ADI 5962 9689202VJA(AD565ATD)

Two hundred and fifty nanoseconds to ±½ LSB — that settling specification defines the AD565A’s market position in military DAC design. For radar, electronic warfare, and high-speed waveform generation applications where the DAC must settle within a fraction of a microsecond to maintain timing margins, the 5962-9689202VJA delivers a qualified solution that does not require trading precision for speed. The T grade under SMD 5962-96892 guarantees ±¼ LSB linearity overtemperature — the same tightness required for precision applications — in a device that also switches at 35 ns full-scale transitions. The on-chip buried Zener reference, laser-trimmed to 10 ppm/°C typical gain TC, rounds out a genuinely complete high-speed DAC solution in a single military-qualified component.

5962-9689202VJA Architecture: Bipolar Current-Steering for Sub-Microsecond Settling

The AD565A’s speed comes from its bipolar current-steering architecture — unlike CMOS R-2R ladders that switch voltage through finite impedances, the bipolar switches steer pre-established currents between output nodes with transition times governed by transistor switching rather than RC charging. Twelve precision switches, each controlling a binary-weighted current fraction from the buried Zener reference, produce the output current word with the predictability that laser-trimmed thin-film resistor ratios provide. The control amplifier that drives the switches is designed specifically for minimum glitch energy during code transitions — a specification that matters in radar and EW applications where DAC glitch area directly contributes to spurious spectral content. The output current can be converted to voltage in unipolar or bipolar configurations using the on-chip span resistors and an external op amp, with the buried Zener supplying both the reference current and the bipolar offset current in bipolar mode.

5962-9689202VJA vs Other Military 12-Bit and 16-Bit DAC Options

Speed grade selection often drives the choice between the AD565A and slower, higher-resolution alternatives in military signal chain design:

The 5962-9689202VJA is the correct choice when settling speed is the primary specification — radar update rates, EW waveform generation, and high-speed ATE stimulus applications where the DAC must settle within hundreds of nanoseconds. For precision closed-loop control or ATE where accuracy and voltage range flexibility outweigh settling speed, the AD7846 or AD660 alternatives address those requirements.

Frequently Asked Questions (FAQ)

What Is the ADI 5962-9689202VJA and What Is Its Commercial Equivalent?

The 5962-9689202VJA is the military SMD procurement designation for Analog Devices’ AD565ATD, processed to MIL-STD-883B under drawing 5962-96892. It is a high-speed 12-bit bipolar current-steering DAC with 250 ns maximum settling to ±½ LSB, ±¼ LSB T-grade linearity guaranteed overtemperature, on-chip buried Zener reference, and flexible unipolar/bipolar output configurations, in a 24-lead ceramic DIP package rated for military operation from –55°C to +125°C.

What Makes the AD565A Faster Than Other Precision Military DACs?

The bipolar current-steering architecture switches pre-established currents between output nodes using transistor switching speeds, rather than charging output impedances through resistive networks as CMOS alternatives do. Full-scale transitions complete in under 35 ns, and the entire output settles to ±½ LSB within 250 ns maximum — approximately 40× faster than precision 16-bit voltage output DACs like the AD7846 or AD660, which settle in the 10 µs range.

How Does the AD565A’s On-Chip Reference Compare to Using an External Reference?

The AD565A’s buried Zener reference is laser-trimmed at the wafer level for both absolute value and temperature coefficient, achieving a typical full-scale gain TC of 10 ppm/°C. For applications requiring tighter TC, the companion AD566A accepts an external precision reference — the 5962-8866302LA AD584S pin-programmable reference or the 5962-9078501MLA AD780S are natural qualified companions for such applications.

What Output Configurations Does the 5962-9689202VJA Support?

The AD565A supports unipolar 0V to +10V output using the internal reference and on-chip span resistors with an external output op amp. Bipolar ±5V output is configured by connecting the bipolar offset pin; ±10V bipolar output requires an external reference scaling resistor. All configurations use the internal buried Zener reference for both the DAC reference current and the bipolar offset current.
