Product details
Overview
AD8007AKS-REEL from Analog Devices is a single-channel, current-feedback operational amplifier optimized for ultralow distortion in high-speed signal conditioning. It delivers 650 MHz −3 dB bandwidth (G = +1), 1000 V/μs slew rate, and −83 dBc second harmonic distortion at 20 MHz, making it suitable for IF/baseband amplification in communications receivers and high-fidelity data acquisition systems.
For engineers reviewing the AD8007AKS-REEL datasheet, AD8007AKS-REEL pinout, AD8007AKS-REEL application, or AD8007AKS-REEL equivalent, key selection criteria include its SC70-5 package footprint, ±5 V to +5 V single-supply compatibility, 2.7 nV/√Hz input voltage noise, and verified performance driving 150 Ω loads at 2 Vp-p with <18 ns 0.1% settling time.
Technical Context
The AD8007AKS-REEL implements a modified current-feedback architecture with low-distortion signal mirrors (M1/M2) and active imbalance compensation (IDI/IDO currents) to suppress even-order harmonics. Its eXtra-Fast Complementary Bipolar (XFCB) process enables simultaneous high bandwidth and low quiescent current (9 mA).
Unlike voltage-feedback op amps, it uses a high-impedance inverting input and low-impedance output, requiring fixed feedback resistor values (e.g., 499 Ω) for stable gain configuration. Input common-mode range extends to ±3.9 V with ±5 V supplies, supporting rail-to-rail output swing into 1 kΩ but limited to ~±3.8 V into 150 Ω.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| −3 dB Bandwidth | 650 MHz at G = +1, RL = 1 kΩ - supports wideband IF stages up to UHF without gain peaking |
| Slew Rate | 1000 V/μs - enables clean 20 MHz sine wave reproduction at 2 Vp-p without slewing-induced distortion |
| Second Harmonic Distortion | −83 dBc @ 20 MHz, 2 Vp-p, RL = 150 Ω - meets stringent SFDR requirements in LTE/WiMAX receiver chains |
| Input Voltage Noise | 2.7 nV/√Hz @ 100 kHz - preserves SNR in low-level signal amplification ahead of ADCs |
| Quiescent Current | 9 mA per amplifier - enables dual-channel designs with <20 mA total supply draw |
| Supply Range | 5 V to 12 V (±2.5 V to ±6 V) - supports both single- and dual-supply operation in portable and industrial systems |
| Settling Time (0.1%) | 18 ns @ G = +2, 2 V step - ensures accurate pulse fidelity in high-speed DAC buffer applications |
Pinout & Package
The AD8007AKS-REEL is housed in a 5-lead SC70 package (JEDEC MO-203AA), measuring 2.0 mm × 2.1 mm × 0.9 mm, with exposed pad for thermal enhancement and space-constrained PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VOUT | Amplifier output | Low-impedance node capable of sourcing 130 mA / sinking 90 mA; requires 0.1 µF decoupling near pin |
| 2 - –IN | Inverting input | High-impedance current-summing node; sensitive to parasitic capacitance - layout must minimize trace length |
| 3 - +IN | Noninverting input | Emitter-follower input with 4 MΩ resistance and 1 pF capacitance; sets common-mode range limits |
| 4 - +VS | Positive supply | Accepts 2.5 V to 6 V; requires dedicated 0.1 µF ceramic capacitor tied to ground plane at package edge |
| 5 - –VS | Negative supply | Ground reference in single-supply mode; must be decoupled identically to +VS for PSRR >59 dB |
Key Features
| Feature | Design Value |
|---|---|
| Ultralow harmonic distortion | −83 dBc HD2 and −92 dBc HD3 @ 20 MHz enable >77 dB SFDR in 14-bit ADC front ends |
| Current-feedback topology | Fixed 499 Ω feedback resistor yields stable G = +2 gain without bandwidth trade-off vs. voltage-feedback parts |
