Product details
Overview
5962-8982503PA from Analog Devices is a high-precision, laser-trimmed 10 V monolithic voltage reference using a buried Zener diode architecture. It delivers ±5 mV initial accuracy, ≤5 ppm/°C temperature coefficient (−55°C to +125°C), and 4 μV p-p (0.1 Hz–10 Hz) output noise. Designed for military-grade instrumentation and precision data conversion systems, it serves as the primary reference for 14-bit and 16-bit ADCs/DACs requiring long-term stability and low thermal drift.
For engineers reviewing the 5962-8982503PA datasheet, 5962-8982503PA pinout, 5962-8982503PA application, or 5962-8982503PA equivalent, this MIL-STD-883-compliant device offers verified performance in extended temperature operation, noise-reduction capacitor support, fine-trim capability, and compatibility with legacy 10 V reference footprints - critical for avionics, test equipment, and radiation-tolerant embedded systems.
Technical Context
The 5962-8982503PA implements a proprietary ion-implanted buried Zener diode combined with laser-trimmed thin-film resistors to achieve low-drift, low-noise voltage regulation without external compensation. Its internal buffer amplifier provides load regulation of ±100 μV/mA and supports sourcing/sinking up to ±10 mA while maintaining <5 ppm/°C drift over −55°C to +125°C.
It features dedicated terminals for noise reduction (Pin 8) and fine output trimming (Pin 5), enabling system-level calibration and broadband noise filtering via external capacitors. The device operates from 13.5 V to 36 V input and maintains 15 ppm/1000 hr long-term stability - essential for mission-critical calibration chains and metrology-grade signal conditioning.

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD587UQ | Same die, identical specifications, non-military grade marking; not screened to MIL-STD-883. | Lacks burn-in, hermeticity verification, and extended temperature screening - unsuitable for flight hardware. | Select only for ground-test prototypes or commercial-grade subsystems where cost outweighs qualification rigor. |
| REF5010QPWRQ1 | Bandgap-based, 10 ppm/°C max drift, 3.8 μV p-p noise, automotive AEC-Q100 qualified. | Higher drift and different noise profile; lacks fine-trim and noise-reduction pin - limits use in metrology-grade systems. | Consider only for automotive ECUs needing 10 V reference with AEC-Q100 compliance but no military temp range or MIL-STD-883. |

FAQ
What is the maximum total error of the 5962-8982503PA over its full operating temperature range?
The 5962-8982503PA guarantees a maximum total error of ±14 mV between −55°C and +125°C. This includes initial accuracy (±5 mV), temperature-induced drift (≤5 ppm/°C), and long-term stability contribution. The specification is validated per MIL-STD-883 test methods and applies to all units in the Q-8 CERDIP package.
Does the 5962-8982503PA support noise reduction, and how is it implemented?
Yes, the 5962-8982503PA includes a dedicated NOISE REDUCTION pin (Pin 8) that allows connection of an external capacitor to ground. A 1 μF capacitor reduces broadband (1 MHz) noise from ~200 μV p-p to ~160 μV p-p by forming a low-pass filter with internal Zener resistance. This feature is documented in Figure 6 and Section "Noise Performance and Reduction" of the AD587 Rev. H datasheet.
Can the 5962-8982503PA be used to generate a negative reference voltage?
Yes, the 5962-8982503PA can be configured as a −10.000 V reference by grounding the VOUT pin (Pin 6), connecting the GND pin (Pin 4) to a −15 V rail through a current-limiting resistor (RS < 1 kΩ), and powering +VIN (Pin 2) from ≥+3.5 V. This configuration maintains the same temperature coefficient and long-term stability as the standard positive mode, as confirmed in Figure 17 and the "Negative Reference Voltage" section of the datasheet.
What package type and lead finish does the 5962-8982503PA use?
The 5962-8982503PA is supplied exclusively in an 8-lead Ceramic Dual In-Line Package (CERDIP, Q-8) with gold-plated leads. This hermetic package meets MIL-STD-883 requirements for moisture resistance, thermal cycling, and mechanical robustness - critical for aerospace and defense deployments.
Is fine trimming supported on the 5962-8982503PA, and what is its adjustment range?
Yes, the 5962-8982503PA provides a TRIM pin (Pin 5) enabling ±3% output voltage adjustment - sufficient to calibrate to exactly 10.000 V against a metrology standard or set binary-scaled values like 10.24 V. The fine-trim circuitry preserves temperature coefficient and noise performance, as detailed in Figure 4 and the "Applying the AD587" section of the datasheet.
