Product details
Overview
AD8066AR-REEL7 from Analog Devices is a dual, high-speed, FET-input operational amplifier optimized for precision signal conditioning in demanding analog front-ends. 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 1 pA typical input bias current - enabling high-fidelity photodiode preamplification and A/D driver applications.
For engineers reviewing the AD8066AR-REEL7 datasheet, AD8066AR-REEL7 pinout, AD8066AR-REEL7 application, or AD8066AR-REEL7 equivalent, key selection criteria include its dual-channel SOIC-8 configuration, ±5 V to ±12 V supply flexibility, −100 dB CMRR, 0.02% differential gain error for video, and verified performance across −40°C to +85°C industrial temperature range.
Technical Context
The AD8066AR-REEL7 employs a voltage-feedback architecture with JFET input stage, delivering ultra-low input bias current and high input impedance (1000 GΩ || 4.5 pF differential). Its XFCB process enables simultaneous high speed and low noise - critical for wideband photodiode preamps and high-resolution data acquisition where leakage and thermal drift must be minimized.
It supports single-supply operation down to +5 V with rail-to-rail output, maintains 0.1 dB flatness to 7 MHz at G = +2, and exhibits no phase reversal under overdrive. The dual amplifier topology allows matched channel performance in instrumentation-grade filtering and level-shifting circuits without inter-channel crosstalk degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| −3 dB Bandwidth | 145 MHz at G = +1 (±5 V); enables baseband video and fast pulse amplification without roll-off |
| Slew Rate | 180 V/µs at G = +2 (±5 V); supports clean 10 V step response in <205 ns for high-speed DAC buffering |
| Input Bias Current | 1 pA typical (SOIC-8); preserves signal integrity in high-impedance sensor interfaces like photodiodes |
| Input Voltage Noise | 7 nV/√Hz at 10 kHz; minimizes added noise in low-level signal amplification paths |
| CMRR | −100 dB (VCM = −1 V to +1 V); rejects common-mode interference in noisy industrial environments |
| Supply Range | ±5 V to ±12 V (or +5 V to +24 V); accommodates legacy bipolar rails and modern single-supply systems |
| Quiescent Current | 6.4 mA per amplifier (±5 V); balances speed and power efficiency in multi-channel designs |
Pinout & Package
AD8066AR-REEL7 is housed in an 8-lead SOIC package (SOIC-8, body width 3.9 mm) with standard JEDEC MS-012AC footprint. Pin 1 is marked by a dot or notch; device orientation follows industry-standard top-view labeling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Amplifier 1) | High-impedance FET node; connects to feedback network for precise gain setting |
| 2 | Noninverting Input (Amplifier 1) | High-Z input for reference or sensor signal; common-mode range extends to −5 V (±5 V supply) |
| 3 | Output (Amplifier 1) | Rail-to-rail capable; drives 1 kΩ load to ±4.9 V with <0.1% settling in 55 ns |
| 4 | Negative Supply (−VS) | Reference for both amplifiers; must be bypassed locally with ≥0.1 µF ceramic capacitor |
| 5 | Positive Supply (+VS) | Power rail for both amplifiers; decoupling required within 5 mm of pin for stability |
| 6 | Noninverting Input (Amplifier 2) | Independent high-Z input; matches Amp1 specs for dual-channel synchronous signal processing |
| 7 | Inverting Input (Amplifier 2) | Matched to Pin 1; supports identical feedback configurations as Amp1 |
| 8 | Output (Amplifier 2) | Identical AC/DC performance to Pin 3; enables compact dual-path signal chains |

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 |
|---|---|---|---|
| OPA2691IDR | Higher 320 MHz bandwidth but 2.5 pA input bias current; 11.5 mA quiescent current per amp | Better for RF IF amplification; less suitable for ultra-high-Z photodiode nodes | Choose OPA2691IDR when bandwidth >200 MHz is mandatory and input leakage tolerance >2 pA exists |
| LMH6629MA/NOPB | Lower 1.2 nV/√Hz noise but 100 kHz GBW; 10 mA quiescent current; not rail-to-rail output | Optimized for low-noise audio and precision DC; lacks video flatness and fast settling | Choose LMH6629MA/NOPB only for sub-MHz, ultra-low-noise DC-coupled applications requiring <2 nV/√Hz |
Compared with AD8066AR-REEL7, OPA2691IDR trades higher speed for increased input leakage and power, while LMH6629MA/NOPB sacrifices bandwidth and rail-to-rail capability for lower voltage noise - making AD8066AR-REEL7 the balanced choice for dual-channel, wideband, low-leakage signal conditioning.

FAQ
What is the maximum operating temperature range for AD8066AR-REEL7?
The AD8066AR-REEL7 is rated for continuous operation from −40°C to +85°C, with all electrical specifications guaranteed across this industrial temperature range. It is not qualified for automotive extended temperature (−40°C to +105°C); that rating applies only to the AD8065WARTZ-R7 variant. Thermal derating above 85°C is not supported per datasheet limits.
Does AD8066AR-REEL7 support single-supply operation?
Yes, AD8066AR-REEL7 supports true single-supply operation from +5 V to +24 V. Its rail-to-rail output swings within 100 mV of both supply rails (e.g., 0.03 V to 4.95 V on +5 V), and the input common-mode range extends to 0 V (with 0.17 V headroom to positive rail). Input bias current remains stable across the full supply range.
What is the typical input bias current of AD8066AR-REEL7 at 25°C?
The typical input bias current of AD8066AR-REEL7 is 1 pA at 25°C (SOIC-8 package), with a maximum of 6 pA. This value increases to ≤125 pA over the full −40°C to +85°C operating range. The ultra-low bias enables use with high-impedance sources such as photodiodes, piezoelectric sensors, and pH electrodes without significant offset error.
Can AD8066AR-REEL7 drive capacitive loads?
AD8066AR-REEL7 can drive up to 5 pF with 30% overshoot at G = +1 under +5 V supply, and up to 25 pF under ±12 V supply. For larger capacitive loads (e.g., ADC input capacitance), external series resistance (≥20 Ω) is recommended at the output to maintain stability. Layout best practices - including short traces and local bypassing - are essential for reliable high-frequency performance.
Is AD8066AR-REEL7 pin-compatible with other dual op amps in SOIC-8?
No, AD8066AR-REEL7 has a nonstandard pinout optimized for dual-channel symmetry: Pins 1/2/3 and 6/7/8 form two independent amplifier sections sharing common supplies (Pins 4/5). It is not pin-compatible with generic dual op amps like LM358 or TL072. Refer to Figure 1 in the AD8065/AD8066 datasheet Rev. L for exact terminal mapping before PCB layout.