| Asymmetric current mirror compensation | IDO/IDI injection reduces output/input stage voltage imbalances, cutting even-order harmonics by >15 dB vs. legacy CFB amps |
| SC70-5 thermal design | 210°C/W junction-to-ambient (θJA) on 4-layer board allows 150°C max junction temp at 9 mA quiescent load |
| Wide supply flexibility | Operates from +5 V single supply or ±5 V dual supply - simplifies power tree in mixed-signal systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed, low-distortion amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADA4897-1ARJZ-R7 | Lower noise (1 nV/√Hz), lower distortion (−92 dBc HD2 @ 10 MHz), but 220 MHz bandwidth and 10.5 mA IQ | Better for DC-coupled precision gain stages; insufficient bandwidth for >50 MHz IF signals | Select when ultra-low noise dominates over bandwidth; avoid for >30 MHz signal paths |
| LMH6629MA/NOPB | Higher slew rate (1800 V/μs), wider bandwidth (1.5 GHz), but higher distortion (−68 dBc HD2 @ 20 MHz) and 15 mA IQ | Preferred for video line drivers and pulse amplification where speed outweighs linearity | Select when transient response is critical and SFDR >70 dB is acceptable |
Compared with ADA4897-1ARJZ-R7 and LMH6629MA/NOPB, the AD8007AKS-REEL uniquely balances 650 MHz bandwidth, −83 dBc distortion at 20 MHz, and 9 mA quiescent current in a 2.0 × 2.1 mm SC70 package-making it optimal for space-constrained, battery-aware RF receiver IF chains requiring >77 dB SFDR.

FAQ
What is the recommended feedback resistor value for AD8007AKS-REEL in G = +2 configuration?
The AD8007AKS-REEL datasheet specifies 499 Ω as the standard feedback resistor (RF) for G = +2 operation with 200 Ω source resistance (RS). This value ensures stability, flat frequency response up to 230 MHz, and minimal gain error. Deviating from 499 Ω requires re-evaluation of bandwidth, phase margin, and distortion performance per Figure 11 in the AD8007/AD8008 Rev. E datasheet.
Can AD8007AKS-REEL operate from a single +5 V supply?
Yes, AD8007AKS-REEL supports single +5 V operation with input common-mode range of 1.1 V to 3.9 V and output swing of ~0.9 V to 4.1 V into 1 kΩ. For optimal linearity, bias the noninverting input at midsupply (2.5 V) using matched resistors, and ensure load is referenced to ground-not to +5 V-to avoid violating output saturation limits.
What is the maximum capacitive load the AD8007AKS-REEL can drive without instability?
The AD8007AKS-REEL is characterized to drive up to 8 pF capacitive load with ≤30% overshoot in large-signal transient response. Driving >8 pF requires external compensation: add a 10 Ω series snub resistor between output and load (Figure 47), or reduce feedback resistor value to 324 Ω to improve phase margin at the cost of gain accuracy.
How does the SC70-5 package of AD8007AKS-REEL affect thermal performance?
The AD8007AKS-REEL in SC70-5 has a junction-to-ambient thermal resistance (θJA) of 210°C/W on a JEDEC 4-layer board. At 9 mA quiescent current and ±5 V supplies, power dissipation is ~90 mW, resulting in ~19°C junction rise above ambient. To maintain reliability below 150°C junction temperature, ambient must stay below +130°C - though industrial rating limits operation to −40°C to +85°C ambient.
Is AD8007AKS-REEL pin-compatible with other SC70 op amps like AD8065ARTZ-R2?
No, AD8007AKS-REEL is not pin-compatible with AD8065ARTZ-R2 or other SC70 op amps. Its 5-pin SC70 pinout (VOUT, –IN, +IN, +VS, –VS) differs from standard 5-pin voltage-feedback op amp layouts (e.g., +IN, –IN, VOUT, –VS, +VS). Substituting without PCB revision will cause incorrect biasing and functional failure.
