Product details
Overview
AD8004ARZ-14 from Analog Devices is a quad current-feedback amplifier optimized for high-speed video and imaging signal conditioning, delivering 250 MHz –3 dB bandwidth (G = +1), 3000 V/µs slew rate, and 21 ns settling time to 0.1%, with operation on single +5 V supply in industrial temperature range (–40°C to +85°C).
For engineers reviewing the AD8004ARZ-14 datasheet, AD8004ARZ-14 pinout, AD8004ARZ-14 application, or AD8004ARZ-14 equivalent, key selection criteria include differential gain error (0.04%), output drive capability (±3.9 V swing into 150 Ω), low distortion (–78 dBc THD at 5 MHz), and SOIC-14 package compatibility with video switchers and active filter designs.
Technical Context
The AD8004ARZ-14 employs a two-stage current-feedback architecture enabling constant bandwidth vs. gain and high slew rate independent of closed-loop configuration. Its transimpedance open-loop gain (170–290 kΩ) dominates frequency response at low gains, while second-stage buffering reduces load-dependent distortion.
It supports both inverting and noninverting configurations with recommended RF values (e.g., 1.10 kΩ for G = +2) to optimize flatness or bandwidth trade-offs. Input common-mode voltage range extends to ±3.2 V, and input impedance is asymmetric: 2 MΩ at +IN, 50 Ω at –IN - critical for proper feedback network design.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| –3 dB Bandwidth | 250 MHz at G = +1: enables full HD video signal amplification without attenuation up to 1080p/60 timing. |
| Slew Rate | 3000 V/µs: supports fast transient handling for pulse-based imaging and digital-to-analog reconstruction. |
| Settling Time | 21 ns to 0.1%: meets timing requirements for 20 MSPS ADC drivers like AD876 without sampling error. |
| Differential Gain Error | 0.04% at NTSC, RL = 150 Ω: preserves color fidelity in broadcast-quality video routing systems. |
| Output Current | ±50 mA: drives 150 Ω video loads directly without external buffers, reducing BOM count. |
| Supply Range | +4 V to +12 V single supply: compatible with standard 5 V logic rails and portable battery-powered imaging modules. |
| Quiescent Current | 14–17 mA total (3.5 mA/amplifier): balances speed and power efficiency for quad-channel portable applications. |
Pinout & Package
AD8004ARZ-14 is housed in a 14-lead SOIC (R-14) package per JEDEC MS-012AB, with 8.75 mm × 4.00 mm footprint, 1.27 mm lead pitch, and 1.75 mm max height. Pin 1 is marked by notch or dot; device operates with exposed pad unconnected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Output A | Amplifier A output; capable of ±50 mA sink/source into 150 Ω load with 3.9 V p-p swing. |
| 2 | Inverting Input A | Low-impedance (50 Ω) current-summing node; requires precise RF placement to minimize parasitic capacitance. |
| 3 | Noninverting Input A | High-impedance (2 MΩ) input; common-mode range extends to ±3.2 V for level-shifting flexibility. |
| 4 | +VS | Positive supply rail for all four amplifiers; bypass with 0.1 µF ceramic + 4.7–10 µF tantalum near pin. |
| 5 | Noninverting Input B | Independent high-Z input for second amplifier; shares no internal nodes with Channel A. |
| 6 | Inverting Input B | Low-Z summing node for Channel B; layout symmetry critical to match Channel A performance. |
| 7 | Output B | Channel B output; identical specs to Pin 1; supports independent gain configuration. |
| 8 | –VS | Negative supply or ground reference; must be low-impedance return path for all four channels. |
| 9 | Output C | Third amplifier output; fully isolated; enables triple-signal-path architectures (e.g., RGB video). |
| 10 | Inverting Input C | Low-Z input for Channel C; decoupling and trace length matching required for crosstalk < –69 dB. |
| 11 | Noninverting Input C | High-Z input for Channel C; supports DC-coupled biasing in active filter topologies. |
| 12 | +VS | Second +VS connection; electrically tied internally; improves supply current distribution. |
| 13 | Noninverting Input D | Fourth amplifier input; enables quad-channel simultaneous sampling in multi-sensor imaging. |
| 14 | Output D | Final channel output; supports independent termination; used in 4× video multiplexing or parallel ADC buffering. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed current-feedback amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD8003ARZ | Triple-channel version; identical specs per channel but lacks fourth amplifier. | Suitable where only three signal paths needed (e.g., RGB without sync); saves board space vs. quad. | Select when BOM consolidation or reduced channel count lowers system cost without sacrificing per-channel performance. |
| LMH6703MA | Single-channel, higher slew rate (4000 V/µs), wider bandwidth (1.3 GHz), but higher quiescent current (12 mA/channel). | Better for ultra-high-speed pulse applications (e.g., time-of-flight sensors), not optimized for video flatness or multi-channel matching. | Choose for single-path >500 MHz applications where power and channel density are secondary to raw speed. |
Compared with AD8004ARZ-14, AD8003ARZ offers identical per-channel performance in a smaller footprint but lacks the fourth channel needed for quad-sensor or RGB+sync systems; LMH6703MA trades channel count and video-optimized flatness for extreme bandwidth and slew rate in single-path applications.

FAQ
What is the operating temperature range for the AD8004ARZ-14?
The AD8004ARZ-14 is rated for industrial operation from –40°C to +85°C, as confirmed in the Ordering Guide and Absolute Maximum Ratings table. This range applies to the R-14 SOIC package variant and is validated across all electrical specifications including bandwidth, slew rate, and differential gain error under thermal stress.
Does the AD8004ARZ-14 support single-supply operation?
Yes, the AD8004ARZ-14 is fully specified for single +5 V supply operation, with input common-mode range extending to ±3.2 V and output swing reaching 0.9 V to 4.1 V into 150 Ω. It also supports dual supplies from ±2.0 V to ±6.0 V, maintaining identical dynamic performance across both configurations.
What is the recommended feedback resistor for G = +2 configuration with the AD8004ARZ-14?
The datasheet specifies 1.10 kΩ as the nominal RF value for G = +2 in noninverting configuration to achieve optimal frequency response and minimal peaking. Table I confirms this value yields 110 MHz small-signal bandwidth and < 0.1 dB peaking at ±5 V supply, validated in TPC 9 and Figure 8.
Can the AD8004ARZ-14 drive a 150 Ω video load directly?
Yes, the AD8004ARZ-14 delivers ±50 mA output current and achieves ±3.9 V output swing into 150 Ω, meeting SMPTE/NTSC video drive requirements. Its 0.04% differential gain and 0.10° phase error at RL = 150 Ω are measured under these exact conditions using RF = 1.21 kΩ, confirming direct-drive capability without external buffers.
Is the AD8004ARZ-14 RoHS compliant?
Yes, the "Z" suffix in AD8004ARZ-14 denotes RoHS-compliant packaging per Analog Devices' ordering nomenclature. The datasheet's Ordering Guide explicitly states "1 Z = RoHS Compliant Part", and the R-14 package uses lead-free terminations and halogen-free molding compound.
