The ADI 5962-9201601MEA is the military SMD procurement designation for Analog Devices' AD766SD processed to MIL-STD-883B, in a 16-lead ceramic side-brazed DIP package rated for the full military temperature range. The AD766 DACPORT concept solves a specific integration problem in DSP-based military signal chains: rather than requiring a parallel-input DAC, an external serial-to-parallel converter, a separate voltage reference, and a discrete output amplifier, it integrates all four functions onto a single BiMOS II die with a three-wire serial interface that connects directly to the serial ports of the most widely deployed military DSP processors — including the ADSP-2101, TMS320CXX, and DSP56001 — without any glue logic.
The result is a genuinely complete analog output channel in a single qualified component. The 16-bit current-steering DAC core is laser-trimmed to achieve the production-tested 94 dB SNR and –81 dB THD specifications that make the AD766 usable in demanding signal generation applications — radar jamming, noise cancellation, precision waveform generation — where DAC dynamic performance directly determines system capability. The ±3V output amplifier is short-circuit protected, settles fast, and drives loads directly without an external buffer. For military procurement teams, the 5962-9201601MEA part number provides the standardized DoD acquisition path with full MIL-STD-883B qualification documentation.

In DSP-based military systems, the analog output stage is often where integration complexity accumulates — a serial DAC, a deserializer, an external reference, an output buffer, each a separate component on the qualified parts list. The ADI 5962-9201601MEA eliminates that complexity. As the military designation for the AD766SD DACPORT, it integrates the entire analog output channel — serial interface, DAC core, voltage reference, and output amplifier — into a single 16-lead ceramic DIP, processed to MIL-STD-883B under SMD 5962-92016. One qualified component replaces four, and the three-wire serial interface connects directly to the DSP processor without additional logic.
5962-9201601MEA Performance: 94 dB SNR in a Complete DAC Solution
The AD766’s dynamic performance specifications — 94 dB minimum SNR and –81 dB maximum THD — are production tested, not just characterized. This matters in military signal generation applications where the DAC’s spurious performance sets the floor for the entire system’s dynamic range. Laser-trimming of the silicon chromium thin-film resistors reduces differential nonlinearity at midscale, and an optional linearity trim pin allows further THD reduction for small-signal applications. The output amplifier delivers ±3V with high slew rate, fast settling, and short-circuit protection — operational requirements in military systems where output loads are not always controlled and fault conditions must be survived without device damage.
5962-9201601MEA vs Other Military DAC Options
For military procurement teams evaluating DAC options, the AD766 occupies a specific niche defined by its serial DSP interface and complete integration:
| 5962-9201601MEA (AD766S) | 5962-8770002EA (AD7226) | 5962-8778902EA (AD7524) | |
|---|---|---|---|
| Resolution | 16-bit | 8-bit (×4 ch) | 8-bit |
| Interface | Serial (3-wire DSP) | Parallel 8-bit bus | Parallel 8-bit bus |
| Channels | 1 | 4 | 1 |
| On-chip Reference | Yes (bandgap) | No | No |
| On-chip Output Amp | Yes | Yes (laser-trimmed) | No (current output) |
| SNR | 94 dB min | N/A | N/A |
| Best For | DSP serial output, high dynamic range | Multi-channel voltage output | Multiplying DAC, AGC |
The 5962-9201601MEA is the right choice when the system is DSP-driven, resolution and dynamic performance matter, and board space or component count reduction is a design priority. For multi-channel parallel-bus architectures or multiplying DAC applications, the AD7226 and AD7524 military variants address those requirements.

Frequently Asked Questions (FAQ)
What Is the ADI 5962-9201601MEA and What Is Its Commercial Equivalent?
The 5962-9201601MEA is the military SMD procurement designation for Analog Devices’ AD766SD, processed to MIL-STD-883B under drawing 5962-92016. It is a complete 16-bit DSP DACPORT integrating a serial three-wire DSP interface, 16-bit current-steering DAC, internal bandgap voltage reference, and voltage output op amp, with 94 dB minimum SNR and –81 dB maximum THD, in a 16-lead ceramic side-brazed DIP rated for military operation from –55°C to +125°C.
What DSP Processors Are Directly Compatible With the 5962-9201601MEA?
The AD766 serial interface is directly compatible with the ADSP-2101, TMS320CXX, and DSP56001 serial port protocols. Two’s-complement data is clocked MSB first on falling clock edges at up to 12.5 MHz, consistent with the serial port conventions of these processors. No deserializer, level translator, or timing logic is required between the processor serial port and the AD766.
What Does “Production Tested” Mean for the SNR and THD Specifications?
Production testing means every shipped device has been individually tested against the 94 dB SNR and –81 dB THD limits — not just a sample from the lot. This gives procurement teams and system designers higher confidence in the specified dynamic performance than characterization-only data provides, which matters in military signal generation applications where unit-to-unit variation in spurious performance can affect system-level compliance.
How Does the 5962-9201601MEA Compare to Parallel-Input Military DACs?
The AD766 trades parallel bus bandwidth for integration and dynamic performance. Parallel DACs like the 5962-8770002EA AD7226 offer multiple channels and direct processor bus interface but at 8-bit resolution without on-chip output amplifiers or references. The AD766 is the appropriate choice when a single high-resolution, high-dynamic-range analog output channel is needed from a DSP serial port, with minimum component count.
