Product details
Overview
AD8040ARZ from Analog Devices is a quad, rail-to-rail input/output high-speed voltage feedback amplifier optimized for low-power, wideband signal conditioning in single-supply systems. It delivers 125 MHz –3 dB bandwidth (G = +1), 60 V/µs slew rate, and 80 ns settling time to 0.1%, operating from 2.7 V to 12 V supply with quiescent current of 1.3 mA per amplifier. It is used in A-to-D drivers, active filters, and buffering stages in automotive vision systems and portable instrumentation.
For engineers reviewing the AD8040ARZ datasheet, AD8040ARZ pinout, AD8040ARZ application, or AD8040ARZ equivalent, key selection criteria include its rail-to-rail I/O swing within 40 mV of rails, crosstalk of –79 dB at 5 MHz, and guaranteed operation across –40°C to +125°C - critical for battery-powered, space-constrained, and automotive-grade designs requiring stable AC performance and low distortion.
Technical Context
The AD8040ARZ employs Analog Devices' proprietary XFCB process to achieve high-speed operation with low power consumption. Its input stage supports true rail-to-rail common-mode range extending 200 mV beyond either supply rail without phase reversal, while the output stage drives to within 40 mV of each rail under 1 kΩ load.
As a quad amplifier, it integrates four independent channels in one SOIC-14 package, sharing no internal bias or reference coupling - confirmed by crosstalk of –79 dB at 5 MHz. Each channel features disable control (via dedicated pin on AD8029 only; not present on AD8040), and all channels are fully specified for ±5 V, +5 V, and +3 V supplies with consistent dynamic performance metrics.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| –3 dB Bandwidth | 125 MHz at G = +1, VO = 0.1 V p-p - enables baseband signal amplification up to ~125 MHz without significant attenuation. |
| Slew Rate | 60 V/µs - supports fast transient response for high-slew signals like video or pulse waveforms without distortion. |
| Settling Time to 0.1% | 80 ns at G = +2, VO = 2 V step - ensures accurate sampling in ADC driver applications with minimal acquisition delay. |
| Input Offset Voltage | Max 6 mV - limits DC error in precision gain stages and sensor signal chains. |
| Supply Range | 2.7 V to 12 V - allows direct integration into 3.3 V, 5 V, and dual ±5 V systems without level-shifting. |
| Quiescent Current | 1.3 mA per amplifier - enables four-channel amplification at just 5.2 mA total, ideal for battery-operated equipment. |
| Crosstalk | –79 dB at 5 MHz - confirms channel isolation sufficient for multi-channel data acquisition without inter-channel interference. |
Pinout & Package
AD8040ARZ is packaged in a 14-lead SOIC (Small Outline Integrated Circuit) with standard pin spacing and thermal characteristics suitable for industrial and automotive PCB layouts. The package is RoHS-compliant and rated for operation from –40°C to +125°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 8, 12 | VOUT | Amplifier output terminals for Channels 1–4 respectively; rail-to-rail swing supports full-scale signal delivery to ADC inputs or downstream stages. |
| 2, 6, 9, 13 | –IN | Inverting inputs for Channels 1–4; high impedance (6 MΩ) minimizes loading on preceding stages. |
| 3, 7, 10, 14 | +IN | Non-inverting inputs for Channels 1–4; supports rail-to-rail common-mode input range (–0.2 V to +5.2 V at +5 V supply). |
| 4 | –VS | Negative supply rail connection; required even in single-supply operation where –VS = ground. |
| 11 | +VS | Positive supply rail connection; accepts 2.7 V to 12 V, enabling flexible system-level power architecture. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Input common-mode range extends 200 mV beyond rails; output swings to within 40 mV of rails - maximizes dynamic range in low-voltage systems. |
| No phase reversal | Inputs tolerate overvoltage up to ±200 mV beyond supply rails without output polarity inversion - improves robustness in transient-prone environments. |
| Low distortion | SFDR = –72 dBc at 1 MHz (2 V p-p) - preserves signal fidelity in high-resolution ADC driver and communication front-end applications. |
| Wide temperature range | Specified from –40°C to +125°C - qualified for under-hood automotive and industrial control applications. |
| Low input bias current | +0.7 µA to –1.5 µA - reduces voltage error in high-impedance sensor interfaces and filter networks. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed, low-power operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMH6612MMX/NOPB | Lower bandwidth (80 MHz), higher quiescent current (2.3 mA/channel), no guaranteed –40°C to +125°C operation. | Not qualified for automotive; less suitable for extended-temperature industrial use. | Prefer AD8040ARZ when wide temperature range, lower power, or higher bandwidth is required. |
| ADA4891-4ARUZ | Higher quiescent current (6.5 mA/channel), wider supply range (2.7 V to 12 V), but lower slew rate (225 V/µs) and bandwidth (225 MHz). | Better for ultra-high-speed applications but consumes >5× more power per channel. | Choose AD8040ARZ for optimal balance of speed, power, and temperature range in cost- and power-sensitive designs. |
Compared with LMH6612MMX/NOPB and ADA4891-4ARUZ, AD8040ARZ offers superior power efficiency (1.3 mA/channel) and guaranteed automotive-grade temperature operation (–40°C to +125°C), making it the preferred choice for battery-powered and safety-critical signal conditioning where thermal stability and low standby dissipation are essential.

FAQ
What is the operating temperature range for AD8040ARZ?
The AD8040ARZ is rated for operation from –40°C to +125°C, meeting extended industrial and automotive qualification requirements. This specification is guaranteed across all electrical parameters in the datasheet, including bandwidth, slew rate, and offset voltage, making AD8040ARZ suitable for under-hood automotive electronics and harsh-environment industrial controls.
Does AD8040ARZ include a disable function?
No, AD8040ARZ does not feature a disable pin. The disable function is only implemented on the single-channel AD8029 variant. AD8040ARZ provides four fully independent amplifier channels without enable/disable control; power-down must be managed externally via supply sequencing or external switches if required.
What package type is used for AD8040ARZ?
AD8040ARZ is supplied in a 14-lead SOIC (Small Outline Integrated Circuit) package, designated as "R" in Analog Devices' ordering guide. It has standard 1.27 mm lead pitch, gull-wing leads, and is RoHS-compliant. The package is compatible with automated SMT assembly and supports JEDEC-standard thermal profiles.
Can AD8040ARZ operate from a single 3.3 V supply?
Yes, AD8040ARZ operates from a single 3.3 V supply (within its 2.7 V to 12 V range). At +3.3 V, it maintains 112 MHz –3 dB bandwidth (G = +1), 55 V/µs slew rate, and rail-to-rail input/output swing - delivering full functionality in modern low-voltage digital systems without level translation.
How does AD8040ARZ compare to AD8040W?
AD8040W is the automotive-qualified version of AD8040, tested and certified to AEC-Q100 Grade 2 (–40°C to +105°C ambient) with enhanced reliability screening. AD8040ARZ is the commercial/industrial variant, rated –40°C to +125°C junction but not AEC-Q100 certified. Both share identical pinout, electrical specs, and SOIC-14 packaging; AD8040ARZ is appropriate for non-automotive industrial applications requiring extended temperature capability.
