Product details
Overview
5962-8982401PA from Analog Devices is a high-precision, laser-trimmed 5.000 V buried Zener 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 spectral noise density. It sources or sinks up to 10 mA and features dedicated noise reduction (Pin 8) and output trim (Pin 5) terminals. It is used as a stable reference for 12–16-bit DACs and ADCs in precision data acquisition systems.
For engineers reviewing the 5962-8982401PA datasheet, 5962-8982401PA pinout, 5962-8982401PA application, or 5962-8982401PA equivalent, this MIL-PRF-38535 certified Class B device delivers military-grade stability, low-drift performance across −55°C to +125°C, and compatibility with legacy 5 V reference designs requiring upgrade paths without PCB redesign.
Technical Context
The 5962-8982401PA employs a proprietary ion-implanted buried Zener diode architecture with laser-trimmed thin-film resistors, enabling superior long-term stability (15 ppm/1000 hr) and lower drift than bandgap references. Its internal buffer amplifier supports bidirectional 10 mA load current while maintaining <100 µV/mA sourcing load regulation.
It integrates a dedicated noise reduction terminal (Pin 8) that forms a low-pass filter with an external 1 µF capacitor, reducing broadband noise from ~200 µV p-p (1 MHz) to ~160 µV p-p. The TRIM pin (Pin 5) enables ±6% gain adjustment for system-level calibration to exact 5.000 V or binary-scaled voltages like 5.12 V.

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| REF5050QPWR | Bandgap-based, 5 ppm/°C max, 3.5 µV p-p (0.1–10 Hz), SOIC-8 package only | Lower cost, non-hermetic; unsuitable for extended temperature or radiation environments | Select for commercial industrial systems where MIL-spec is not required and board space is constrained |
| LM399H | Heated buried Zener, 0.3 ppm/°C typical, 1.5 µV p-p (0.1–10 Hz), TO-99 metal can | Higher power (600 mW), slower warm-up (>5 min), no noise reduction pin | Select when ultra-low drift dominates over power, size, and turn-on time constraints |

FAQ
What is the operating temperature range for the 5962-8982401PA?
The 5962-8982401PA is specified for operation from −55°C to +125°C with guaranteed performance across this full range. Its maximum output voltage drift is 10 ppm/°C over −55°C to +125°C, and it undergoes full MIL-STD-883 screening including temperature cycling and 100°C production testing for CERDIP-packaged units. This makes the 5962-8982401PA suitable for extreme-environment deployment in missile guidance, satellite payloads, and downhole drilling electronics.
Does the 5962-8982401PA require external components to function?
No, the 5962-8982401PA operates as a complete 5 V reference with only VIN (Pin 2) and GND (Pin 4) connections required. External components are optional: a 1 µF capacitor on Pin 8 improves noise performance, and a resistor network on Pin 5 enables fine-trim calibration. The 5962-8982401PA draws only 2–3 mA quiescent current and regulates accurately from 10.8 V to 36 V input, eliminating need for pre-regulators in most 12–15 V systems.
How does the noise reduction feature of the 5962-8982401PA work?
The 5962-8982401PA's NOISE REDUCTION pin (Pin 8) connects internally to the buried Zener's bias node. Adding a 1 µF capacitor from Pin 8 to ground forms a low-pass RC filter with the Zener's internal resistance (~4 kΩ), setting a 3 dB point at ~12 Hz. This reduces broadband (1 MHz) noise from ~200 µV p-p to ~160 µV p-p without affecting DC accuracy or load regulation-enabling cleaner reference signals for high-SNR ADCs without external op-amps or complex filtering.
Can the 5962-8982401PA be used as a negative reference?
Yes, the 5962-8982401PA can generate a precision −5.000 V output by reversing connections: tie VIN (Pin 2) to +6 V to +30 V, ground VOUT (Pin 6), and connect GND (Pin 4) through a current-setting resistor to a −15 V rail. The −5 V appears at Pin 4, with identical temperature coefficient (10 ppm/°C) and long-term stability (15 ppm/1000 hr) as the positive configuration. This dual-polarity capability is documented in Figure 19 of the AD586 Rev. G datasheet and applies identically to the 5962-8982401PA.
Is the 5962-8982401PA pin-compatible with other AD586 variants?
Yes, the 5962-8982401PA shares the identical 8-lead CERDIP (Q-8) pinout and electrical behavior with all AD586 family members, including AD586JQ, AD586LQ, and AD586TQ. Pins 1, 3, and 7 are unconnected test points; VIN (2), GND (4), TRIM (5), VOUT (6), and NOISE REDUCTION (8) retain identical functions and specifications. This allows direct substitution in existing AD586Q designs without layout modification, provided the higher-grade M-spec accuracy and MIL-qualification meet system requirements.
