Product details
Overview
AD829SE/883B from Analog Devices is a high-speed, low-noise voltage-feedback operational amplifier optimized for professional video line driving and precision analog signal conditioning. It delivers 230 V/µs slew rate, 750 MHz gain bandwidth (±15 V), 0.02% differential gain error, and 0.04° differential phase error at 3.58/4.43 MHz - enabling broadcast-grade NTSC/PAL/SECAM signal integrity into reverse-terminated 75 Ω cables.
For engineers reviewing the AD829SE/883B datasheet, AD829SE/883B pinout, AD829SE/883B application, or AD829SE/883B equivalent, key selection criteria include external compensation flexibility (CCOMP pin), MIL-STD-883B qualification for aerospace/military use, ±5 V to ±15 V dual-supply operation, and verified performance in high-settling-speed ADC/DAC interface circuits.
Technical Context
The AD829SE/883B employs Analog Devices' complementary bipolar (CB) process with matched NPN/PNP transistors (fT ≈ 600 MHz), enabling simultaneous high slew rate and low input voltage noise (1.7 nV/√Hz). Its externally accessible CCOMP pin supports shunt or current-feedback compensation schemes, allowing bandwidth optimization across gains of 1–20 while maintaining stability.
Unlike internally compensated op amps, the AD829SE/883B achieves unity-gain stability only with ≥68 pF on CCOMP, but operates uncompensated (CCOMP = 0 pF) at noise gains ≥20. Its symmetrical inputs, laser-trimmed offset (≤0.5 mV over temperature), and 120 dB CMRR/PSRR support precision DC-coupled video and data acquisition systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 750 MHz at ±15 V - enables stable closed-loop operation up to 55 MHz at G = 20 with minimal peaking. |
| Slew Rate | 230 V/µs into 1 kΩ - supports full-scale 10 V step settling in 90 ns to 0.1%, critical for 10-bit DAC output buffering. |
| Differential Gain Error | 0.02% at 3.58/4.43 MHz - ensures color fidelity in broadcast video transmission over 75 Ω coaxial cable. |
| Input Voltage Noise | 1.7 nV/√Hz at 1 kHz - preserves SNR in low-level preamplifier stages preceding ADCs or RF mixers. |
| Input Offset Voltage | ≤0.5 mV over temperature - eliminates need for AC coupling in DC-coupled video line drivers and instrumentation front ends. |
| Supply Range | ±4.5 V to ±18 V - supports legacy ±5 V logic interfacing and high-voltage signal chain designs without level shifting. |
| Quiescent Current | 5.3 mA at ±15 V - balances speed and power efficiency in multi-channel video processing modules. |
Pinout & Package
AD829SE/883B is supplied in an 8-lead CERDIP (Q) package rated for −55°C to +125°C operation and compliant with MIL-STD-883B Class B screening. The hermetically sealed ceramic package ensures long-term reliability in high-reliability aerospace and defense applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8 | OFFSET NULL | Laser-trimmable pins for external nulling of input offset voltage; required for sub-mV DC accuracy in precision video gain blocks. |
| 2 | −IN | Inverting input node; symmetrical with +IN for balanced layout and minimized common-mode distortion in differential configurations. |
| 3 | +IN | Noninverting input node; low input capacitance (5 pF diff, 1.5 pF cm) minimizes high-frequency phase shift in video feedback networks. |
| 4 | −VS | Negative supply rail connection; must be decoupled with 0.1 µF ceramic capacitor near pin for stable high-frequency PSRR. |
| 5 | CCOMP | External compensation node; direct access enables bandwidth/slew trade-off tuning via capacitor selection (0–68 pF). |
| 6 | OUTPUT | Class-AB output stage capable of ±3.0 V swing into 150 Ω - drives back-terminated 75 Ω video loads to ±1 V at termination point. |
| 7 | +VS | Positive supply rail connection; internal PTAT biasing ensures stable quiescent current across −55°C to +125°C operating range. |
Key Features
| Feature | Design Value |
|---|---|
| External CCOMP pin | Enables user-selectable bandwidth/slew rate trade-off: 55 MHz @ 230 V/µs (G=20, CCOMP=0 pF) or 66 MHz @ 16 V/µs (G=1, CCOMP=68 pF). |
| MIL-STD-883B qualification | Guarantees performance under shock, vibration, temperature cycling, and burn-in per Method 5005 - mandatory for flight-critical avionics signal conditioning. |
