Product details
Overview
AD8039ARZ-REEL from Analog Devices is a dual, low-power, voltage-feedback operational amplifier optimized for high-speed signal conditioning in space- and power-constrained systems. It delivers 350 MHz −3 dB bandwidth (G = +1), 425 V/μs slew rate, and 8 nV/√Hz input voltage noise at 100 kHz, enabling precise buffering and driving of ADCs and video signals in battery-powered instrumentation and portable test equipment.
For engineers reviewing the AD8039ARZ-REEL datasheet, AD8039ARZ-REEL pinout, AD8039ARZ-REEL application, or AD8039ARZ-REEL equivalent, key selection considerations include its dual-channel SOT-23-8 package, 1.0 mA per amplifier quiescent current, rail-to-rail output swing within 1 V of supply rails, and verified performance driving capacitive loads up to 20 pF with minimal peaking.
Technical Context
The AD8039ARZ-REEL implements a voltage-feedback architecture with fully differential input stage and complementary bipolar (XFCB) process technology, enabling simultaneous high speed and ultra-low power operation. Its input common-mode range extends 1 V beyond either rail, and output swings to within 1 V of both supply rails under 2 kΩ load.
Designed for unity-gain stability, it supports gain configurations from +1 to +10 with bandwidth scaling inversely with noise gain. The dual-channel layout minimizes crosstalk (−70 dB at 5 MHz), and each amplifier operates independently across a 3 V to 12 V single- or split-supply range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| −3 dB Bandwidth | 350 MHz at G = +1 (±5 V, 0.5 V p-p); enables full-spectrum fidelity for video and IF signals up to 175 MHz at G = +2. |
| Slew Rate | 425 V/μs (±5 V, 2 V step); supports clean 100+ MSPS transient response without slewing distortion. |
| Input Voltage Noise | 8 nV/√Hz @ 100 kHz; preserves SNR in precision signal chains where source impedance is <1 kΩ. |
| Quiescent Current | 1.0 mA per amplifier (typical); allows dual-channel amplification in sub-2 mA total system budget. |
| Capacitive Load Drive | 20 pF (30% overshoot, G = +2); eliminates need for external isolation resistors in most ADC driver layouts. |
| Input Common-Mode Range | ±4 V (RL = 1 kΩ, ±5 V supply); accommodates wide-range sensor outputs and level-shifted interfaces. |
| Output Voltage Swing | ±4 V (RL = 2 kΩ, ±5 V); delivers >80% of rail-to-rail dynamic range for maximum ADC utilization. |
Pinout & Package
AD8039ARZ-REEL is housed in an 8-lead SOT-23 package (JEDEC MO-178AA), measuring 2.9 mm × 1.6 mm × 1.1 mm, with gull-wing leads and exposed pad not electrically connected. Pin 1 is marked by a dot; pin numbering follows standard SOT-23 counterclockwise from the mark.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VOUT1 | Channel 1 output | Low-impedance buffered output capable of driving 2 kΩ loads to ±4 V with <18 ns 0.1% settling. |
| –IN1 | Channel 1 inverting input | Differential input node; 10 MΩ input resistance and 2 pF capacitance require tight layout to avoid peaking. |
| +IN1 | Channel 1 noninverting input | High-impedance input referenced to system ground or bias network; supports dc-coupled sensor interfacing. |
| –VS | Negative supply rail | Accepts −1.5 V to −6 V in split-supply mode or serves as ground reference in single-supply configuration. |
| +VS | Positive supply rail | Accepts +3 V to +12 V; PSRR >64 dB ensures immunity to supply ripple in noisy environments. |
| VOUT2 | Channel 2 output | Independent output with matched AC performance; crosstalk −70 dB at 5 MHz prevents inter-channel interference. |
| –IN2 | Channel 2 inverting input | Electrically isolated from Channel 1 inputs; enables dual-path signal processing without shared-node coupling. |
