Product details
Overview
AD829ARZ-REEL7 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 4.43 MHz - enabling ±1 V output into reverse-terminated 75 Ω cables in broadcast-grade NTSC/PAL systems.
For engineers reviewing the AD829ARZ-REEL7 datasheet, AD829ARZ-REEL7 pinout, AD829ARZ-REEL7 application, or AD829ARZ-REEL7 equivalent, this op amp is selected for demanding high-fidelity video buffering, fast-settling ADC/DAC interface circuits, and low-noise preamplification where dc precision, wide bandwidth, and capacitive-load drive capability are critical.
Technical Context
The AD829ARZ-REEL7 employs Analog Devices' complementary bipolar (CB) process with matched NPN/PNP transistors (fT ≈ 600 MHz), enabling both high transconductance (low 1.7 nV/√Hz input voltage noise) and robust current gain (40,000) in its output stage. Its external compensation pin (CCOMP) supports configurable stability across gains of 1 to 20 via shunt or current-feedback topologies.
Unlike standard voltage-feedback amplifiers, the AD829ARZ-REEL7 maintains >50 MHz bandwidth across gain settings by replacing internal compensation with user-selected CCOMP; it achieves unity-gain stability with 68 pF to ground while delivering 230 V/µs slew rate at gain = −19 with CCOMP = 0 pF. Input symmetry and laser-trimmed offset support dc-coupled video and instrumentation use.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Small-signal bandwidth | 750 MHz at ±15 V supply, gain = 1 - enables wideband RF/IF signal conditioning without peaking. |
| 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 DAC output buffering. |
| Differential gain/phase error | 0.02% / 0.04° at 4.43 MHz into 75 Ω - meets SMPTE RP 168 and EBU R128 broadcast video fidelity requirements. |
| Input voltage noise | 1.7 nV/√Hz at 1 kHz - ensures minimal SNR degradation in low-level sensor preamp or photodiode transimpedance stages. |
| Open-loop gain | ≥85 V/mV into 1 kΩ load - provides <0.001% gain error in closed-loop configurations with 100× feedback ratio. |
| Supply range | ±4.5 V to ±18 V - supports dual-rail operation in legacy industrial systems and modern ±5 V/±12 V video infrastructure. |
| Quiescent current | 5.3 mA typical at ±15 V - balances speed and power efficiency for multi-channel video distribution amplifiers. |
Pinout & Package
AD829ARZ-REEL7 is housed in an 8-lead SOIC (R) package with exposed pad (RoHS-compliant, lead-free). Thermal resistance θJA = 125 °C/W; maximum junction temperature = 150 °C. 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.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8 | Offset Null | Laser-trimmed dc offset adjustment points; connected to 20 kΩ potentiometer wiper for <1 mV residual offset calibration. |
| 2 | Inverting Input (–IN) | Differential input node; symmetrical with +IN; accepts shunt or current-feedback compensation networks. |
| 3 | Noninverting Input (+IN) | Differential input node; matched impedance and noise performance to –IN; used in follower/gain-of-2 configurations. |
| 4 | Negative Supply (–VS) | Ground-referenced negative rail connection; requires local 0.1 µF ceramic decoupling within 5 mm. |
| 5 | Compensation (CCOMP) | Internal frequency compensation node; tied to ground via 68 pF for unity-gain stability or left open for gain ≥20. |
| 6 | Output | Class-AB output stage capable of ±12.2 V swing into 1 kΩ; drives 50–75 Ω coaxial lines directly with <0.1 dB flatness to 30 MHz. |
| 7 | Positive Supply (+VS) | Ground-referenced positive rail connection; requires local 0.1 µF ceramic decoupling within 5 mm. |
Key Features
| Feature | Design Value |
|---|---|
| External CCOMP pin | Enables bandwidth/slew-rate trade-off tuning: 55 MHz @ 230 V/µs (gain = −19) or 71 MHz @ 38 V/µs (gain = 2) via capacitor selection. |
| Video-optimized ac performance | 0.02% differential gain and 0.04° differential phase at PAL/NTSC color subcarriers ensure broadcast-compliant chroma/luma separation. |
