Product details

Overview

AD829SQ/883B from Analog Devices is a high-speed, low-noise voltage feedback operational amplifier optimized for professional video line driving and precision high-speed data acquisition. 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 4.43 MHz PAL subcarrier-enabling ±1 V output into reverse-terminated 75 Ω cables in broadcast-quality video systems.

For engineers reviewing the AD829SQ/883B datasheet, AD829SQ/883B pinout, AD829SQ/883B application, or AD829SQ/883B equivalent, key selection criteria include external compensation flexibility (CCOMP pin), MIL-STD-883B qualification for extended temperature (−55°C to +125°C), 1.7 nV/√Hz input voltage noise, and verified performance driving capacitive loads and 50–75 Ω transmission lines.

Technical Context

The AD829SQ/883B employs Analog Devices' complementary bipolar (CB) process with matched NPN/PNP transistors (f_T ≈ 600 MHz), enabling both high dc precision (1 mV max offset, 0.3 µV/°C drift) and wide dynamic range. Its folded cascode architecture supports unity-gain stability with 68 pF external compensation while maintaining >50 MHz bandwidth across gains of 1–20.

Two distinct compensation modes are supported: shunt compensation (CCOMP-to-ground) for predictable bandwidth/slew trade-offs, and current feedback compensation (CCOMP between inverting input and compensation pin) for gain-independent bandwidth and enhanced slew rate-e.g., 180 V/µs at 53 MHz with C_COMP = 1 pF and R_F = 3 kΩ.

Key Specifications

Parameter	Value and Actual Design Meaning
Gain Bandwidth Product	750 MHz at ±15 V supply - enables stable closed-loop operation up to 95 MHz with current feedback compensation.
Slew Rate	230 V/µs into 1 kΩ load - supports full-scale 10 V step settling in 90 ns to 0.1%, critical for 10-bit ADC buffering.
Differential Gain Error	0.02% at 4.43 MHz - ensures color fidelity in PAL/SECAM video transmission over 75 Ω coaxial cable.
Input Voltage Noise	1.7 nV/√Hz at 1 kHz - preserves SNR in low-level signal conditioning before high-speed ADCs.
Common-Mode Rejection	120 dB at ±12 V common-mode - maintains accuracy in noisy industrial sensor front-ends.
Operating Temperature Range	−55°C to +125°C - qualified per MIL-STD-883B Method 5005, suitable for aerospace and defense avionics.
Supply Voltage Range	±4.5 V to ±18 V - supports dual-rail operation in legacy ±5 V, ±12 V, and ±15 V systems without redesign.

Pinout & Package

AD829SQ/883B is housed in an 8-lead CERDIP (Q) package with hermetic ceramic/metal construction, rated for −55°C to +125°C operation and compliant with MIL-STD-883B screening. Pin 1 and Pin 8 are offset null terminals; Pin 5 is the external compensation node (CCOMP); Pin 4 and Pin 7 are power rails (−VS, +VS); Pin 2 and Pin 3 are differential inputs (−IN, +IN); Pin 6 is the output.

Pin/Terminal	Circuit Role	Design Meaning
1, 8	Offset Null	Laser-trimmed potentiometer connection points for manual input offset voltage adjustment (±1 mV trim range).
2	Inverting Input (−IN)	High-impedance NPN differential pair input; used as summing node in inverting configurations and current feedback compensation path.
3	Noninverting Input (+IN)	Matched high-impedance input; symmetrical layout minimizes input capacitance imbalance (1.5 pF common-mode, 5 pF differential).
4	Negative Supply (−VS)	Power rail connection; internal biasing requires stable ±4.5 V to ±18 V dual supply; thermal derating applies above 25°C ambient.
5	Compensation (CCOMP)	Access point to internal frequency compensation node; determines stability, bandwidth, and slew rate via external capacitor or feedback network.
6	Output	Complementary emitter-follower output stage; drives ±3 V into 150 Ω or ±12.2 V into 500 Ω at ±15 V supplies with <0.1% settling error.
7	Positive Supply (+VS)	Power rail connection; decoupling with 0.1 µF ceramic capacitor recommended adjacent to pin for high-frequency PSRR maintenance.

Key Features

Feature	Design Value
External Compensation Flexibility	CCOMP pin enables user-selectable bandwidth/slew trade-offs: 66 MHz @ 16 V/µs (68 pF) or 55 MHz @ 230 V/µs (0 pF) - adapts to load, supply, and signal integrity requirements.
Video-Optimized AC Performance	0.04° differential phase and 0.02% differential gain at NTSC/PAL/SECAM subcarriers ensure broadcast-grade color reproduction in SD/HD analog video distribution.
Capacitive Load Drive Capability	Stable operation into ≥100 pF loads without external isolation resistors - simplifies interface to ADC input capacitance or long PCB traces.
MIL-STD-883B Qualification	Screened per Method 5005 (temperature cycling, burn-in, hermeticity) and Method 2019 (electrical test) - guarantees reliability in mission-critical military/aerospace applications.
Low Input Current Noise	1.5 pA/√Hz - less than 10% of typical transimpedance amplifiers - reduces Johnson noise contribution in high-Z sensor interfaces.

