Product details
Overview
ADA4891-4ARUZ-R7 from Analog Devices is a quad-channel, rail-to-rail output CMOS high-speed operational amplifier optimized for video, imaging, and active filter applications. It delivers 220 MHz −3 dB bandwidth (G = +1), 170 V/µs slew rate, 28 ns settling time to 0.1%, 0.05% differential gain error, and operates from 2.7 V to 5.5 V single supply - enabling high-fidelity signal conditioning in automotive infotainment and contact image sensor buffers.
For engineers reviewing the ADA4891-4ARUZ-R7 datasheet, ADA4891-4ARUZ-R7 pinout, ADA4891-4ARUZ-R7 application, or ADA4891-4ARUZ-R7 equivalent, key selection criteria include its quad-channel TSSOP-14 package, rail-to-rail output swing within 50 mV of rails, low 4.4 mA per amplifier quiescent current, and verified NTSC video performance at 25 MHz 0.1 dB gain flatness.
Technical Context
The ADA4891-4ARUZ-R7 implements a fully differential-capable, unity-gain stable voltage-feedback architecture with true single-supply operation - input common-mode range extends 300 mV below negative rail, and output swings to within 50 mV of both supply rails. Its CMOS input stage provides 5 GΩ input resistance and only 3.2 pF input capacitance, minimizing loading on high-impedance sources like photodiodes or CCD outputs.
Designed for wideband signal paths, it maintains 79 dBc SFDR at 1 MHz and achieves −80 dB all-hostile crosstalk at 5 MHz, confirming robust channel isolation in multi-amplifier configurations. The device is specified across −40°C to +125°C and qualified for automotive applications, with no power-down functionality (unlike the ADA4891-3).
Key Specifications

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | +VS | Positive supply rail connection; must be bypassed locally with 0.1 µF ceramic capacitor to ground |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMH6629MA/NOPB | Higher 1.5 GHz GBW but bipolar input (2.5 µA Ibias), 12.5 mA IQ, no rail-to-rail output (clips ~1.2 V from rails) | Better for RF IF amplification; unsuitable for low-VOCM sensor interfaces or single-supply rail-to-rail designs | Choose LMH6629MA/NOPB only when ultra-wideband gain-setting (>500 MHz) is required and rail-to-rail output is unnecessary. |
| AD8054ARUZ | Similar quad SOIC/TSSOP footprint, 160 MHz BW, 1400 V/µs slew, but higher 12 mA IQ and no automotive qualification | Valid for industrial video; lacks AEC-Q100 rating and fails NTSC differential phase spec (0.25° vs. AD8054's 1.2°) | Select AD8054ARUZ only for non-automotive, cost-sensitive designs where 220 MHz bandwidth is not mandatory. |
Compared with LMH6629MA/NOPB and AD8054ARUZ, ADA4891-4ARUZ-R7 uniquely balances automotive qualification, rail-to-rail output, low power (4.4 mA), and broadcast-grade video specs - making it the only option qualified for safety-critical automotive display signal chains requiring <0.3° phase error.

FAQ
What is the operating temperature range for the ADA4891-4ARUZ-R7?
The ADA4891-4ARUZ-R7 is fully specified from −40°C to +125°C and qualified for automotive applications per AEC-Q100. All electrical parameters - including bandwidth, slew rate, and output swing - are guaranteed across this extended range, making ADA4891-4ARUZ-R7 suitable for under-hood and dashboard electronics where ambient temperatures exceed 105°C.
Does the ADA4891-4ARUZ-R7 support power-down functionality?
No, the ADA4891-4ARUZ-R7 does not include power-down pins. Unlike the ADA4891-3 (which features PD1–PD3 control inputs), the ADA4891-4ARUZ-R7 has no enable/disable capability - all four amplifiers remain active whenever power is applied. Pin 4 (PD2) is a no-connect terminal on ADA4891-4ARUZ-R7 and must be left unconnected.
Can the ADA4891-4ARUZ-R7 drive a 75 Ω coaxial cable directly?
Yes, the ADA4891-4ARUZ-R7 can drive 75 Ω coaxial cables directly. Its output delivers 125 mA linear current and maintains 0.05% differential gain error into 150 Ω loads - a condition more demanding than 75 Ω termination. For optimal return loss, use series 37.5 Ω source termination (or 75 Ω parallel termination at receiver end) per standard video interface practice.
What is the input common-mode voltage range of the ADA4891-4ARUZ-R7?
The ADA4891-4ARUZ-R7 features a rail-to-rail input stage with common-mode range extending from −VS − 0.3 V to +VS − 0.8 V. In a 5 V single-supply configuration (−VS = 0 V), this translates to −0.3 V to +4.2 V - allowing input signals to go 300 mV below ground and up to 800 mV below the positive rail, supporting true single-supply operation with AC-coupled or DC-coupled inputs.
Is the ADA4891-4ARUZ-R7 pin-compatible with other devices in the ADA4891 family?
The ADA4891-4ARUZ-R7 shares the same 14-lead SOIC_N and TSSOP pinout with the ADA4891-3, but is not functionally pin-compatible due to missing power-down pins. Pins labeled PD1–PD3 on ADA4891-3 are NC on ADA4891-4ARUZ-R7. Thus, while PCB footprints may be shared, firmware or external logic controlling power-down cannot be reused without modification.
