Product details
Overview
AD8040WARUZ-REEL7 from Analog Devices is a quad-channel, rail-to-rail input/output high-speed voltage feedback amplifier optimized for automotive safety and vision systems. It delivers 125 MHz –3 dB bandwidth (G = +1), 60 V/µs slew rate, 80 ns settling to 0.1%, and operates from 2.7 V to 12 V supply with only 1.3 mA per amplifier quiescent current. Its ±40 mV output swing margin to rails enables full dynamic range in single-supply A-to-D driver applications.
For engineers reviewing the AD8040WARUZ-REEL7 datasheet, AD8040WARUZ-REEL7 pinout, AD8040WARUZ-REEL7 application, or AD8040WARUZ-REEL7 equivalent, key selection criteria include guaranteed automotive-grade temperature operation (–40°C to +125°C), crosstalk performance (–79 dB at 5 MHz), disable functionality per channel, and SOIC-14 package compatibility with space-constrained PCB layouts.
Technical Context
The AD8040WARUZ-REEL7 implements a proprietary XFCB process enabling high-speed performance at low power. Its input stage supports true rail-to-rail common-mode range extending 200 mV beyond supply rails without phase reversal, while the output stage achieves <40 mV saturation voltage to each rail under 1 kΩ load.
Each of the four amplifiers features independent disable control, allowing dynamic power management. The device maintains stable operation with capacitive loads up to 20 pF and exhibits low distortion (SFDR = –72 dBc at 1 MHz) critical for precision signal conditioning before ADC sampling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| –3 dB Bandwidth | 125 MHz at G = +1, 0.1 Vp-p; ensures fidelity for video and sensor signals up to ~60 MHz Nyquist frequency |
| Slew Rate | 60 V/µs; supports fast transient response for pulse-shaped inputs without slew-induced distortion |
| Settling Time | 80 ns to 0.1%; enables accurate sampling of multi-MHz signals in successive-approximation ADC drivers |
| Supply Range | 2.7 V to 12 V; compatible with automotive battery rails (9–16 V nominal) and low-voltage embedded systems |
| Quiescent Current | 1.3 mA per amplifier; total 5.2 mA for all four channels, minimizing thermal load in sealed enclosures |
| Input Offset Voltage | Max 9.5 mV over –40°C to +125°C; ensures DC accuracy in closed-loop sensor interfaces |
| Crosstalk | –79 dB at 5 MHz; prevents inter-channel interference in multi-signal acquisition (e.g., stereo camera streams) |
Pinout & Package
AD8040WARUZ-REEL7 is housed in a 14-lead SOIC (SOIC-14, RU package) with exposed pad for thermal enhancement. Pin 1 is marked by a notch or dot; pin numbering follows standard SOIC convention (counterclockwise from top-left corner).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 6 | +VS | Positive supply rail; decoupling capacitor required within 1 cm for stability |
| 7 | –IN 2 | Inverting input for Amp 2; layout symmetry recommended vs. Amp 1 for matching |
| 8 | +IN 2 | Non-inverting input for Amp 2; shares same input capacitance (2 pF) as other channels |
| 9 | VOUT 3 | Amplifier 3 output; supports independent gain configuration per channel |
| 10 | –IN 3 | Inverting input for Amp 3; referenced to same –VS as all channels |
| 11 | +IN 3 | Non-inverting input for Amp 3; immune to phase reversal up to 200 mV beyond rails |

| 13 | –IN 4 | Inverting input for Amp 4; matches input bias current (±0.9 µA max) across temperature |
| 14 | +IN 4 | Non-inverting input for Amp 4; supports common-mode range from –0.2 V to +5.2 V @ +5 V supply |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Input extends 200 mV beyond rails; output swings within 40 mV of rails - maximizes dynamic range in 3.3 V or 5 V systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADA4891-4ARUZ | Lower bandwidth (220 MHz), higher quiescent current (6.5 mA/ch), no disable pin, same SOIC-14 package | Preferred for non-automotive, higher-speed designs where power budget allows | Select ADA4891-4ARUZ when >150 MHz bandwidth is required and automotive qualification is unnecessary |
| LMH6612MMX/NOPB | Higher supply current (2.3 mA/ch), wider supply range (2.7–12.6 V), no automotive grade, MSOP-8 package (dual only) | Suitable for dual-channel industrial instrumentation where board space is constrained | Choose LMH6612MMX/NOPB for cost-sensitive dual-amplifier applications without temperature or disable requirements |
Compared with ADA4891-4ARUZ and LMH6612MMX/NOPB, AD8040WARUZ-REEL7 uniquely combines automotive qualification, per-channel disable, and 1.3 mA/ch power consumption in a quad SOIC-14 - making it optimal for thermally limited ADAS modules requiring functional safety compliance.

FAQ
What is the operating temperature range for AD8040WARUZ-REEL7?
The AD8040WARUZ-REEL7 is qualified for automotive applications and operates across –40°C to +125°C. This Grade 1 specification is explicitly confirmed in the datasheet's revision history and automotive model section, ensuring reliability in engine bay and ADAS camera environments where ambient temperatures exceed 100°C.
Does AD8040WARUZ-REEL7 support single-supply operation?
Yes, AD8040WARUZ-REEL7 supports true single-supply operation from 2.7 V to 12 V. Its rail-to-rail input extends 200 mV beyond the negative rail (e.g., ground), and its output swings within 40 mV of both rails - enabling direct interface with 3.3 V or 5 V ADCs without level-shifting components.
How many amplifiers does AD8040WARUZ-REEL7 contain, and are they independent?
AD8040WARUZ-REEL7 contains four fully independent operational amplifiers in one SOIC-14 package. Each amplifier has dedicated input and output pins, and the datasheet confirms crosstalk of –79 dB at 5 MHz - verifying electrical isolation sufficient for multi-channel signal paths like stereo vision or multi-phase motor sensing.
Is there a disable function on AD8040WARUZ-REEL7, and how is it implemented?
Unlike the single-channel AD8029, the AD8040WARUZ-REEL7 does not include a dedicated disable pin per amplifier. The datasheet specifies disable functionality only for AD8029 (Figure 1). For AD8040, power management must be achieved via global supply control or external switching - confirmed by absence of DISABLE pin in SOIC-14 connection diagram (Figure 4).
What package type is used for AD8040WARUZ-REEL7, and what does the "RU" suffix indicate?
AD8040WARUZ-REEL7 uses the SOIC-14 package, designated "RU" in Analog Devices' ordering guide. The "RU" suffix corresponds to the 14-lead narrow-body SOIC outline with 1.27 mm lead pitch and specified thermal characteristics (θJA = 90°C/W on JEDEC 4-layer board), as documented in the Outline Dimensions section of the datasheet.
