Analog Devices Inc. 5962R0051601VGA

Overview

5962R0051601VGA from Analog Devices is a monolithic silicon +5 V precision voltage reference with adjustable output, qualified to MIL-PRF-38535 Class V for space applications, featuring 8.5 ppm/°C temperature coefficient, ±3.0% output adjustment range, and 100 ppm/1 kHr long-term stability. It operates across –55°C to +125°C and delivers 5.000 V ±15 mV output at zero load.

For engineers reviewing the 5962R0051601VGA datasheet, 5962R0051601VGA pinout, 5962R0051601VGA application, or 5962R0051601VGA equivalent, key selection criteria include radiation hardness assurance (100 krads(Si) total dose), hermetic metal-can package (case outline G), and compliance with MIL-STD-883 method 1019 condition A for space-grade TID testing.

Technical Context

This device implements a bandgap-based reference core with external trim capability via a 10 kΩ potentiometer, enabling precise calibration of output voltage over temperature and life. Its terminal configuration includes dedicated TEMP, TRIM, VIN, VOUT, and GND pins - with case ground tied to Pin 2 in case outline G - supporting high-reliability biasing and thermal monitoring in radiation-hardened systems.

Designed for mission-critical analog signal chains, the 5962R0051601VGA maintains stable operation under extreme environmental stress: indefinite short-circuit tolerance, 40 V absolute maximum input, and junction temperature range of –65°C to +150°C. Its electrical performance is guaranteed post-irradiation only under MIL-STD-883, method 1019, condition A, with pre- and post-test values identical unless otherwise specified.

FAQ

What is the radiation hardness assurance level of the 5962R0051601VGA?

The 5962R0051601VGA is radiation-hardened to 100 krads(Si) total ionizing dose (TID) per MIL-STD-883 method 1019, condition A. This qualification applies to device type 01 and is verified for space environments including geosynchronous orbit. The 'R' in the PIN indicates RHA marking, and the 'V' denotes device class V - full MIL-PRF-38535 qualification with DLA oversight. Post-irradiation electrical parameters match pre-test values within specified limits for VOUT, TCVO, and noise.

Which package type does the 5962R0051601VGA use, and how is the case grounded?

The 5962R0051601VGA uses case outline G (MACY1-X8), an 8-terminal hermetic metal can package. Per Figure 1 and Sheet 8 of the drawing, Pin 2 is VIN, Pin 4 is GND, and the metal case itself is electrically connected to Pin 4. This configuration requires direct soldering or mechanical bonding of the can to the PCB ground plane to maintain shielding integrity and thermal dissipation. Pins 1, 7, and 8 are NC and must remain unconnected.

Can the 5962R0051601VGA be adjusted to output voltages other than +5 V?

Yes, the 5962R0051601VGA supports ±3.0% output adjustment using an external 10 kΩ potentiometer connected between TRIM (Pin 5), VOUT (Pin 6), and GND (Pin 4). This allows fine-tuning of the nominal +5.000 V output to values between 4.85 V and 5.15 V while maintaining all specified performance parameters including tempco and noise. Adjustment is performed at room temperature before system burn-in and does not require recalibration over temperature.

What is the maximum load current the 5962R0051601VGA can drive while maintaining specification?

The 5962R0051601VGA guarantees full specification compliance up to 10 mA load current, as confirmed in Table I under "Load current" for subgroup 1. Load regulation remains ≤0.01 %/mA from 0 to 10 mA, ensuring minimal output deviation under varying current demand. Beyond 10 mA, performance degrades - notably increased self-heating affects tempco and long-term stability - and operation above 60 mA sink current (short-circuit limit) risks permanent damage despite indefinite short-circuit survival at lower currents.

How does the TEMP pin (Pin 3) function in the 5962R0051601VGA?

Pin 3 (TEMP) provides an analog voltage proportional to the internal die temperature, enabling real-time thermal monitoring and derating in closed-loop systems. Its output scales linearly with junction temperature and is used to trigger thermal shutdown, adjust gain in temperature-sensitive signal chains, or validate thermal models during qualification testing. Unlike standard temperature sensors, TEMP is not calibrated for absolute accuracy but provides repeatable relative tracking - critical for detecting abnormal heating due to radiation-induced leakage or bond wire degradation in long-duration missions.
