Product details
Overview
AD8007ARZ-R7 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 - enabling precision A/D driver and IF amplifier applications in instrumentation and communications systems.
For engineers reviewing the AD8007ARZ-R7 datasheet, AD8007ARZ-R7 pinout, AD8007ARZ-R7 application, or AD8007ARZ-R7 equivalent, key selection criteria include its 2.7 nV/√Hz input voltage noise, 9 mA quiescent supply current, ±5 V to ±6 V dual-supply operation, and SOIC-8 package compatibility with industrial temperature range (−40°C to +85°C) requirements.
Technical Context
The AD8007ARZ-R7 employs Analog Devices' second-generation XFCB process to achieve current-feedback architecture with low-distortion signal mirrors and active imbalance compensation circuitry. Its high-Z input stage and diamond output topology minimize even-order harmonics through strict top-to-bottom layout symmetry.
It operates as a unity-gain stable current-feedback amplifier with transimpedance gain path, requiring external feedback resistor (typically 499 Ω) and gain-setting resistor. Input common-mode range extends to ±3.9 V on ±5 V supplies, supporting wide dynamic signal handling without rail-to-rail input.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| −3 dB Bandwidth | 650 MHz at G = +1, RL = 1 kΩ - supports wideband baseband and IF signal paths up to UHF |
| Slew Rate | 1000 V/μs - enables clean 2 V step response in ≤2 ns with minimal overshoot |
| Second Harmonic Distortion | −83 dBc @ 20 MHz, 2 V p-p - meets SFDR requirements for 12–14-bit ADC drivers |
| Input Voltage Noise | 2.7 nV/√Hz @ 100 kHz - preserves SNR in low-amplitude, high-gain front-end stages |
| Supply Current | 9 mA per amplifier - allows integration into power-constrained portable or multi-channel systems |
| Input Offset Voltage | 0.5 mV typical - reduces DC error in precision gain blocks and active filter stages |
| Operating Temp Range | −40°C to +85°C - qualified for industrial-grade embedded instrumentation and test equipment |
Pinout & Package
AD8007ARZ-R7 is housed in an 8-lead SOIC (R) package with exposed pad not electrically connected. Pin assignments are validated per Figure 1 of Rev. E datasheet.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No Connect | Internally unconnected; must be left floating or tied to ground per layout best practice |
| 2 | Inverting Input (−IN) | Current-summing node for feedback network; sensitive to parasitic capacitance |
| 3 | Noninverting Input (+IN) | High-impedance emitter-follower input; 1 pF input capacitance limits trace length |
| 4 | No Connect | Internally unconnected; no routing or soldering required |
| 5 | Positive Supply (+VS) | Accepts +5 V to +12 V; requires local 0.1 µF ceramic decoupling to ground |
| 6 | Output (VOUT) | Low-impedance current-source output; drives ≥150 Ω loads directly |
| 7 | No Connect | Internally unconnected; leave unconnected or ground for mechanical stability |
| 8 | Negative Supply (−VS) | Accepts −5 V to −12 V; requires symmetric decoupling to match +VS path |
Key Features
| Feature | Design Value |
|---|---|
| Ultralow distortion architecture | Active input/output voltage imbalance compensation reduces 2nd/3rd harmonic generation by >10 dB vs. legacy CFB amps |
| XFCB process technology | Enables 650 MHz bandwidth with only 9 mA supply current - 72% lower power than comparable GHz-class amplifiers |
| Wide supply range | Operates from ±5 V to ±6 V dual supply or +5 V to +12 V single supply - simplifies system-level power architecture |
| Industrial temperature rating | Guaranteed performance across −40°C to +85°C ambient - suitable for uncooled test equipment and field-deployed sensors |
| SOIC-8 footprint | Drop-in compatible with standard PCB assembly processes and reflow profiles - no redesign needed for legacy layouts |

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 |
|---|---|---|---|
| LMH6629MA/NOPB | Higher 1.5 GHz bandwidth but 15 mA supply current; −76 dBc HD2 @ 20 MHz | Better for >500 MHz RF sampling; less optimal for battery-powered instrumentation | Choose LMH6629 when bandwidth >1 GHz is mandatory and power budget allows +67% current draw |
| ADA4898-1ARZ | Voltage-feedback topology; 280 MHz bandwidth, 1 nV/√Hz noise, −105 dBc HD2 @ 1 MHz | Superior low-frequency distortion and DC precision; unsuitable for >100 MHz IF stages | Choose ADA4898-1 for DC-coupled sensor interfaces or audio-grade reconstruction filters where speed <300 MHz suffices |
Compared with LMH6629MA/NOPB and ADA4898-1ARZ, AD8007ARZ-R7 uniquely balances 650 MHz bandwidth, −83 dBc distortion at 20 MHz, and 9 mA supply current - making it the optimal choice for cost-sensitive, thermally constrained IF and A/D driver applications requiring industrial temperature operation.

FAQ
What is the maximum recommended capacitive load for AD8007ARZ-R7?
The AD8007ARZ-R7 is characterized to drive up to 8 pF capacitive load with ≤30% overshoot under standard test conditions. For loads exceeding 8 pF, a series snub resistor (e.g., 10–20 Ω) between amplifier output and load capacitance is required to maintain stability and preserve transient response integrity. Layout parasitics must be minimized - keep output trace length under 5 mm and avoid vias near the output pin.
Does AD8007ARZ-R7 support single-supply operation?
Yes, AD8007ARZ-R7 supports single-supply operation from +5 V to +12 V. When operated from +5 V, the input common-mode voltage range is 1.1 V to 3.9 V, and output swing is typically 1.05 V to 3.95 V into 1 kΩ. Proper level-shifting of input signals and biasing of feedback network is required to maintain linear operation within these constraints.
What is the purpose of the NC pins on AD8007ARZ-R7?
Pins 1, 4, and 7 of AD8007ARZ-R7 are designated No Connect (NC) and are internally unconnected. They must remain unconnected in the schematic and layout. While grounding them may improve mechanical stability during reflow, doing so does not affect electrical performance and is optional per Analog Devices' design recommendations in the Rev. E datasheet.
How does AD8007ARZ-R7 differ from AD8008 in pinout and functionality?
AD8007ARZ-R7 is a single-channel amplifier in 8-lead SOIC with pins 1, 4, and 7 as NC. AD8008 is a dual-channel version in the same SOIC package but uses all eight pins: pins 1 and 8 are outputs, pins 2/3 and 6/7 are input pairs, and pins 4/5 are supplies. Functionally, AD8008 shares identical per-channel specs but adds −68 dB crosstalk at 5 MHz - AD8007ARZ-R7 has no crosstalk specification as it contains only one amplifier.
Is AD8007ARZ-R7 RoHS compliant and lead-free?
Yes, AD8007ARZ-R7 is RoHS compliant and lead-free. The "RZ" suffix denotes RoHS-compliant, lead-free, 8-lead SOIC packaging per Analog Devices' ordering guide (Rev. E, Page 19). It meets JEDEC J-STD-020 moisture sensitivity level 3 and is qualified for standard SnPb and Pb-free reflow profiles.