| Capacitive load drive | Stable into ≥100 pF loads without external isolation; RC network in output stage eliminates pole-splitting effects up to 100 pF. |
| Low input current noise | 1.5 pA/√Hz - <10% of typical transimpedance amplifiers - preserves dynamic range in high-Z sensor interfaces. |
| Extended temperature range | Rated for −40°C to +125°C operation (AD829A grade), supporting automotive camera modules and industrial vision systems. |

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 |
|---|---|---|---|
| THS3201DR | Higher slew rate (4300 V/µs) but higher input voltage noise (3.3 nV/√Hz); no CCOMP pin; fixed internal compensation. | Better for pulse amplification requiring extreme slew; unsuitable for variable-gain video line drivers needing CCOMP flexibility. | Select THS3201DR only when absolute slew rate >2000 V/µs is mandatory and differential phase/gain specs are secondary. |
| LMH6702MF/NOPB | Lower input voltage noise (1.6 nV/√Hz), similar bandwidth (1.7 GHz), but no offset null pins and higher quiescent current (12.5 mA). | Preferred for ultra-low-noise RF/IF gain blocks; lacks video-optimized ac specs (differential gain/phase not characterized). | Choose LMH6702MF/NOPB for RF signal chains where dc precision and video timing specs are irrelevant. |
Compared with THS3201DR and LMH6702MF/NOPB, AD829ARZ-REEL7 uniquely combines broadcast-grade video fidelity (0.02%/0.04°), user-configurable compensation, and dc precision (1 mV max offset) - making it irreplaceable in professional video infrastructure where both ac and dc performance must coexist.

FAQ
What is the maximum recommended compensation capacitance for stable unity-gain operation of the AD829ARZ-REEL7?
The AD829ARZ-REEL7 requires 68 pF connected between Pin 5 (CCOMP) and ground for unity-gain stability. This configuration yields 66 MHz small-signal bandwidth and 16 V/µs slew rate. Exceeding 68 pF reduces bandwidth and slew rate nonlinearly; values below 68 pF risk instability at gain = 1. The 68 pF value is validated in Table 4 of the Rev. I datasheet under "Shunt Compensation" for follower gain = 1.
Can the AD829ARZ-REEL7 drive a 50 Ω load to ±1 V with broadcast-compliant differential phase performance?
Yes - the AD829ARZ-REEL7 delivers 0.04° differential phase error and 0.02% differential gain error at 4.43 MHz when driving a 75 Ω load, and maintains <0.1 dB gain flatness to 30 MHz into 50 Ω with proper termination. Its ±3.0 V output swing into 150 Ω (per datasheet Table 1) scales to ±1 V into 50 Ω with appropriate gain setting and series matching, meeting SMPTE RP 168 video line driver requirements.
Does the AD829ARZ-REEL7 support single-supply operation?
No - the AD829ARZ-REEL7 is specified exclusively for dual-supply operation from ±4.5 V to ±18 V. Its input common-mode range extends to ±13.8 V at ±15 V supplies, and output swing is symmetrical about ground. Single-supply use violates Absolute Maximum Ratings (Table 2) and causes clipping, rail-to-rail input/output functionality, or undefined behavior per the Rev. I datasheet General Description.
How does the CCOMP pin enable bandwidth optimization in video line driver configurations?
The CCOMP pin (Pin 5) exposes the internal compensation node, allowing users to replace fixed internal capacitance with external CCOMP to tailor bandwidth vs. slew rate. For example, using 0 pF enables 230 V/µs slew rate at gain = −19 (90 ns settling), while 30 pF yields 0.02%/0.04° video performance at 3.58/4.43 MHz. This direct control is essential for balancing transient response and color fidelity in SDI/HDMI transmitter buffers.
Is the AD829ARZ-REEL7 pin-compatible with other op amps in the AD829 family?
Yes - all AD829 variants (AD829JR, AD829AR, AD829AQ, AD829S) share identical 8-lead SOIC (R), PDIP (N), CERDIP (Q), and LCC (E) pinouts per Figure 1 and Figure 2 of the Rev. I datasheet. The AD829ARZ-REEL7 uses the same SOIC footprint and terminal functions as AD829AR, differing only in tape-and-reel packaging and extended temperature rating (−40°C to +125°C).
