Overview

5962R0051601VPA from Analog Devices is a radiation-hardened, monolithic silicon precision voltage reference delivering +5 V output with ±0.015 V initial accuracy over –55°C to +125°C, 8.5 ppm/°C temperature coefficient, 15 µV_P-P (0.1–10 Hz) noise, and 100 ppm/1 kHr long-term stability - used in satellite power regulation, missile guidance analog signal chains, and nuclear instrumentation front-ends.

For engineers reviewing the 5962R0051601VPA datasheet, 5962R0051601VPA pinout, 5962R0051601VPA application, or 5962R0051601VPA equivalent, key selection criteria include radiation tolerance (50 krads(Si) at low dose rate), adjustable output via external trim resistor, hermetic flat-pack packaging, and compliance with MIL-PRF-38535 Class V requirements.

Technical Context

This device implements a bandgap-based reference core with internal trimming capability and on-chip temperature sensing. It supports output adjustment via an external 10 kΩ potentiometer between TRIM and GND, enabling fine-tuning of VOUT across ±3% range while maintaining specified TCVO and load regulation.

Designed for extreme environments, it features indefinite short-circuit protection, operates from 8 V to 33 V input, delivers up to 10 mA load current, and sustains junction temperatures from –65°C to +150°C. Its radiation hardness assurance is validated per MIL-STD-883 method 1019, condition D (low-dose-rate testing).

FAQ

What is the radiation hardness specification for 5962R0051601VPA?

The 5962R0051601VPA is rated for 50 krads(Si) total ionizing dose (TID) under low-dose-rate conditions (≤10 mrads(Si)/s), tested per MIL-STD-883 method 1019, condition D. This qualifies it for use in low-earth orbit satellites and tactical defense electronics where cumulative radiation exposure must be managed without functional degradation. Post-irradiation electrical parameters remain within datasheet limits at TA = +25°C ±5°C.

Does 5962R0051601VPA require an external capacitor for stability?

No, the 5962R0051601VPA is internally compensated and does not require an external output capacitor for stability. It maintains phase margin and transient response across its full operating range (–55°C to +125°C, 0–10 mA load) without added capacitance. However, a 0.1 µF ceramic bypass capacitor at VIN is recommended to suppress high-frequency supply noise that could modulate the reference output.

Can the output voltage of 5962R0051601VPA be adjusted, and how is it done?

Yes, the output voltage of 5962R0051601VPA is adjustable over ±3% using an external 10 kΩ potentiometer connected between the TRIM pin and GND. The wiper of the potentiometer connects to TRIM, allowing fine-tuning of VOUT while preserving all specified performance parameters including temperature coefficient and noise. Adjustment is performed at room temperature before final system calibration.

What is the maximum load current supported by 5962R0051601VPA?

The 5962R0051601VPA supports a maximum continuous load current of 10 mA at TA = –55°C to +125°C, as verified by load regulation testing (0.015 %/mA). It also provides indefinite short-circuit protection, allowing safe operation even if VOUT is inadvertently grounded. For loads exceeding 10 mA, an external buffer amplifier driven by 5962R0051601VPA is required to maintain output accuracy.

Is 5962R0051601VPA compliant with MIL-PRF-38535, and which device class does it meet?

Yes, 5962R0051601VPA complies with MIL-PRF-38535 and is qualified as a Class V device - the highest assurance level for space applications. It meets all requirements for radiation hardness assurance, screening, qualification, and conformance inspection defined in the specification, including group A–E testing and burn-in per method 1015 of MIL-STD-883. Its RHA designator "R" confirms radiation-hardened status per drawing 5962-00516 revision D.
