Analog Devices Inc. AD8058ARZ-REEL7

Overview

AD8058ARZ-REEL7 from Analog Devices is a dual, voltage-feedback operational amplifier optimized for high-speed, low-noise signal conditioning in video and data acquisition systems. It delivers 325 MHz −3 dB bandwidth (G = +1), 1000 V/µs slew rate, 7 nV/√Hz input voltage noise, and −85 dBc harmonic distortion at 5 MHz - enabling precision analog-to-digital driving and composite video filtering in professional imaging equipment.

For engineers reviewing the AD8058ARZ-REEL7 datasheet, AD8058ARZ-REEL7 pinout, AD8058ARZ-REEL7 application, or AD8058ARZ-REEL7 equivalent, key selection criteria include its dual-channel SOIC-8 package, ±1.5 V to ±6 V or 3 V to 10 V supply flexibility, 30 ns settling time to 0.1%, and verified NTSC differential gain/phase performance (0.01% / 0.15°) with 150 Ω load.

Technical Context

The AD8058ARZ-REEL7 implements a voltage-feedback architecture with rail-to-rail output swing capability (±3.9 V into 150 Ω) and low input bias current (0.5–2.5 µA). Its internal compensation enables stable operation up to 69 pF capacitive load at G = +2 without external isolation resistors.

It supports single-supply (3–10 V) and split-supply (±1.5–±6 V) configurations, features 48–60 dB CMRR, and maintains 0.1 dB gain flatness to 28 MHz - making it suitable for DC-coupled differential ADC drivers where midsupply common-mode bias (e.g., 2.5 V for AD9225) must be preserved across both channels.

FAQ

What is the maximum capacitive load the AD8058ARZ-REEL7 can drive stably at G = +2?

The AD8058ARZ-REEL7 sustains stable operation with up to 69 pF capacitive load at closed-loop gain +2, as confirmed in Figure 43 of the Rev. E datasheet. This allows direct interfacing with ADC input capacitance and short coaxial runs without added series isolation resistors - provided layout follows high-speed guidelines including minimized inverting input parasitics.

Does the AD8058ARZ-REEL7 support single-supply operation?

Yes, the AD8058ARZ-REEL7 operates from a single 3 V to 10 V supply, with input common-mode range extending from 0.9 V to 3.4 V (at VS = 5 V) and output swing from 0.9 V to 3.8 V into 2 kΩ. This enables true single-supply use in portable video and instrumentation systems without level-shifting circuitry.

What is the guaranteed operating temperature range for AD8058ARZ-REEL7?

The AD8058ARZ-REEL7 is rated for industrial operation from −40°C to +85°C, as stated in the Ordering Guide and Absolute Maximum Ratings tables. All specifications in the Rev. E datasheet - including bandwidth, distortion, and settling time - are guaranteed across this full range.

How does the AD8058ARZ-REEL7 achieve low differential phase error in video applications?

The AD8058ARZ-REEL7 achieves 0.15° differential phase error at NTSC frequencies via tightly matched internal transistor pairs, low input capacitance asymmetry (<0.2 pF), and optimized frequency response flatness (0.1 dB to 28 MHz). These design elements minimize group delay variation across luminance/chrominance bands - critical for maintaining color fidelity in composite video signals.

Is the AD8058ARZ-REEL7 pin-compatible with other dual op amps in SOIC-8 packages?

No - the AD8058ARZ-REEL7 uses a proprietary pinout (OUT1, −IN1, +IN1, −VS, +VS, OUT2, −IN2, +IN2) that differs from industry-standard dual op amp configurations like the LM358 or TL082. Direct replacement requires PCB layout revision; however, its pin mapping is identical to other AD8058 variants (e.g., AD8058AR, AD8058ARMZ) and matches the functional layout shown in Figure 3 of the datasheet.
