Product details
Overview
AD8014ARZ from Analog Devices is a high-speed current-feedback operational amplifier optimized for low-power, wideband signal conditioning in battery-powered and video systems. It delivers 400 MHz –3 dB bandwidth (G = +1), 4000 V/µs slew rate, 24 ns settling time to 0.1%, and operates from +4.5 V to +12 V supplies. Its 3.5 nV/√Hz input voltage noise and 5 pA/√Hz input current noise make it suitable for photodiode preamplification and A-to-D driver applications.
For engineers reviewing the AD8014ARZ datasheet, AD8014ARZ pinout, AD8014ARZ application, or AD8014ARZ equivalent, this page provides verified technical context, SOIC-8 package mapping, real-world video and photodiode use cases, and two validated alternative parts with documented functional trade-offs.
Technical Context
The AD8014ARZ uses a proprietary current-feedback architecture enabling simultaneous high bandwidth and low power consumption. Its transimpedance gain stage provides low input impedance at the inverting node (<100 Ω), making it ideal for photodiode current-to-voltage conversion without degrading pulse fidelity.
It features stable operation with minimal external compensation: feedback resistor selection directly controls bandwidth and gain (e.g., RF = 500 Ω yields ~170 MHz large-signal BW at G = +2), while maintaining fast overload recovery (60 ns) and low distortion (–70 dB THD @ 5 MHz).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| –3 dB Bandwidth (G = +1) | 400 MHz - supports full HD video signal amplification up to 1080p60 without attenuation |
| Slew Rate | 4000 V/µs - enables clean 2 V step response with <2.8 ns rise time, critical for fast-settling ADC drivers |
| Settling Time (0.1%) | 24 ns - ensures accurate sampling in high-speed data acquisition systems with >20 MSPS throughput |
| Input Voltage Noise | 3.5 nV/√Hz - preserves SNR in low-level photodiode preamp stages where signal currents are sub-µA |
| Quiescent Current | 1.15 mA max @ +5 V - allows integration into portable instruments with strict 5–10 mA total analog rail budgets |
| Supply Range | +4.5 V to +12 V - supports single-supply industrial systems and dual-supply precision video circuits |
| Output Drive | ±3.8 V swing into 1 kΩ, 50 mA output current - drives 75 Ω or 50 Ω terminated video lines directly |
Pinout & Package
AD8014ARZ is packaged in an 8-lead SOIC_N (R-8) compliant with JEDEC MS-012-AA, with 1.27 mm lead pitch and exposed pad not present. Pin 1 is marked by a beveled corner or dot; pins are numbered counterclockwise.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No Connect | Internally unconnected; must remain floating or grounded per layout best practice |
| 2 | No Connect | Internally unconnected; no routing or soldering required |
| 3 | Inverting Input (–IN) | Low-impedance current-summing node (<100 Ω); connects to photodiode cathode or feedback network |
| 4 | Negative Supply (–VS) | Accepts ground or negative rail; required even in single-supply configurations using split-rail biasing |
| 5 | No Connect | Internally unconnected; leave unpopulated |
| 6 | Non-inverting Input (+IN) | High-impedance voltage reference node (450 kΩ); used for DC bias setting in single-supply video drivers |
| 7 | No Connect | Internally unconnected; no electrical function |
| 8 | Output (VOUT) | Capable of driving ≥50 mA into 150 Ω loads; requires series resistor when driving >40 pF capacitive loads |
Key Features
| Feature | Design Value |
|---|---|
| Current-feedback topology | Enables bandwidth scaling independent of closed-loop gain-400 MHz at G = +1 drops only to 120 MHz at G = –1 |
| Low-noise photodiode interface | 3.5 nV/√Hz voltage noise + 5 pA/√Hz current noise minimizes Johnson/Nyquist-limited SNR degradation |
| Video-optimized line driving | Differential gain error ≤0.06% and phase error ≤0.03° at NTSC frequencies enable broadcast-grade composite video |
| Fast overload recovery | 60 ns return to linear operation after ±4 V input overdrive prevents pulse pile-up in burst-mode optical receivers |
| Single-supply compatibility | Operates from +4.5 V to +12 V with input common-mode range extending to within 1.2 V of rails |

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 |
|---|---|---|---|
| ADA4817-1ARMZ | Lower input voltage noise (2.1 nV/√Hz), higher supply current (12.5 mA), 1 GHz bandwidth | Better for ultra-low-noise preamps but unsuitable for power-constrained portable designs | Select ADA4817-1ARMZ only when noise dominates over power budget; AD8014ARZ remains optimal for <2 mA systems |
| LMH6702MA/NOPB | Higher slew rate (5700 V/µs), wider supply range (±5 V to ±6 V), 1.6 GHz bandwidth, no RoHS-compliant SOIC-8 variant | Preferred for >1 GHz RF instrumentation; lacks AD8014ARZ's video-optimized distortion specs | Choose LMH6702MA/NOPB for RF test gear requiring >1 GHz small-signal BW; AD8014ARZ preferred for video/photodiode where RoHS and cost matter |
Compared with ADA4817-1ARMZ and LMH6702MA/NOPB, AD8014ARZ uniquely balances 400 MHz bandwidth, 1.15 mA quiescent current, RoHS-compliant SOIC-8 packaging, and video-grade distortion performance-making it the only option meeting all four criteria for cost-sensitive, battery-powered, and broadcast video applications.

FAQ
What is the maximum capacitive load the AD8014ARZ can drive without instability?
The AD8014ARZ can safely drive up to 40 pF capacitive load with 30% overshoot when configured with RL = 1 kΩ and RF = 500 Ω. For larger loads, a series resistor (e.g., 10–50 Ω) must be added between the output and the capacitor to maintain stability and preserve settling behavior. This limitation stems from its current-feedback architecture's sensitivity to output node reactance.
Does the AD8014ARZ support true single-supply operation with rail-to-rail input and output?
The AD8014ARZ does not provide rail-to-rail input or output swing. Its input common-mode range extends to within 1.2 V of the negative rail and 1.1 V of the positive rail; output swing is typically ±3.8 V into 1 kΩ with ±5 V supplies. For true single-supply use, a DC bias must be applied to the non-inverting input, and output coupling may be required.
How does the AD8014ARZ compare to voltage-feedback op amps in photodiode preamp applications?
Unlike voltage-feedback op amps, the AD8014ARZ offers low inverting-input impedance (<100 Ω), minimizing the effect of photodiode junction capacitance on bandwidth. This results in superior pulse fidelity and faster settling-critical for high-speed optical storage. Its 3.5 nV/√Hz noise and 24 ns settling make AD8014ARZ more effective than most voltage-feedback alternatives in >20 MHz photodiode front-ends.
Is the AD8014ARZ pin-compatible with other SOIC-8 op amps like the AD8001 or AD8009?
No, the AD8014ARZ is not pin-compatible with AD8001 or AD8009. Its pinout (NC/NC/–IN/–VS/NC/+IN/NC/VOUT) differs significantly from standard voltage-feedback SOIC-8 op amps, which typically place +IN on pin 3 and –IN on pin 2. Layout reuse is not possible without redesign.
What is the recommended feedback resistor value for G = +2 video driver configuration?
For G = +2 operation in video applications, Analog Devices specifies RF = 500 Ω with RG = 500 Ω. This yields 170–210 MHz large-signal bandwidth (VO = 2 V p-p) and meets NTSC differential gain/phase requirements (<0.06%/0.03°). Using RF = 1 kΩ reduces bandwidth to ~130 MHz but improves harmonic distortion at lower frequencies.
