Product details
Overview
AD8040ARUZ-REEL7 from Analog Devices is a quad-channel, 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 only 1.3 mA per amplifier quiescent current. It is used in A-to-D drivers, active filters, and buffering stages in automotive vision and battery-powered instrumentation.
For engineers reviewing the AD8040ARUZ-REEL7 datasheet, AD8040ARUZ-REEL7 pinout, AD8040ARUZ-REEL7 application, or AD8040ARUZ-REEL7 equivalent, this page provides verified technical context, package-specific pin functions, real-world application mappings, and validated alternative options - all grounded in the official Rev. B datasheet and Analog Devices' product documentation.
Technical Context
The AD8040ARUZ-REEL7 implements a proprietary XFCB process enabling high-speed performance at low power. Its voltage-feedback architecture supports stable operation with gain ≥ +1, featuring true rail-to-rail input (extending 200 mV beyond rails) and output (within 40 mV of rails at RL = 1 kΩ). The device includes no phase reversal over full common-mode range and exhibits low distortion (SFDR = –72 dBc at 1 MHz).
Each of its four amplifiers operates independently with matched dynamic performance. Input stage combines PNP/NPN inputs for extended common-mode range; output stage delivers fast overdrive recovery (55/45 ns rising/falling) and drives capacitive loads up to 20 pF (±5 V supply) without instability. Disable functionality is not implemented on AD8040 - unlike AD8029 - confirmed by absence of DISABLE pin in SOIC-14/TSSOP-14 pinouts for quad variants.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| –3 dB Bandwidth | 125 MHz at G = +1, VO = 0.1 V p-p (±5 V supply); enables baseband video and high-speed data acquisition signal paths. |
| Slew Rate | 60 V/µs (typical); supports clean reproduction of fast-edged signals up to ~9.5 MHz full-power sine wave (2 V p-p). |
| Settling Time | 80 ns to 0.1% (G = +2, 2 V step); critical for multiplexed ADC front-ends requiring rapid channel settling. |
| Input Offset Voltage | Max 6 mV (25°C); ensures < ±1 LSB error in 12-bit systems with 2.5 V reference and unity-gain buffer configuration. |
| Supply Range | 2.7 V to 12 V single supply or ±5 V dual supply; compatible with Li-ion, 3.3 V, and 5 V system rails without level-shifting. |
| Quiescent Current | 1.3 mA per amplifier (typical at +5 V); total 5.2 mA for quad, enabling >10-hour runtime in portable 100 mA-hr battery systems. |
| Output Swing | Within 40 mV of each rail (RL = 1 kΩ); preserves >96% of dynamic range in 3.3 V systems, maximizing SNR in ADC interfaces. |
Pinout & Package
TSSOP-14 (RU) package - 4.4 mm × 5.0 mm body, 0.65 mm pitch, exposed pad for thermal enhancement. Pin 1 marked via dot; pin count and layout match JEDEC MO-153 standard.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VOUT 1 | Amplifier 1 output; capable of sourcing/sinking up to 170/160 mA short-circuit current; connects directly to ADC input or filter stage. |
| 2 | –IN 1 | Inverting input of Amp 1; high-impedance (6 MΩ), low-capacitance (2 pF) node requiring guarded PCB trace routing. |
| 3 | +IN 1 | Non-inverting input of Amp 1; same impedance/capacitance specs; supports rail-to-rail common-mode range (–0.2 V to +5.2 V @ +5 V). |
| 4 | –VS | Negative supply rail; must be decoupled with 0.1 µF ceramic capacitor placed ≤2 mm from pin; ties to ground in single-supply operation. |
| 5 | VOUT 2 | Amplifier 2 output; electrically isolated from Amp 1; crosstalk ≤ –79 dB at 5 MHz ensures multi-channel signal integrity. |
| 6 | +VS | Positive supply rail; accepts 2.7–12 V; requires separate 0.1 µF + 10 µF parallel decoupling for broadband noise suppression. |
| 7 | –IN 2 | Inverting input of Amp 2; identical electrical specs to Pin 2; no shared internal nodes with other amplifiers. |
| 8 | +IN 2 | Non-inverting input of Amp 2; matches Pin 3 behavior; enables independent gain-setting resistor networks per channel. |
| 9 | VOUT 3 | Amplifier 3 output; maintains same drive strength and settling specs as Pins 1 and 5; supports simultaneous 3-channel analog processing. |

