Analog Devices Inc. AD8056ARZ-REEL7

Overview

AD8056ARZ-REEL7 from Analog Devices is a dual, low-cost, voltage-feedback operational amplifier optimized for high-speed video and imaging applications. It delivers 300 MHz −3 dB bandwidth (G = +1), 1400 V/μs slew rate, 20 ns settling to 0.1%, 6 nV/√Hz input voltage noise, and drives ≥60 mA into 150 Ω loads - enabling use in professional camera video line drivers and differential ADC front-ends.

For engineers reviewing the AD8056ARZ-REEL7 datasheet, AD8056ARZ-REEL7 pinout, AD8056ARZ-REEL7 application, or AD8056ARZ-REEL7 equivalent, key selection criteria include its 8-lead MSOP package, ±5 V / +12 V supply compatibility, 0.01% differential gain error at 150 Ω, −72 dBc THD @ 10 MHz, and guaranteed operation from −40°C to +125°C.

Technical Context

The AD8056ARZ-REEL7 implements a classic voltage-feedback architecture with symmetrical dual amplifiers sharing common power rails. Each channel features rail-to-rail output swing (±3.1 V into 150 Ω), 10 MΩ input resistance, and 2 pF input capacitance - supporting stable unity-gain and G = +2 configurations without external compensation.

Its internal design enables simultaneous high bandwidth and low distortion: 40 MHz 0.1 dB gain flatness, −60 dB crosstalk between outputs at 5 MHz, and CMRR > 82 dB at DC - making it suitable for multi-channel video routing and single-ended-to-differential conversion where channel isolation and timing fidelity are critical.

FAQ

What is the maximum capacitive load the AD8056ARZ-REEL7 can drive stably?

The AD8056ARZ-REEL7 remains stable driving up to 30 pF of capacitive load with a 100 Ω resistive load at G = +2, as verified in Figure 39 of the Rev. J datasheet. For larger loads, a series resistor (RS) between 10 Ω and 35 Ω - selected per Figure 41 - restores stability without compromising bandwidth. This behavior is consistent across both channels of the AD8056ARZ-REEL7.

Does the AD8056ARZ-REEL7 support single-supply operation?

Yes, the AD8056ARZ-REEL7 operates on a single +12 V supply (with −VS grounded), delivering rail-to-rail output swing of ±3.1 V into 150 Ω. Input common-mode range extends to ±3.2 V, allowing direct interfacing with 0–2.5 V or 0–3.3 V sensor outputs. All AC performance specs - including 300 MHz bandwidth and 20 ns settling - are validated under both ±5 V dual and +12 V single-supply conditions for the AD8056ARZ-REEL7.

What is the thermal resistance (θ_JA) of the AD8056ARZ-REEL7 in its MSOP package?

The AD8056ARZ-REEL7 in the 8-lead MSOP (RM-8) package has a typical junction-to-ambient thermal resistance (θ_JA) of 160°C/W with standard JEDEC 2-layer board layout. At 12 mA quiescent current and ±5 V supplies, this yields a ~10°C rise above ambient. Derating curves in Figure 5 confirm safe operation up to 125°C ambient when power dissipation remains below 325 mW - a limit fully respected by the AD8056ARZ-REEL7 under typical video line driving conditions.

Can the AD8056ARZ-REEL7 replace the AD8056ARM in existing designs?

Yes, AD8056ARZ-REEL7 is a direct replacement for AD8056ARM: both are identical in electrical specifications, pinout, and MSOP-8 (RM-8) package dimensions. The "Z" suffix denotes Pb-free construction, and "-REEL7" indicates 7-inch tape-and-reel packaging - fully compatible with automated SMT placement. No PCB or schematic changes are needed when migrating from AD8056ARM to AD8056ARZ-REEL7.

How does the AD8056ARZ-REEL7 perform in differential line driver configurations?

In cross-coupled differential driver mode (Figure 37), the AD8056ARZ-REEL7 achieves 0.02% differential gain error and 0.1° phase error driving four 75 Ω video loads. Its matched channel characteristics - including <0.5 mV input offset mismatch and −60 dB output crosstalk - ensure precise complementary signal generation. This makes the AD8056ARZ-REEL7 ideal for driving twisted-pair video links or differential-input ADCs without external trimming.