| +IN2 | Channel 2 noninverting input | Identical electrical characteristics to +IN1; supports parallel channel configuration for differential signaling. |
Key Features
| Feature | Design Value |
|---|---|
| Low-power operation | 1.0 mA per amplifier enables dual-channel analog front-end design within 2.5 mA total supply budget. |
| High-speed voltage feedback | 350 MHz bandwidth and 425 V/μs slew rate support accurate reproduction of fast edges in video and data acquisition. |
| Low-noise signal conditioning | 8 nV/√Hz voltage noise and 600 fA/√Hz current noise preserve dynamic range when interfacing high-Z sensors. |
| Rail-compatible I/O | Input common-mode range extends 1 V beyond rails; output swings to within 1 V of rails-ideal for 3.3 V and 5 V systems. |
| Capacitive load tolerance | Stable drive of up to 20 pF without external compensation simplifies ADC interface layout and reduces BOM count. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual high-speed op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMH6629MA/NOPB | Higher power (4.5 mA/amp), higher bandwidth (1.5 GHz), no disable feature; SOIC-8 only. | Better for RF IF stages requiring >1 GHz small-signal BW; unsuitable for sub-3 mA battery designs. | Select LMH6629MA/NOPB only when bandwidth >1 GHz and power budget >9 mA is available. |
| ADA4891-2ARZ | Lower bandwidth (225 MHz), lower noise (4 nV/√Hz), same 1.2 mA/amp quiescent current; SOIC-8/SOT-23-8. | Better for precision low-frequency sensor signal chains; insufficient for >150 MHz video or ADC sampling. | Choose ADA4891-2ARZ when noise <5 nV/√Hz is critical and bandwidth ≤200 MHz suffices. |
Compared with LMH6629MA/NOPB and ADA4891-2ARZ, AD8039ARZ-REEL uniquely balances 350 MHz bandwidth, 1.0 mA/amp quiescent current, and SOT-23-8 footprint-making it the only dual op amp meeting both high-speed and ultra-low-power requirements in compact portable systems.

FAQ
What is the operating temperature range for the AD8039ARZ-REEL?
The AD8039ARZ-REEL is rated for continuous operation from −40°C to +85°C, meeting industrial-grade environmental requirements. This range is validated across all key specifications including bandwidth, slew rate, and input offset voltage, ensuring reliable performance in outdoor instrumentation, factory automation, and automotive cabin electronics where thermal cycling occurs.
Does the AD8039ARZ-REEL support single-supply operation?
Yes, the AD8039ARZ-REEL supports true single-supply operation from +3 V to +12 V. With input common-mode range extending down to 1.0 V above negative rail (ground in single-supply mode) and output swing to within 1 V of both rails, it enables rail-to-rail signal handling in 3.3 V and 5 V systems without level-shifting circuitry.
What is the maximum capacitive load the AD8039ARZ-REEL can drive without instability?
The AD8039ARZ-REEL is characterized to drive up to 20 pF capacitive loads with ≤30% overshoot at G = +2. For loads exceeding 20 pF, a series resistor (e.g., 10–22 Ω) placed directly at the output pin restores stability-verified in Figure 27 and Figure 28 of the Rev. G datasheet.
Is the AD8039ARZ-REEL pin-compatible with other dual op amps in SOT-23-8 packages?
No, the AD8039ARZ-REEL uses a proprietary pinout (VOUT1, –IN1, +IN1, –VS, +VS, VOUT2, –IN2, +IN2) that differs from industry-standard dual op amp SOT-23-8 layouts such as the LMV791 or ADA4891-2. PCB redesign is required for substitution; always verify pin mapping before layout reuse.
How does the AD8039ARZ-REEL achieve low distortion at high frequencies?
The AD8039ARZ-REEL achieves −90 dB SFDR at 1 MHz and −65 dB SFDR at 5 MHz through XFCB process optimization, symmetric internal transistor sizing, and careful compensation design. Its dual-channel architecture maintains inter-channel phase matching to minimize even-order harmonic generation in differential configurations.
