Product details
Overview
5962-8982402PA from Analog Devices is a high-precision, buried Zener-based 5.000 V voltage reference IC with ±2.0 mV initial accuracy (M grade), 2 ppm/°C max temperature coefficient over 0°C to 70°C, and 100 nV/√Hz broadband noise. It features noise reduction (Pin 8), output trim (Pin 5), and ±10 mA sourcing/sinking capability - used as a primary reference for 12–16-bit DACs and ADCs in precision data acquisition systems.
For engineers reviewing the 5962-8982402PA datasheet, 5962-8982402PA pinout, 5962-8982402PA application, or 5962-8982402PA equivalent, this page delivers verified specifications, MIL-STD-883-compliant packaging details, real-world load regulation behavior, noise reduction implementation guidance, and validated alternative options for aerospace-grade analog signal chains.
Technical Context
The 5962-8982402PA implements a proprietary ion-implanted buried Zener diode combined with laser-trimmed thin-film resistors to achieve low drift and low noise - outperforming bandgap references in stability and spectral purity. Its internal buffer amplifier enables ±10 mA output drive while maintaining <100 µV/mA load regulation.
It supports three key configuration modes: standard 5 V positive reference (VIN→Pin 2, GND→Pin 4, VOUT→Pin 6), negative 5 V reference via ground-pin output, and stacked multi-voltage generation (5 V / 10 V / 15 V). The noise reduction pin (Pin 8) accepts a 1 µF capacitor to suppress high-frequency Zener noise by ~20% in 1 MHz bandwidth.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.000 V ±2.0 mV at 25°C - ensures ≤0.04% absolute error in calibration-critical 16-bit DAC reference paths. |
| Tempco | 2 ppm/°C max (0°C to 70°C) - guarantees ≤0.7 mV total drift across commercial temperature range, enabling stable performance without external compensation. |
| Output Noise | 4 µV p-p (0.1 Hz–10 Hz); 100 nV/√Hz @100 Hz - low enough to avoid degrading SNR in 16-bit ADCs with >90 dB dynamic range. |
| Load Regulation | 100 µV/mA (sourcing, 0–10 mA) - maintains reference integrity under dynamic converter current demands without droop-induced INL errors. |
| Quiescent Current | 2–3 mA - allows operation from 12 V or 15 V supplies with <30 mW power consumption, suitable for low-power precision instrumentation. |
| Short-Circuit Current | 45–60 mA - provides robust fault tolerance during board-level transient events without latch-up or permanent damage. |
| Long-Term Stability | 15 ppm/1000 hr - supports 10+ year system calibration intervals in avionics and test equipment applications. |
Pinout & Package
5962-8982402PA is supplied in an 8-lead CERDIP package (Q-8), compliant with MIL-STD-883, featuring hermetic ceramic construction and gold-plated leads for aerospace reliability. Pin 1, Pin 3, and Pin 7 are internal factory test points - no external connections permitted.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | TP1 | Factory trim pad - unconnected; dummy PCB pad only. |
| Pin 2 | VIN | Positive input supply (10.8–36 V); powers internal Zener and buffer amplifier. |
| Pin 3 | TP1 | Factory trim pad - unconnected; dummy PCB pad only. |
| Pin 4 | GND | Analog ground reference; must be low-impedance connection to minimize noise coupling. |
| Pin 5 | TRIM | External fine-adjust node; ±300 mV offset possible using 10 kΩ potentiometer for system-level calibration. |
| Pin 6 | VOUT | Regulated 5.000 V output; capable of sourcing or sinking up to ±10 mA with minimal regulation error. |
| Pin 7 | TP1 | Factory trim pad - unconnected; dummy PCB pad only. |
| Pin 8 | NOISE REDUCTION | Connects to internal Zener bias node; adding 1 µF to ground reduces 1 MHz noise from 200 µV p-p to ~160 µV p-p. |
Key Features
| Feature | Design Value |
|---|---|
| Laser-trimmed initial accuracy & tempco | Eliminates need for external trimming components and enables guaranteed ±2.45 mV total error (0°C–70°C) without calibration. |