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
AD829ARZ	Commercial-grade SOIC-8; −40°C to +125°C; no MIL-STD-883B screening; same electrical specs except wider offset voltage (0.5 mV max).	Not qualified for space or defense programs requiring hermetic packaging and radiation-hardened test flow.	Select AD829ARZ only for cost-sensitive industrial or test equipment where extended temperature and screening are not mandated.
LMH6702MF/NOPB	1.7 GHz GBW, 3200 V/µs slew rate, but higher input voltage noise (2.1 nV/√Hz); no CCOMP pin; fixed internal compensation.	Lacks external compensation flexibility and video-optimized differential phase/gain specs; unsuitable for analog video line driving.	Choose LMH6702MF/NOPB only when maximum small-signal bandwidth (>500 MHz) is prioritized over video fidelity or dc precision.

Compared with AD829ARZ and LMH6702MF/NOPB, the AD829SQ/883B uniquely combines MIL-qualified reliability, CCOMP-based bandwidth tuning, and broadcast-grade video performance-making it irreplaceable in defense avionics and broadcast infrastructure where all three attributes are simultaneously required.

FAQ

What is the operating temperature range of the AD829SQ/883B?

The AD829SQ/883B is qualified per MIL-STD-883B with an operating temperature range of −55°C to +125°C. This specification is validated through temperature cycling, burn-in, and parametric testing per Method 5005 and Method 2019. The CERDIP package provides hermetic sealing essential for aerospace and defense deployments where thermal shock and long-term reliability are mission-critical. AD829SQ/883B maintains full electrical performance-including 230 V/µs slew rate and 0.02% differential gain-across this entire range.

How does the CCOMP pin on the AD829SQ/883B affect bandwidth and stability?

The CCOMP pin on the AD829SQ/883B provides direct access to the internal compensation node, enabling two distinct stabilization methods: shunt compensation (capacitor to ground) for predictable gain-bandwidth trade-offs, and current feedback compensation (capacitor between −IN and CCOMP) for gain-independent bandwidth. With 0 pF CCOMP, AD829SQ/883B achieves 230 V/µs slew rate and 55 MHz bandwidth at gain = 20; with 68 pF, it delivers 16 V/µs and 66 MHz bandwidth at unity gain. AD829SQ/883B remains stable for noise gains ≥20 without external components.

Is the AD829SQ/883B suitable for driving 75 Ω video cables, and what performance is guaranteed?

Yes, the AD829SQ/883B is explicitly characterized for driving reverse-terminated 75 Ω video cables. At ±15 V supplies, it delivers 0.02% differential gain error and 0.04° differential phase error at 4.43 MHz (PAL/SECAM subcarrier) and 3.58 MHz (NTSC), meeting broadcast-grade video specifications. Its ±3 V output swing into 150 Ω and ability to drive capacitive loads without peaking make it ideal for SD/HD analog video line drivers. AD829SQ/883B maintains these metrics across its full −55°C to +125°C operating range.

What is the input voltage noise density of the AD829SQ/883B, and how does it impact low-level signal conditioning?

The AD829SQ/883B has an input voltage noise density of 1.7 nV/√Hz at 1 kHz, measured under ±15 V supplies. This low noise floor preserves signal-to-noise ratio in precision front-end applications such as sensor signal conditioning and high-speed ADC buffering. When driving a 500 Ω source impedance, total integrated noise remains below 1.2 µV RMS over 10 MHz bandwidth-critical for maintaining ≥68 dB SNR in 10-bit data acquisition systems. AD829SQ/883B's 1.5 pA/√Hz input current noise further minimizes contribution from high-impedance sources.

Does the AD829SQ/883B require external offset nulling, and how is it implemented?

The AD829SQ/883B includes dedicated Offset Null pins (1 and 8) for manual input offset voltage trimming. A 20 kΩ potentiometer connected between these pins-with wiper to −VS-allows adjustment of input offset voltage within ±1 mV. This capability is essential in dc-coupled instrumentation amplifier topologies where residual offset directly impacts measurement accuracy. The laser-trimmed input stage ensures initial offset remains ≤0.5 mV over temperature, and AD829SQ/883B's 0.3 µV/°C drift minimizes re-trimming needs across its −55°C to +125°C range.
