Product details
Overview
AD8011ARZ-REEL from Analog Devices is a current feedback amplifier optimized for single-supply 5 V operation, delivering 300 MHz –3 dB bandwidth (G = +1), 2000 V/µs slew rate, and 29 ns settling time to 0.1%. It serves as a low-power, high-speed buffer and driver in professional video signal chains and high-resolution ADC interfaces.
For engineers reviewing the AD8011ARZ-REEL datasheet, AD8011ARZ-REEL pinout, AD8011ARZ-REEL application, or AD8011ARZ-REEL equivalent, key selection criteria include its 1 mA quiescent current, differential gain error of 0.02%, NTSC-compliant video performance, and SOIC-8 package compatibility with space-constrained portable systems.
Technical Context
The AD8011ARZ-REEL implements a two-stage complementary current feedback architecture-distinct from traditional single-stage Nelson designs-to achieve high gain-bandwidth product with low distortion and load drive capability. Its open-loop transresistance exceeds 800 kΩ, and it maintains stable operation across ±1.5 V to ±6 V dual supplies or +3 V to +12 V single supply.
It features a wide input common-mode range (1.2 V to 3.8 V on +5 V supply), rail-to-rail output swing (0.9 V to 4.1 V), and intrinsic stability when driving capacitive loads up to 5 pF-provided series damping resistance is applied per layout guidelines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| –3 dB Bandwidth (G = +1) | 300 MHz - enables full HD video signal amplification without attenuation at baseband |
| Slew Rate (G = +2) | 2000 V/µs - supports fast transient response for 10-bit ADC sampling at ≥20 MSPS |
| Settling Time to 0.1% | 29 ns - ensures accurate sampling window closure for high-speed data acquisition |
| Differential Gain Error | 0.02% @ NTSC, RL = 1 kΩ - meets broadcast-grade video fidelity requirements |

Pinout & Package
AD8011ARZ-REEL is housed in an 8-lead SOIC (Small Outline Integrated Circuit) package, RoHS-compliant and rated for industrial temperature range (–40°C to +85°C). The package footprint matches JEDEC MS-012AC, with 1.27 mm lead pitch and 5.0 mm × 6.2 mm body dimensions.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NC) | No Connect | Internally unconnected; must remain floating or grounded per layout best practice |
| 2 (+IN) | Noninverting Input | High-impedance node (450 kΩ) with 2.3 pF capacitance; bias voltage sets DC operating point |
| 3 (–IN) | Inverting Input | Current-summing node; requires matched trace length and impedance for optimal video flatness |
| 4 (V–) | Negative Supply | Connected to ground in single-supply mode; decoupling capacitor required within 1 cm |
| 5 (OUT) | Amplifier Output | Low-output-impedance (0.1–0.3 Ω) driver capable of sourcing/sinking 15–30 mA into 150 Ω loads |
| 6 (NC) | No Connect | Internally unconnected; no external connection permitted |
| 7 (V+) | Positive Supply | Accepts +3 V to +12 V; 0.1 µF ceramic + 10 µF tantalum decoupling mandatory |

Equivalent & Alternatives
The following parts are listed as comparable options for similar current feedback amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMH6702MA/NOPB | Higher 1.8 GHz bandwidth but 12.5 mA quiescent current; SOIC-8 package | Better suited for RF IF amplification; excessive power for battery-powered video gear | Select when >500 MHz bandwidth is required and thermal/power budget allows |
| THS3201D | 2.1 GHz bandwidth, 12.5 mA IQ, 5000 V/µs slew rate; SOIC-8 | Optimized for wideband communications; lacks NTSC-specific video specs | Prefer for high-frequency instrumentation where differential phase/gain specs are secondary |
Compared with LMH6702MA/NOPB and THS3201D, the AD8011ARZ-REEL delivers optimal trade-off between video-grade linearity (0.02% DG), ultra-low power (1.15 mA), and sufficient bandwidth (300 MHz) for portable professional imaging-without over-spec'ing power or cost.

FAQ
What is the maximum supply voltage rating for AD8011ARZ-REEL?
The AD8011ARZ-REEL has an absolute maximum supply voltage rating of 12.6 V. It operates reliably across +3 V to +12 V in single-supply mode and ±1.5 V to ±6 V in dual-supply configurations. Exceeding 12.6 V risks permanent damage, and operation above ±6 V or +12 V voids parametric guarantees per the datasheet Absolute Maximum Ratings table.
Does AD8011ARZ-REEL support rail-to-rail input and output operation?
The AD8011ARZ-REEL does not provide rail-to-rail input operation: its input common-mode range is specified as 1.2 V to 3.8 V on a +5 V supply. However, its output swing reaches 0.9 V to 4.1 V-near rail-to-rail-enabling direct interfacing with single-supply ADCs like the AD876 without level-shifting circuitry.
Can AD8011ARZ-REEL drive a 150 Ω video load while maintaining NTSC specifications?
Yes, the AD8011ARZ-REEL maintains 0.02% differential gain and 0.3° differential phase error into a 150 Ω load at G = +2, as verified in the Single Supply specifications table. Its 30 mA output current capability and low 0.3 Ω output resistance ensure stable drive into standard video termination impedances without gain droop or timing skew.
Is AD8011ARZ-REEL pin-compatible with other SOIC-8 current feedback amplifiers?
No, AD8011ARZ-REEL is not pin-compatible with generic SOIC-8 current feedback amplifiers. Its pin 1, 6, and 8 are NC (no connect), unlike most competitors that assign active functions to those pins. Substitution requires PCB layout revision; always verify pin mapping against the functional block diagram before replacement.
What decoupling is recommended for stable AD8011ARZ-REEL operation?
Analog Devices specifies 0.1 µF ceramic capacitor placed within 1 cm of pins 4 (V–) and 7 (V+), plus a 10 µF bulk capacitor (tantalum or ceramic) near the SOIC-8 footprint. This dual-tier decoupling suppresses high-frequency supply noise and prevents oscillation, especially critical given the AD8011ARZ-REEL's 300 MHz bandwidth and sensitivity to parasitic inductance.
