The ADI 5962-9312901MPA is the military SMD designation for Analog Devices' AD829SQ processed to MIL-STD-883B, in an 8-lead hermetic CERDIP package rated for the full –55°C to +125°C military temperature range. The AD829 is not a general-purpose op amp dressed up for video — it was designed specifically for professional video signal processing, with 0.04° differential phase and 0.02% differential gain at 3.58 MHz and 4.43 MHz into reverse-terminated 50Ω or 75Ω cables meeting the performance requirements of broadcast-quality signal distribution. At 1.7 nV/√Hz input voltage noise, it also serves precision low-noise amplification applications where the noise floor of the amplifier stage determines the system's measurement capability.
The user-adjustable external compensation network is the feature that most distinguishes the AD829 from fixed-compensation high-speed op amps. Two external compensation pins allow the closed-loop bandwidth to be set from unity gain through gain-of-20 operation: at unity gain, external capacitors reduce bandwidth for stability; at higher gains, compensation can be lightened to maintain >50 MHz closed-loop bandwidth. This flexibility means the AD829 can be optimized for the specific gain and bandwidth requirements of each stage in the signal chain, rather than being over-compensated for worst-case unity gain stability at the expense of bandwidth in higher-gain configurations. Processed to MIL-STD-883B under SMD 5962-93129, the 5962-9312901MPA brings these capabilities into the DoD qualified parts framework for military video, radar, and communications program procurement.

The AD829 occupies a specific position in the military op amp landscape that generic high-speed amplifiers do not fill: a device with 1.7 nV/√Hz noise, 230 V/µs slew rate, and differential phase/gain specifications that make it directly usable in professional video signal chains — all in a single 8-lead hermetic CERDIP package processed to MIL-STD-883B. For military programs combining video or imaging systems with precision analog signal conditioning, the 5962-9312901MPA covers both requirements from a single qualified component rather than requiring separate video and precision op amps for different stages.
5962-9312901MPA Architecture: Adjustable Compensation for Gain-Optimized Bandwidth
The external compensation architecture of the AD829 is what enables it to maintain >50 MHz bandwidth across a 1-to-20 gain range. Fixed-compensation amplifiers trade bandwidth for stability at lower gains — a unity-gain-stable amplifier at 750 MHz GBW is closed-loop stable at gain-of-1 but loses bandwidth progressively as gain increases. The AD829 allows the compensation to be adjusted for the actual operating gain, so a gain-of-10 configuration can use lighter compensation than a gain-of-1 stage and recover the bandwidth that fixed compensation would sacrifice. Two capacitor pads on the PCB implement this — values are tabulated in the datasheet for each gain setting, making the selection a straightforward component choice. In military video applications driving reverse-terminated 75Ω cables, the AD829’s 0.04° differential phase and 0.02% differential gain meet the performance requirements that determine picture quality in signal distribution systems.
5962-9312901MPA vs Other Military High-Speed Op Amps
The AD829 addresses a different performance tier than the precision low-noise op amps in the military catalog. Compared to the precision amplifiers in the existing ADI military portfolio:
| 5962-9312901MPA (AD829S) | 5962-8876401LA (OP27E) | 5962-8872101PA (OP270Z) | |
|---|---|---|---|
| Input Noise | 1.7 nV/√Hz | 3 nV/√Hz | 5 nV/√Hz |
| Slew Rate | 230 V/µs | 2.8 V/µs | 2.4 V/µs |
| GBW | 750 MHz | 8 MHz | 5 MHz |
| Compensation | User-adjustable | Fixed (unity-gain stable) | Fixed (unity-gain stable) |
| Best For | Video, wideband, high-speed | Precision DC, low drift | Dual precision, low drift |
The AD829 is the correct choice when bandwidth and slew rate are the primary requirements — video signal processing, wideband IF amplification, fast pulse amplification. For applications where DC precision, low offset drift, and low 1/f noise are the priorities, the OP27E and OP270Z are the appropriate selections.

Frequently Asked Questions (FAQ)
What Is the ADI 5962-9312901MPA and What Is Its Commercial Equivalent?
The 5962-9312901MPA is the military SMD procurement designation for Analog Devices’ AD829SQ, processed to MIL-STD-883B under drawing 5962-93129. It is a high-speed, low-noise op amp with 1.7 nV/√Hz input voltage noise, 230 V/µs slew rate, 750 MHz GBW, user-adjustable external compensation, and broadcast-quality differential phase/gain performance, in an 8-lead hermetic CERDIP package rated for –55°C to +125°C military operation.
What Is the External Compensation and How Is It Set?
The AD829 has two external compensation pins that accept capacitors to adjust the closed-loop frequency response for the intended operating gain. At lower gains (1 to 3), larger compensation capacitors are used to maintain stability. At higher gains (10 to 20), smaller capacitors allow lighter compensation and higher bandwidth. The datasheet provides a table of recommended capacitor values for standard gain settings — the selection is a one-time component choice at the circuit design stage.
How Does the AD829 Compare to the OP27 and OP270 for Military Signal Chain Design?
The 5962-8876401LA OP27E and 5962-8872101PA OP270Z are optimized for DC precision — low offset, low drift, and low 1/f noise — at bandwidths up to 8 MHz. The AD829 sacrifices DC offset performance (1 mV maximum vs 25 µV for the OP27E) for dramatically higher bandwidth, slew rate, and noise performance in the wideband frequency range. Choose the AD829 for video and wideband applications; choose the OP27E or OP270Z for precision DC and low-frequency measurement applications.
Is the AD829SQ/883B Available Without the SMD 5962 Designation?
Yes. The AD829SQ/883B is also available as a commercial 883B-screened part without the formal SMD procurement designation — the same CERDIP package, MIL-STD-883B screening, and –55°C to +125°C temperature rating. For programs that require the formal SMD 5962-93129 procurement path for qualified sources list compliance, the 5962-9312901MPA is the correct designation. For programs where 883B screening and the CERDIP package are sufficient without the SMD number, AD829SQ/883B is a direct procurement alternative.
