by Analog Devices' ordering guide and Rev. F datasheet Table 5.
Can ADR292FRZ-REEL drive a 5 kΩ load?
Yes, ADR292FRZ-REEL can drive a 5 kΩ load (ILOAD = 0.82 mA) with negligible error: its 30 ppm/mA load regulation contributes only ±25 ppm (±0.1 mV) deviation, well within the ±3 mV initial accuracy budget. No external buffer is required for such loads.
