Product details
Overview
AD8001ARZ from Analog Devices is a current feedback amplifier optimized for video and high-speed signal conditioning, delivering 880 MHz –3 dB bandwidth (G = +1), 1200 V/µs slew rate, and 0.01% differential gain error at NTSC video loads (RL = 150 Ω). It operates on ±5 V supplies with only 5.5 mA quiescent current and drives up to four 75 Ω back-terminated video lines while maintaining <0.05% differential gain error.
For engineers reviewing the AD8001ARZ datasheet, AD8001ARZ pinout, AD8001ARZ application, or AD8001ARZ equivalent, key selection criteria include its current-feedback architecture enabling gain-independent bandwidth, low distortion (–66 dB SFDR at 5 MHz), and SOIC-8 package compatibility with professional video line driver, A-to-D converter buffer, and RF receiver IF-stage designs.
Technical Context
The AD8001ARZ employs transimpedance linearization to achieve stable video performance across temperature and load variations. Its inverting input presents ~50 Ω impedance, enabling predictable feedback network design with standard resistor values (e.g., RF = 681 Ω for G = +2 in SOIC package).
Unlike voltage-feedback amplifiers, its bandwidth remains largely independent of closed-loop gain-demonstrated by 440 MHz (G = +2) and 880 MHz (G = +1) –3 dB points-while maintaining 0.1 dB flatness to 125 MHz in SOIC configuration. The device supports dual ±3 V to ±6 V supplies or single +12 V operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| –3 dB Bandwidth (G = +1) | 880 MHz - enables full-spectrum fidelity for >400 MSPS sampling systems and baseband video signals up to 100 MHz. |
| Slew Rate | 1200 V/µs - ensures sub-10 ns settling to 0.1% for 2 V step inputs, critical for fast transient response in ADC drivers. |
| Differential Gain Error | 0.01% @ NTSC, RL = 150 Ω - meets broadcast-grade video linearity requirements without external calibration. |
| THD | –65 dBc @ 5 MHz - suppresses harmonic artifacts in RF receiver IF stages and composite video paths. |
| Supply Current | 5.5 mA max @ ±5 V - delivers high-speed performance at only 55 mW total power, suitable for portable and thermally constrained designs. |
| Output Drive | 70 mA - sustains 2.7 V swing into 150 Ω while driving multiple 75 Ω back-terminated loads simultaneously. |
| Input Bias Current | ±25 µA (–IN), ±6 µA (+IN) - allows direct coupling to high-impedance sources without significant DC offset shift. |
Pinout & Package
AD8001ARZ is supplied in an 8-lead SOIC (R-8) package with exposed pad not electrically connected. Pin 1 is marked by a beveled corner or dot; pins are numbered counterclockwise starting from pin 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NC) | No Connect | Internally unconnected; must remain floating per datasheet - no routing or grounding allowed. |
| 2 (–IN) | Inverting Input | Low-impedance (~50 Ω) node requiring short, controlled-impedance trace to feedback resistor; dominant source of high-frequency stability sensitivity. |
| 3 (OUT) | Output | Capable of sourcing/sinking 70 mA; requires local 0.1 µF + 4.7 µF bypassing and series 20 Ω resistor when driving ADC inputs with 10 pF capacitance. |
| 4 (V–) | Negative Supply | Accepts –3 V to –6 V; must be bypassed independently with 0.1 µF ceramic capacitor placed ≤3 mm from pin. |
| 5 (V+) | Positive Supply | Accepts +3 V to +6 V (dual) or +6 V to +12 V (single); same bypassing requirement as V–. |
| 6 (+IN) | Noninverting Input | High-impedance (~10 MΩ) node; used for unity-gain follower or noninverting configurations; sensitive to PCB leakage at high gains. |
| 7 (NC) | No Connect | Internally unconnected; must remain floating - no tie to ground or supply. |
| 8 (NC) | No Connect | Internally unconnected; must remain floating - no tie to ground or supply. |
Key Features
| Feature | Design Value |
|---|---|
| Current Feedback Architecture | Enables gain-flat bandwidth (e.g., 440 MHz at G = +2) without trade-off against stability - eliminates need for gain-compensation networks. |
