Analog Devices Inc. AD8007AKSZ-REEL7

Overview

AD8007AKSZ-REEL7 from Analog Devices is a single-channel, current-feedback operational amplifier optimized for ultralow distortion and high-speed signal conditioning in precision analog front-ends. It delivers −83 dBc second harmonic distortion at 20 MHz, 650 MHz −3 dB bandwidth (G = +1), 1000 V/μs slew rate, and 2.7 nV/√Hz input voltage noise - enabling high-fidelity IF/baseband amplification in instrumentation and data acquisition systems.

For engineers reviewing the AD8007AKSZ-REEL7 datasheet, AD8007AKSZ-REEL7 pinout, AD8007AKSZ-REEL7 application, or AD8007AKSZ-REEL7 equivalent, key selection criteria include its SC70-5 package footprint, ±5 V or single 5 V supply operation, 9 mA quiescent current, and verified performance in A/D driver and DAC buffer roles with <0.01% differential phase error on NTSC video signals.

Technical Context

The AD8007AKSZ-REEL7 implements a modified current-feedback architecture using Analog Devices' second-generation XFCB process, featuring low-distortion signal mirrors (M1/M2) and active imbalance compensation (IDI/IDO currents) to suppress even-order harmonics. Its high-Z input stage enables wide common-mode range (−3.9 V to +3.9 V) and low input capacitance (1 pF).

Unlike voltage-feedback op amps, it maintains stable gain-bandwidth trade-offs across configurations: 230 MHz bandwidth at G = +2 (RL = 150 Ω), 90 MHz 0.1 dB flatness bandwidth, and 18 ns settling time to 0.1% - all while sustaining −92 dBc third harmonic distortion at 20 MHz under 2 V_p-p output swing.

FAQ

What supply voltage range does the AD8007AKSZ-REEL7 support?

The AD8007AKSZ-REEL7 operates from a total supply voltage of 5 V to 12 V, supporting both single-supply (e.g., +5 V to ground) and split-supply (e.g., ±5 V) configurations. At ±5 V, it delivers full 650 MHz bandwidth and −83 dBc second harmonic distortion at 20 MHz; at +5 V single supply, bandwidth reduces to 580 MHz but retains 9 mA quiescent current and 0.010° differential phase accuracy - verified per AD8007/AD8008 Rev. E datasheet Table 2.

Is the AD8007AKSZ-REEL7 pin-compatible with other SC70 op amps?

No, the AD8007AKSZ-REEL7 has a unique 5-pin SC70 pinout (VOUT, –IN, +IN, +VS, –VS) not shared by standard SC70 op amps like the ADA4897-1 or OP184. Its current-feedback topology mandates specific feedback resistor placement (typically 499 Ω) and strict decoupling practices - substituting it into existing voltage-feedback layouts without circuit revision will cause instability or degraded distortion performance.

What is the maximum capacitive load the AD8007AKSZ-REEL7 can drive stably?

The AD8007AKSZ-REEL7 is characterized to drive up to 8 pF capacitive load with ≤30% overshoot in unity-gain configuration. Driving larger loads (e.g., >15 pF) requires series output resistance (≥10 Ω) or feedback network adjustment per Figure 47 of the Rev. E datasheet. Uncompensated 50 pF loads induce >20% ringing in large-signal transient response, degrading ADC sampling accuracy.

Does the AD8007AKSZ-REEL7 require external compensation components?

No external compensation is required for unity-gain or inverting configurations. The AD8007AKSZ-REEL7 is internally compensated for stability with standard 499 Ω feedback resistors and 200 Ω source impedances. However, layout-critical decoupling is mandatory: high-frequency 0.1 µF capacitors for +VS and –VS must connect to a single ground point (not separate grounds) to prevent even-order harmonic degradation, as detailed in Figure 53 of the Rev. E datasheet.

How does the AD8007AKSZ-REEL7 perform in NTSC video applications?

The AD8007AKSZ-REEL7 meets broadcast video specifications with 0.010° differential phase error and 0.015% differential gain error at NTSC frequencies (G = +2, RL = 150 Ω), enabling direct replacement of legacy video op amps in RGB or Y/C line drivers. Its 650 MHz bandwidth ensures minimal group delay variation across 4.2 MHz luminance bandwidth, preserving color fidelity without external peaking networks.