| Differential phase/gain performance | 0.04°/0.02% at PAL/NTSC subcarriers ensures <0.1 dB gain flatness to 30 MHz in 75 Ω video line drivers without post-compensation EQ. |
| High open-loop gain | ≥85 V/mV into 500 Ω load - maintains loop accuracy and THD < −70 dB in closed-loop G=10 video amplifiers at 5 MHz. |
| Low input current noise | 1.5 pA/√Hz - reduces Johnson noise contribution in high-Z sensor interfaces and photodiode transimpedance stages. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMH6723MF/NOPB | Higher 1.8 GHz GBW but higher 2.9 nV/√Hz noise; no CCOMP pin; not MIL-qualified. | Preferred for wideband RF IF amplification where noise floor dominates; unsuitable for MIL-STD-883B programs. | Select LMH6723MF/NOPB only when maximum small-signal bandwidth is prioritized over video fidelity and military qualification. |
| THS3201DGN | Current-feedback architecture; 900 MHz BW, 3000 V/µs slew; requires careful feedback resistor selection; no offset null pins. | Better for ultra-high-speed pulse amplification (e.g., LIDAR receivers); lacks differential phase/gain specs for video. | Choose THS3201DGN for transient-critical applications needing >1000 V/µs slew; avoid where DC precision or video compliance is required. |
Compared with LMH6723MF/NOPB and THS3201DGN, AD829SE/883B uniquely combines MIL-STD-883B qualification, external compensation flexibility, and broadcast-video-validated differential gain/phase performance - making it irreplaceable in space-qualified video subsystems and high-reliability test equipment.

FAQ
What is the operating temperature range for AD829SE/883B?
The AD829SE/883B is qualified per MIL-STD-883B with an operating temperature range of −55°C to +125°C. This extended range is validated through temperature cycling, burn-in, and parametric testing per Method 5005, ensuring reliability in spacecraft, missile guidance, and high-altitude avionics systems where ambient extremes are encountered. The AD829SE/883B maintains specified slew rate, bandwidth, and offset voltage performance across this full range.
Does AD829SE/883B require external compensation capacitors?
Yes, AD829SE/883B requires external compensation on the CCOMP pin for stable operation at gains below 20. For unity-gain configurations, a 68 pF capacitor from Pin 5 to ground is mandatory to achieve 66 MHz bandwidth and 16 V/µs slew rate. At G ≥ 20, AD829SE/883B is stable with CCOMP left unconnected (0 pF), delivering 230 V/µs slew rate and 55 MHz bandwidth. The CCOMP pin enables precise bandwidth/slew optimization per application.
How does AD829SE/883B differ from commercial-grade AD829AR?
AD829SE/883B differs from AD829AR in three critical ways: (1) hermetic 8-lead CERDIP packaging vs. plastic SOIC; (2) full MIL-STD-883B Class B screening including thermal shock, mechanical shock, and life test; and (3) guaranteed −55°C to +125°C operation with parametric limits tightened for military use. The AD829SE/883B also features enhanced ESD robustness and lot traceability required for defense prime contracts.
Can AD829SE/883B drive 75 Ω video loads directly?
Yes, AD829SE/883B is explicitly characterized to drive reverse-terminated 75 Ω video loads with ±1 V output at the termination point. Its ±3.0 V output swing into 150 Ω (per datasheet Table 1) provides sufficient headroom for standard 1 Vp-p composite video levels. When configured as a gain-of-1 line driver with proper source termination, AD829SE/883B achieves 0.02% differential gain and 0.04° differential phase at 4.43 MHz - meeting SMPTE 253M broadcast specifications.
What is the purpose of the OFFSET NULL pins on AD829SE/883B?
The OFFSET NULL pins (1 and 8) on AD829SE/883B provide access to the internal laser-trimmed offset adjustment network. Connecting a 20 kΩ potentiometer between these pins and grounding its wiper allows fine-tuning of input offset voltage to <0.1 mV - essential for DC-coupled video gain blocks and precision instrumentation where residual offset causes baseline drift or color tilt. This feature is retained from the commercial AD829 and fully functional in the SE/883B variant.
