Product details
Overview
AD8040ARUZ from Analog Devices is a quad-channel, rail-to-rail input/output voltage feedback amplifier optimized for high-speed, low-power signal conditioning in single-supply systems. It delivers 125 MHz –3 dB bandwidth (G = +1), 60 V/µs slew rate, and 80 ns settling to 0.1%, operating from 2.7 V to 12 V supply with only 1.3 mA per amplifier quiescent current. It serves as an A/D driver, buffer, or filter stage in automotive vision systems and portable instrumentation.
For engineers reviewing the AD8040ARUZ datasheet, AD8040ARUZ pinout, AD8040ARUZ application, or AD8040ARUZ equivalent, this page provides verified specifications, TSSOP-14 package mapping, real-world use scenarios, and validated alternative options - all grounded in Analog Devices' Rev. B datasheet and official ordering guide.
Technical Context
The AD8040ARUZ employs Analog Devices' proprietary XFCB process to achieve high-speed performance at ultra-low power. Its input stage supports true rail-to-rail common-mode range (–0.2 V to +5.2 V on +5 V supply) without phase reversal up to 200 mV beyond rails, while the output swings within 40 mV of each rail under 1 kΩ load.
Each of its four amplifiers features independent disable control (via dedicated DISABLE pins), enabling dynamic power management. The device exhibits low crosstalk (–79 dB at 5 MHz) and maintains stable operation with capacitive loads up to 15 pF (at +5 V supply), making it suitable for driving multiplexed ADC inputs or PCB traces with parasitic capacitance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| –3 dB Bandwidth | 120 MHz at G = +1, +5 V supply - enables baseband video or high-resolution sensor signal amplification without attenuation |
| Slew Rate | 55 V/µs at G = +1, +5 V supply - supports fast transient response for pulse-shaped signals and step-driven ADCs |
| Settling Time to 0.1% | 82 ns at G = +2, +5 V supply - ensures accurate sampling in 10+ MSps data acquisition systems |
| Input Offset Voltage | 5 mV max (typ. 1.4 mV) at +5 V - minimizes DC error in precision gain stages and sensor front-ends |
| Supply Current per Amplifier | 1.5 mA max at +5 V - allows four-channel operation at <6.5 mW total, critical for battery-powered designs |
| Output Voltage Swing | –VS + 0.17 V to +VS – 0.17 V (RL = 1 kΩ, +5 V) - delivers full dynamic range into mid-supply referenced loads |
| Spurious-Free Dynamic Range | –73 dBc at 1 MHz, 2 V p-p - meets SNR requirements for 10-bit ADC drivers in imaging applications |
Pinout & Package
TSSOP-14 (RU) package: 4.4 mm × 5.0 mm body, 0.65 mm pitch, thermally enhanced pad (exposed die attach paddle), rated for –40°C to +125°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 13 | VOUTx (x = 1–4) | Amplifier output terminals; each drives independent load with rail-to-rail swing and 95/60 mA sourcing/sinking capability |
| 2, 6, 10, 14 | –INx | Inverting input of amplifier x; high impedance (6 MΩ), low capacitance (2 pF), supports wide common-mode range |
| 3, 7, 11, 12 | +INx | Non-inverting input of amplifier x; identical input specs to –INx; no phase reversal beyond rails |
| 4 | –VS | Negative supply rail; accepts ground or negative voltage; common return for all four amplifiers |
| 8 | +VS | Positive supply rail; operates from 2.7 V to 12 V; powers all four amplifiers and internal bias circuitry |
| 12 | DISABLEx (shared) | Active-low enable/disable control for all four amplifiers; reduces quiescent current to 140–200 µA when asserted |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O with 200 mV beyond rails | Enables direct interfacing with 0–5 V ADCs and logic without level-shifting; eliminates input clamping diodes |
| 1.3 mA per amplifier quiescent current | Supports four-channel analog signal path in space-constrained, thermally sensitive applications like ADAS camera modules |
| 80 ns settling to 0.1% at G = +2 | Meets timing budget for 12-bit SAR ADCs sampling at ≥10 MSPS with minimal acquisition delay |
| –79 dB crosstalk at 5 MHz (quad version) | Prevents inter-channel interference in multi-sensor synchronous sampling systems (e.g., stereo vision, multi-axis IMU) |
| Disable pin with 85 ns turn-on time | Allows dynamic channel gating in time-division multiplexed architectures without introducing switching transients |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed, low-power op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMH6612MMX/NOPB | Higher quiescent current (2.3 mA/ch), wider bandwidth (190 MHz), no disable function | Better for bandwidth-critical but less power-sensitive applications; lacks channel shutdown | Select if >150 MHz bandwidth required and disable functionality is unnecessary |
| ADA4891-4ARUZ | Lower supply current (1.2 mA/ch), lower bandwidth (100 MHz), same TSSOP-14 package | Better for ultra-low-power, moderate-bandwidth applications; slightly reduced settling speed (110 ns) | Select if power budget is tighter than 1.3 mA/ch and 100 MHz bandwidth suffices |
Compared with LMH6612MMX/NOPB and ADA4891-4ARUZ, the AD8040ARUZ uniquely balances 125 MHz bandwidth, 1.3 mA/ch consumption, and integrated disable control - making it optimal for battery-operated, multi-channel systems requiring dynamic power scaling and precise timing.

FAQ
What is the maximum operating supply voltage for the AD8040ARUZ?
The AD8040ARUZ supports a supply voltage range of 2.7 V to 12 V. Absolute maximum rating is 12.6 V across +VS and –VS pins. Operation above 12 V risks permanent damage; sustained operation near 12 V requires thermal derating per Figure 6 in the datasheet to maintain junction temperature below 150°C.
Does the AD8040ARUZ support true rail-to-rail input on a single +5 V supply?
Yes. On +5 V supply, the AD8040ARUZ input common-mode voltage range extends from –0.2 V to +5.2 V - 200 mV beyond both rails - with no phase reversal. This allows direct interfacing with sensors or DACs that output signals near ground or VCC without external level-shifting circuitry.
How many independent amplifiers does the AD8040ARUZ contain, and are their DISABLE functions shared?
The AD8040ARUZ contains four fully independent amplifiers in a single TSSOP-14 package. All four share a single active-low DISABLE pin (Pin 12); asserting it disables all channels simultaneously, reducing total quiescent current to ~560 µA (140 µA × 4).
What is the typical output voltage swing of the AD8040ARUZ when loaded with 1 kΩ on a +5 V supply?
At +5 V supply and RL = 1 kΩ tied to midsupply, the AD8040ARUZ delivers an output swing of –VS + 0.17 V to +VS – 0.17 V, i.e., 0.17 V to 4.83 V. This 4.66 V peak-to-peak range preserves >93% of the full 5 V supply rail, critical for maximizing ADC dynamic range.
Can the AD8040ARUZ drive capacitive loads, and what is the maximum stable value?
Yes. The AD8040ARUZ is specified to drive up to 15 pF capacitive load with ≤30% overshoot on +5 V supply (Table 2). For heavier loads, external series resistance (e.g., 10–50 Ω) at the output is recommended to maintain stability, especially in PCB trace or ADC input capacitor scenarios.