| Buried Zener architecture | Delivers lower drift and lower 1/f noise than bandgap alternatives - critical for metrology-grade measurement front-ends. |
| Noise reduction pin (Pin 8) | Enables external RC filtering to suppress Zener-generated broadband noise without affecting DC accuracy or settling time. |
| Output trim capability (Pin 5) | Supports system-level fine-tuning to exactly 5.000 V or custom values (e.g., 5.12 V for binary-scaled DACs) with <0.01% gain impact. |
| MIL-STD-883 compliance | Validated for screening per Method 5005 - includes burn-in, thermal cycling, and hermeticity testing required for space and defense platforms. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| REF5050QPWRQ1 | 5.0 V, 3 ppm/°C max, 3.8 µV p-p noise, automotive AEC-Q100 qualified; requires external decoupling cap on REF pin. | Designed for automotive ECUs - lacks MIL-STD-883 screening and noise reduction pin. | Select when automotive qualification and extended temperature range (−40°C to +125°C) outweigh need for hermetic packaging and ultra-low noise. |
| ADR4550BRTZ-REEL7 | 5.0 V, 3 ppm/°C max, 1.2 µV p-p (0.1–10 Hz), SOIC-8; uses XFET topology - higher initial accuracy (±0.02%) but no trim or noise reduction pins. | Targeted at lab instrumentation - optimized for lowest noise, not military ruggedness or configurability. | Select when ultra-low 0.1–10 Hz noise dominates design priority and MIL-STD-883 compliance is not required. |
Compared with REF5050QPWRQ1 and ADR4550BRTZ-REEL7, the 5962-8982402PA uniquely combines MIL-STD-883 screening, on-chip noise reduction, external trim capability, and buried Zener stability - making it the only option qualified for flight-critical avionics reference designs where all three features are mandatory.

FAQ
What is the operating temperature range for the 5962-8982402PA?
The 5962-8982402PA is specified for operation from −55°C to +125°C with guaranteed performance across that full range. Its specified performance includes 20 ppm/°C max temperature coefficient and ±7.5 mV maximum total error over −55°C to +125°C, meeting MIL-STD-883 requirements for extended temperature operation in aerospace and defense systems.
Does the 5962-8982402PA require external capacitors for stability?
The 5962-8982402PA does not require external capacitors for basic stability - it operates reliably with only VIN and GND connections. However, a 1 µF capacitor between Pin 8 (NOISE REDUCTION) and GND is recommended to reduce broadband noise by ~20%, and a 0.1 µF capacitor on VIN is advised for high-noise supply environments to improve PSRR.
Can the 5962-8982402PA be used as a negative voltage reference?
Yes, the 5962-8982402PA can generate a precision −5.000 V output by connecting VIN to a +6 V to +30 V supply, grounding VOUT (Pin 6), and referencing the output from GND (Pin 4) through a current-setting resistor to a −15 V rail. This configuration maintains the same temperature coefficient and long-term stability as the standard +5 V mode.
What is the purpose of Pins 1, 3, and 7 on the 5962-8982402PA?
Pins 1, 3, and 7 are internal factory test points (TP1) used during wafer probing and final test. They are not functional terminals and must remain unconnected in end-user circuitry. Only dummy PCB pads should be placed at these locations - any soldered connection may compromise device reliability or parametric performance.
How does the 5962-8982402PA compare to commercial-grade AD586 variants like AD586M?
The 5962-8982402PA is the MIL-STD-883-qualified version of the AD586M, sharing identical electrical specifications (±2.0 mV accuracy, 2 ppm/°C tempco, 100 nV/√Hz noise) but undergoing additional screening including burn-in, thermal cycling, and hermeticity testing. It is packaged in an 8-lead CERDIP (Q-8) rather than PDIP or SOIC, ensuring reliability in high-vibration, high-humidity, and radiation-prone environments.
