Analog Devices Inc. AD8092ARZ

Overview

AD8092ARZ from Analog Devices is a dual, voltage-feedback, rail-to-rail output operational amplifier optimized for high-speed video and portable applications. It delivers 110 MHz −3 dB bandwidth (G = +1), 145 V/μs slew rate, and 25 mV rail-to-rail output swing at 5 V supply - enabling full dynamic range in composite video line drivers and active filters.

For engineers reviewing the AD8092ARZ datasheet, AD8092ARZ pinout, AD8092ARZ application, or AD8092ARZ equivalent, key selection criteria include its 50 ns settling time to 0.1%, 45 mA output drive capability into 150 Ω, and verified performance across +3 V, +5 V, and ±5 V supplies with input common-mode range extending 200 mV below negative rail.

Technical Context

The AD8092ARZ employs a voltage-feedback architecture with fully differential input stage and Class AB output stage, supporting stable operation at unity gain (G = +1) while driving up to 50 pF capacitive loads. Its input common-mode voltage range spans −0.2 V to +4.0 V on +5 V supply, enabling single-supply operation without level-shifting circuitry.

Designed for low-distortion signal conditioning, it achieves −80 dBc THD at 1 MHz (RL = 100 Ω), 0.03% differential gain/phase error (NTSC, RL = 1 kΩ), and 72–88 dB CMRR over 0–3.5 V common-mode range - making it suitable for professional camera front-ends and CCD imaging signal chains where timing integrity and amplitude fidelity are critical.

Key Specifications

FAQ

What supply voltage ranges does the AD8092ARZ support?

The AD8092ARZ operates from a single +3 V to +12 V supply or dual ±5 V supplies. At +3 V, it maintains 70 MHz bandwidth and 90 V/μs slew rate; at ±5 V, bandwidth reaches 110 MHz and slew rate increases to 170 V/μs. Quiescent current remains within 4.2–5.5 mA per amplifier across all supported supply configurations, ensuring predictable power budgeting in multi-voltage systems.

Does the AD8092ARZ support true rail-to-rail input operation?

The AD8092ARZ features rail-to-rail *output* swing but not rail-to-rail *input*. Its input common-mode voltage range extends 200 mV below the negative rail and within 1 V of the positive rail - for example, −0.2 V to +4.0 V on a +5 V supply. This allows direct interface with AC-coupled video signals referenced to ground while maintaining DC accuracy, but prohibits direct connection of inputs to the positive supply rail without attenuation or clamping.

Can the AD8092ARZ drive 75 Ω coaxial cables directly?

Yes, the AD8092ARZ can drive 75 Ω coaxial cables directly when configured as a unity-gain line driver with proper termination. Its 45 mA output current capability and 0.03% differential phase error at 1 kΩ load (scalable to 75 Ω with minor degradation) meet SMPTE RP 168 requirements for short-haul video distribution. For optimal return loss, use series 75 Ω source termination at the amplifier output and parallel 75 Ω termination at the load end.

What is the maximum capacitive load the AD8092ARZ can drive stably?

The AD8092ARZ drives up to 50 pF capacitive load stably in unity-gain configuration (G = +1) without external compensation, as verified in Figure 29 and Figure 30 of the datasheet. For loads exceeding 50 pF, a small series resistor (e.g., 3–10 Ω) between the output and load restores phase margin. This capability enables direct connection to ADC input capacitors, LCD column drivers, and long PCB traces without added isolation stages.

How does the AD8092ARZ perform in NTSC video applications?

The AD8092ARZ delivers 0.03% differential gain error and 0.03° differential phase error under NTSC conditions (G = +2, RL = 1 kΩ), meeting ITU-R BT.470 broadcast standards. Its 20 MHz 0.1 dB gain flatness and −80 dBc THD at 1 MHz ensure minimal color distortion and luminance nonlinearity in composite video paths - validated in professional camera and video switcher implementations per Analog Devices Application Note AN-742.
