Product details
Overview
AD8066ARMZ-REEL7 from Analog Devices is a dual, high-speed, FET-input operational amplifier optimized for photodiode preamplification, video buffering, and A/D driver applications. It delivers 145 MHz −3 dB bandwidth (G = +1), 180 V/µs slew rate (G = +2), 7 nV/√Hz input voltage noise at 10 kHz, rail-to-rail output swing, and operates from ±5 V to ±12 V or single +5 V supplies.
For engineers reviewing the AD8066ARMZ-REEL7 datasheet, AD8066ARMZ-REEL7 pinout, AD8066ARMZ-REEL7 application, or AD8066ARMZ-REEL7 equivalent, this page provides verified package mapping (MSOP-8), confirmed dual-channel topology, validated pin functions, real-world distortion specs (−88 dBc SFDR @ 1 MHz), and cross-referenced automotive-grade alternatives with documented thermal and supply-range differences.
Technical Context
The AD8066ARMZ-REEL7 implements a voltage-feedback architecture with JFET input stage enabling 1 pA typical input bias current and >1 TΩ differential input impedance. Its XFCB process ensures low 7 nV/√Hz voltage noise and 0.6 fA/√Hz current noise at 10 kHz while maintaining −100 dB CMRR and 113 dB open-loop gain under ±5 V operation.
It supports rail-to-rail output swing into 1 kΩ loads (−4.94 V to +4.95 V), drives ≥35 mA, recovers from overdrive in ≤175 ns, and sustains stable operation with capacitive loads up to 20 pF (G = +1). The device is rated for −40°C to +85°C industrial temperature range and requires no phase reversal protection circuitry.
Key Specifications

| Input Voltage Noise | 7 nV/√Hz at 10 kHz; critical for low-noise photodiode and sensor front-end amplification |
| Input Bias Current | 1 pA typical; preserves high-impedance source integrity in precision transimpedance designs |
| Supply Range | ±5 V to ±12 V or +5 V single supply; accommodates legacy bipolar and modern low-voltage systems |

| Harmonic Distortion | −88 dBc SFDR @ 1 MHz, G = +2, 2 V p-p; meets broadcast video and instrumentation linearity requirements |
Pinout & Package
AD8066ARMZ-REEL7 is housed in an 8-lead MSOP (RM-8) package, 3 mm × 3 mm × 0.85 mm body, exposed pad for thermal enhancement, RoHS-compliant, tape-and-reel packaging (REEL7).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT1) | Amplifier 1 output | Delivers rail-to-rail buffered or amplified signal; capable of sourcing/sinking ≥35 mA |
| 2 (−IN1) | Inverting input, Amp 1 | High-impedance FET node (1000 GΩ || 4.5 pF); used for feedback network connection |
| 3 (+IN1) | Noninverting input, Amp 1 | High-impedance FET node (1000 GΩ || 2.1 pF); accepts DC-coupled or AC-coupled sensor signals |
| 4 (−VS) | Negative supply rail | Reference for internal biasing; must be decoupled with 0.1 µF ceramic near pin |
| 5 (+IN2) | Noninverting input, Amp 2 | Independent high-Z input for second channel; electrically isolated from Amp 1 inputs |
| 6 (−IN2) | Inverting input, Amp 2 | Independent feedback node; supports separate gain configuration per channel |
| 7 (OUT2) | Amplifier 2 output | Second independent rail-to-rail output; shares same supply rails and thermal path as OUT1 |
| 8 (+VS) | Positive supply rail | Power input for both amplifiers; requires local 0.1 µF + 10 µF bypassing for stability |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed FET-input op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADA4897-2ARMZ | Lower 4 nV/√Hz noise, 200 MHz bandwidth, but 2.2 mA lower quiescent current (4.2 mA vs. 6.4 mA) | Better suited for battery-powered portable instrumentation; less drive capability (20 mA vs. 35 mA) | Select ADA4897-2ARMZ when ultra-low noise dominates over output current and cost sensitivity is moderate. |
| LMH6629MA/NOPB | Higher 220 V/µs slew rate, wider 1.5 GHz GBW, but higher 12.5 mA supply current and no rail-to-rail output | Preferred for RF IF amplification and active filter stages requiring >500 MHz closed-loop bandwidth | Select LMH6629MA/NOPB when speed and gain-bandwidth exceed AD8066ARMZ-REEL7 limits, and rail-to-rail output is not required. |
Compared with ADA4897-2ARMZ and LMH6629MA/NOPB, AD8066ARMZ-REEL7 offers optimal balance of noise (7 nV/√Hz), drive strength (35 mA), rail-to-rail output, and industrial temperature rating at lower cost-making it ideal for photodiode preamps, video buffers, and medium-speed ADC drivers where power efficiency and output swing are jointly critical.

FAQ
What is the operating temperature range for AD8066ARMZ-REEL7?
The AD8066ARMZ-REEL7 is rated for industrial operation from −40°C to +85°C. This range is specified in the Absolute Maximum Ratings table and validated across all key parameters including bandwidth, slew rate, and offset voltage. It does not support the extended −40°C to +105°C automotive range-that applies only to the AD8065WARTZ-R7 variant. Thermal derating begins above +85°C ambient per Figure 3 in the datasheet.
Does AD8066ARMZ-REEL7 support single-supply operation?
Yes, AD8066ARMZ-REEL7 supports true single-supply operation down to +5 V. When powered from +5 V, it delivers rail-to-rail output swing (0.03 V to 4.95 V into 1 kΩ), maintains 130–160 V/µs slew rate, and achieves 125–155 MHz −3 dB bandwidth. Input common-mode range extends from 0 V to +2.4 V, allowing direct interfacing with sensors and DACs referenced to ground or mid-supply.
What is the maximum capacitive load AD8066ARMZ-REEL7 can drive stably?
AD8066ARMZ-REEL7 drives up to 20 pF capacitively loaded at G = +1 with ≤30% overshoot, as specified in the ±5 V Electrical Characteristics table. For loads >20 pF, external series resistance (e.g., 10–50 Ω) at the output is recommended to maintain phase margin. Stability with 150 Ω resistive load plus cable capacitance is confirmed in video buffer application circuits (Figure 26 in datasheet).
Is AD8066ARMZ-REEL7 pin-compatible with other op amps in the AD8065/AD8066 family?
Yes-AD8066ARMZ-REEL7 shares identical MSOP-8 pinout with all AD8066 variants (e.g., AD8066ARZ, AD8066ARZ-REEL), including pin-for-pin mapping for both amplifier sections, supply pins, and unused terminals. However, it is not pin-compatible with AD8065 (single-channel) SOIC-8 or SOT-23-5 packages due to differing channel count and footprint.
What PCB layout practices are recommended for AD8066ARMZ-REEL7?
For optimal AD8066ARMZ-REEL7 performance: place 0.1 µF ceramic + 10 µF bulk capacitor within 2 mm of each supply pin; use solid ground plane beneath the MSOP-8; keep input traces short and symmetric; avoid vias in sensitive analog paths; and thermally connect the exposed pad to inner ground plane using ≥4 thermal vias. These practices minimize parasitic inductance/capacitance and ensure stability per Layout, Grounding, and Bypassing Considerations section (page 23).