| Video-Optimized Linearity | 0.01% differential gain / 0.025° differential phase error at NTSC video loads ensures broadcast-compliant color fidelity without post-processing. |
| Low Distortion at High Frequency | –66 dB SFDR at 5 MHz and +33 dBm third-order intercept support clean signal integrity in RF receiver IF chains and wideband data acquisition. |
| Thermal Stability | Input offset drift of 10 µV/°C and supply current variation <0.2 mA over –40°C to +85°C ensure consistent performance across industrial environments. |
| Robust Output Stage | 70 mA output drive with 85 mA short-circuit current enables direct connection to multiple 75 Ω video loads or ADC input networks without external buffers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar current feedback amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMH6702MF/NOPB | Higher 1.8 GHz bandwidth but 12.5 mA supply current; no specified differential gain/phase data for video. | Better suited for RF/IF gain blocks than broadcast video line driving due to lack of NTSC-validated linearity specs. | Select LMH6702MF/NOPB when >1 GHz small-signal bandwidth is required and video differential linearity is not mandated. |
| ADA4817-1ARZ | Faster 1 GHz bandwidth and lower 2.1 nV/√Hz voltage noise, but only 45 mA output drive and no documented 75 Ω multi-load video performance. | Preferred for low-noise photodiode preamps or precision ADC drivers where output current and video linearity are secondary. | Choose ADA4817-1ARZ for ultra-low-noise, high-bandwidth applications with moderate output loading (<30 mA), not multi-load video distribution. |
Compared with LMH6702MF/NOPB and ADA4817-1ARZ, the AD8001ARZ uniquely balances video-grade differential linearity (0.01%/0.025°), 70 mA output drive, and 55 mW power consumption - making it the only option qualified for professional broadcast equipment requiring simultaneous multi-load integrity and thermal efficiency.

FAQ
What is the maximum operating supply voltage for the AD8001ARZ?
The AD8001ARZ supports dual supplies from ±3 V to ±6 V, or a single +12 V supply. Absolute maximum supply voltage is ±6.3 V (12.6 V total), beyond which permanent damage may occur. Operation at ±6 V yields optimal bandwidth and output swing while staying within safe junction temperature limits under typical load conditions.
Can the AD8001ARZ drive multiple 75 Ω back-terminated video loads simultaneously?
Yes, the AD8001ARZ is explicitly characterized to drive up to four 75 Ω back-terminated loads while maintaining 0.05% differential gain and 0.25° differential phase error. This capability is validated in Figure 11 and TPC 12 of the datasheet, confirming its suitability for professional video switchers and distribution amplifiers without external buffering.
What feedback resistor value is recommended for G = +2 in the AD8001ARZ SOIC package?
For the AD8001ARZ (SOIC-8), the recommended feedback resistor for G = +2 is 681 Ω, as specified in Table I on page 14 of the datasheet. This value optimizes bandwidth flatness and minimizes peaking; using 1% tolerance surface-mount resistors is strongly advised to maintain consistency across production lots.
Does the AD8001ARZ require external compensation capacitors for stability?
No, the AD8001ARZ is internally compensated and does not require external capacitors for basic unity-gain or inverting configurations. However, when driving capacitive loads >10 pF (e.g., ADC inputs), a small series resistor (20 Ω) is recommended at the output per Figure 8 and the "Driving Capacitive Loads" section to prevent peaking and ensure monotonic step response.
Is the AD8001ARZ pin-compatible with other members of the AD800x family?
No, the AD8001ARZ is not pin-compatible with AD8002 (dual) or AD8003 (triple) variants. While all share the same SOIC-8 footprint, the AD8001ARZ has three NC pins (1, 7, 8) and dedicated +IN/–IN/OUT/V+/V– terminals, whereas AD8002 uses all eight pins for two independent amplifiers. Board layout must be designed specifically for the AD8001ARZ's pin assignment.