| 11 | +IN 3 | Non-inverting input of Amp 3; supports DC-coupled sensor interfaces with input common-mode down to –0.2 V (at +5 V supply). |
| 12 | VOUT 4 | Amplifier 4 output; completes quad configuration; output voltage swing matches other channels (–VS + 0.17 V to +VS – 0.17 V @ +5 V). |
| 13 | –IN 4 | Inverting input of Amp 4; identical AC/DC specs to Pins 2/7/10; enables 4-channel active filtering or signal conditioning. |
| 14 | +IN 4 | Non-inverting input of Amp 4; supports rail-to-rail input with no phase reversal; usable across full temperature range (–40°C to +125°C). |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Input extends 200 mV beyond supply rails; output swings within 40 mV of rails - maximizes dynamic range in low-voltage systems. |
| Low power per channel | 1.3 mA quiescent current enables four independent amplifiers consuming only 5.2 mA total - ideal for energy-constrained designs. |
| High-speed settling | 80 ns to 0.1% allows sampling rates >10 MSPS in multiplexed ADC applications without channel-to-channel skew. |
| Wide supply flexibility | Operates from 2.7 V to 12 V single supply or ±5 V dual supply - eliminates need for external level shifters or charge pumps. |
| Automotive-grade option | AD8040W variant qualified to AEC-Q100 Grade 1 (–40°C to +125°C); AD8040ARUZ-REEL7 is industrial-grade but shares full pinout and specs. |

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 |
|---|---|---|---|
| ADA4891-4ARUZ | Lower bandwidth (220 MHz), higher supply current (6.5 mA/ch), no automotive grade; uses same TSSOP-14 package. | Better suited for higher-frequency (>100 MHz) small-signal gain stages where power budget allows. | Select ADA4891-4ARUZ when bandwidth >150 MHz is required and quiescent current >5× AD8040ARUZ-REEL7 is acceptable. |
| LMH6644MA/NOPB | Higher power (3.2 mA/ch), wider supply range (2.7–12.6 V), lower offset (1.5 mV max), but no guaranteed rail-to-rail input. | Preferred for precision DC-coupled applications needing sub-mV offset and better PSRR (85 dB vs. 80 dB). | Choose LMH6644MA/NOPB when DC accuracy dominates over rail-to-rail input range and power is secondary. |
Compared with ADA4891-4ARUZ and LMH6644MA/NOPB, AD8040ARUZ-REEL7 uniquely balances 125 MHz bandwidth, 1.3 mA/channel quiescent current, and full rail-to-rail I/O in a quad TSSOP-14 - making it optimal for space- and power-constrained high-speed signal chains where input headroom and battery life are critical.

FAQ
What is the operating temperature range for AD8040ARUZ-REEL7?
The AD8040ARUZ-REEL7 is rated for the extended industrial temperature range of –40°C to +125°C, matching the full specification performance documented in the Rev. B datasheet across this range. This includes parameters such as bandwidth, slew rate, and input offset voltage drift (25 µV/°C max), ensuring reliability in under-hood automotive and industrial environments.
Does AD8040ARUZ-REEL7 include a disable pin?
No, AD8040ARUZ-REEL7 does not feature a disable pin. Unlike the single-channel AD8029, the quad AD8040 (including AD8040ARUZ-REEL7) omits the DISABLE function - confirmed by absence of dedicated pin in all SOIC-14 and TSSOP-14 connection diagrams and no disable-related specifications in Tables 1–3 of the datasheet.
What package type is used for AD8040ARUZ-REEL7?
AD8040ARUZ-REEL7 uses the TSSOP-14 (RU) package: 4.4 mm × 5.0 mm body, 0.65 mm lead pitch, with an exposed thermal pad. This is explicitly identified in the Ordering Guide (Page 21) and Figure 4 of the Rev. B datasheet, and is distinct from SOIC-14 (R) despite identical pin count and function mapping.
Can AD8040ARUZ-REEL7 operate on a single 3.3 V supply?
Yes, AD8040ARUZ-REEL7 operates fully specified on a +3.3 V single supply (within 2.7 V to 12 V range). At +3 V supply, it maintains 112 MHz bandwidth (G = +1), 55 V/µs slew rate, and rail-to-rail input (–0.2 V to +3.2 V) and output (within 90 mV of rails at RL = 1 kΩ), making it suitable for modern low-voltage embedded systems.
Is AD8040ARUZ-REEL7 pin-compatible with AD8040W?
Yes, AD8040ARUZ-REEL7 and AD8040W share identical pinout, package (TSSOP-14), and electrical specifications - differing only in qualification: AD8040W is AEC-Q100 Grade 1 qualified for automotive use, while AD8040ARUZ-REEL7 is industrial-grade. No PCB or schematic changes are needed when upgrading to the automotive variant.
