Product details
Overview
AD8040ARZ-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 1.3 mA per amplifier quiescent current. It is used in A/D converter drivers, active filters, and automotive vision system buffers.
For engineers reviewing the AD8040ARZ-REEL7 datasheet, AD8040ARZ-REEL7 pinout, AD8040ARZ-REEL7 application, or AD8040ARZ-REEL7 equivalent, key selection criteria include rail-to-rail I/O swing within 40 mV of rails, input common-mode range extending 200 mV beyond supplies, crosstalk < –79 dB at 5 MHz, and SOIC-14 package compatibility with industrial temperature operation (–40°C to +125°C).
Technical Context
The AD8040ARZ-REEL7 employs Analog Devices' proprietary XFCB process to achieve high-speed performance at low power. Its voltage-feedback architecture supports stable operation with gain ≥ +1, featuring dual-input-stage topology (NPN/PNP) enabling rail-to-rail input without phase reversal up to ±200 mV beyond supply rails.
Each of the four amplifiers integrates independent output stages capable of driving 1 kΩ loads to within 170 mV of either rail at +5 V supply, while maintaining 79 dB crosstalk isolation between channels at 5 MHz - critical for multi-channel signal integrity in compact PCB layouts.

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 |
|---|---|---|---|
| LMH6644MA/NOPB | Higher quiescent current (2.3 mA/amplifier), wider bandwidth (135 MHz), no rail-to-rail input (input range limited to V– + 1.5 V to V+ – 1.5 V). | Less suitable for ground-referenced sensor signals or ultra-low-power portable designs. | Select when higher bandwidth and drive strength outweigh power and input range constraints. |
| ADA4891-4ARUZ | Lower bandwidth (105 MHz), lower quiescent current (1.2 mA/amplifier), rail-to-rail I/O, but only specified down to –40°C to +125°C with reduced AC performance at temperature extremes. | Acceptable for commercial-grade instrumentation but not automotive AEC-Q100 qualified systems. | Select for cost-sensitive, non-automotive applications where 105 MHz bandwidth suffices and AEC-Q100 qualification is unnecessary. |
Compared with LMH6644MA/NOPB and ADA4891-4ARUZ, AD8040ARZ-REEL7 uniquely combines AEC-Q100 qualification, true rail-to-rail input (including 200 mV beyond rails), and 125 MHz bandwidth at 1.3 mA - making it the only option meeting automotive vision system requirements without design compromises.

FAQ
What is the operating temperature range for AD8040ARZ-REEL7?
The AD8040ARZ-REEL7 is rated for operation from –40°C to +125°C across its full parameter set, including bandwidth, slew rate, and input offset voltage. This extended industrial temperature range is verified per the AD8040W automotive-grade variant specifications and applies to the AD8040ARZ-REEL7 in SOIC-14 packaging, making it suitable for under-hood automotive and industrial control environments where thermal stability is critical.
Does AD8040ARZ-REEL7 support true rail-to-rail input operation?
Yes, AD8040ARZ-REEL7 supports true rail-to-rail input operation with no phase reversal for input voltages extending 200 mV beyond either supply rail - e.g., from –0.2 V to +5.2 V on a +5 V supply. This capability is confirmed in the General Description and Input Characteristics sections of the Rev. B datasheet, enabling direct interfacing with ground-referenced sensors and logic-level signals without external level-shifting circuitry.
What is the typical quiescent current per amplifier in AD8040ARZ-REEL7?
The typical quiescent current per amplifier in AD8040ARZ-REEL7 is 1.3 mA at +5 V supply and 25°C, as specified in Table 2 (Specifications with +5 V Supply). Total device current is approximately 5.2 mA for all four amplifiers, enabling low-power operation in battery-powered instrumentation and portable test equipment where thermal management and runtime are critical design constraints.
Can AD8040ARZ-REEL7 drive heavy capacitive loads?
AD8040ARZ-REEL7 is characterized to drive up to 15 pF capacitive load with ≤30% overshoot at +5 V supply, as stated in Table 2. For larger loads, external isolation resistors (e.g., 10–50 Ω in series with the output) are recommended to maintain stability. The device's small-signal transient response degrades with increasing capacitance, as shown in Figure 28, so layout optimization and output filtering must be validated per application.
Is AD8040ARZ-REEL7 pin-compatible with other members of the AD80xx family?
No, AD8040ARZ-REEL7 is not pin-compatible with AD8029 (SOIC-8) or AD8030 (SOIC-8 or SOIC-14 dual variants); it uses a dedicated 14-pin SOIC footprint supporting four independent amplifiers. Pin mapping matches the SOIC-14 configuration shown in Figure 4 of the datasheet, with VOUT1–VOUT4, ±IN1–±IN4, and shared ±VS rails - distinct from the 8-pin dual or single packages in the same family.
