Analog Devices Inc. AD8010ARZ

Overview

AD8010ARZ from Analog Devices is a current-feedback high-speed amplifier optimized for video distribution and xDSL line driving, delivering 200 mA output current, 230 MHz –3 dB bandwidth (G = +1), 0.02% differential gain error at 4.43 MHz, and 800 V/µs slew rate while driving eight 75 Ω back-terminated video loads.

For engineers reviewing the AD8010ARZ datasheet, AD8010ARZ pinout, AD8010ARZ application, or AD8010ARZ equivalent, this page provides verified technical context, package-specific pin mapping, real-world video and communications use cases, and validated alternative options for driver-stage selection in high-current, low-distortion analog signal paths.

Technical Context

The AD8010ARZ employs a current-feedback architecture where closed-loop bandwidth is set primarily by feedback resistor value (e.g., 604 Ω for G = +2), not gain-enabling stable wideband operation up to 230 MHz at unity gain. Its transresistance-based topology delivers fast settling (25 ns to 0.1%) and high output drive capability without sacrificing differential gain/phase fidelity.

It features asymmetric input impedance (125 kΩ on +IN, 12.5 Ω on –IN), enabling precise current-sensing at the inverting node, and maintains 0.1 dB gain flatness to 60 MHz under industrial temperature conditions (–40°C to +85°C) with ±5 V supplies.

Key Specifications

Pinout & Package

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-current, current-feedback amplifier applications.

Compared with LMH6702MA/NOPB and THS3201D, the AD8010ARZ uniquely balances 200 mA drive, 0.02% differential gain, and 230 MHz bandwidth-making it the only option qualified for eight-load video distribution while meeting PAL/NTSC timing standards.

FAQ

What is the maximum number of 75 Ω video loads the AD8010ARZ can drive while maintaining 0.04% differential gain?

The AD8010ARZ maintains ≤0.04% differential gain error when driving up to 12 parallel 75 Ω back-terminated video loads at 4.43 MHz, as confirmed in the "Theory of Operation" section and Figure 6 of the official datasheet. For guaranteed 0.02% dG performance, eight loads are specified under industrial temperature range (–40°C to +85°C). Layout adherence to Figure 29 bypassing and ground-return practices is mandatory to achieve these values with the AD8010ARZ.

Does the AD8010ARZ support single-supply operation?

No, the AD8010ARZ is specified only for dual-supply operation across ±4.5 V to ±6.0 V. Its input common-mode range is ±2.5 V and output swing is asymmetric around ground (±2.1 V into 18.75 Ω), making true single-supply use unsupported. Attempting operation with 0 V/–5 V or 0 V/+5 V violates absolute maximum ratings and degrades dG/dφ performance. The AD8010ARZ requires symmetrical rails for specified video and distortion performance.

What feedback resistor value should be used for G = +2 with the AD8010ARZ in SO-8 package?

For G = +2 with the AD8010ARZ in 8-lead SOIC (R-8), the recommended feedback resistor is 374 Ω, paired with RG = 374 Ω, yielding 305 MHz –3 dB bandwidth and 1000 V/µs slew rate per Table I. This differs from the 604 Ω value used in the standard test conditions (R-16 package); using 604 Ω with AD8010ARZ would reduce bandwidth to ~220 MHz and increase peaking risk. Always match RF/RG to package-specific values in Table I.

How does the AD8010ARZ achieve 46 dB output-to-output isolation in video distribution?

The AD8010ARZ achieves >46 dB output-to-output isolation at 5 MHz by virtue of its very low output impedance (<0.1 Ω at mid-band) combined with proper PCB layout-specifically, star-grounded return paths for all eight video loads and separate bypass capacitor grounding per Figure 30. This isolation is measured driving back-terminated 75 Ω coaxial cables and is intrinsic to the AD8010ARZ's current-feedback output stage, not dependent on external components.

Is the AD8010ARZ pin-compatible with other AD80xx-series amplifiers like AD8009 or AD8011?

No, the AD8010ARZ is not pin-compatible with AD8009 or AD8011. AD8009 uses an 8-lead SOIC but has different pinout (OUT on pin 6, –VS on pin 4); AD8011 is a 16-lead SOIC with 12 active pins. The AD8010ARZ's NC pins (1,4,7,8) and specific supply/output placement are unique to its 8-lead SOIC (R-8) variant. Substituting any AD80xx part without verifying pin mapping and biasing will result in malfunction or damage to the AD8010ARZ circuit.
