Analog Devices Inc. AD8092ARMZ

Overview

AD8092ARMZ 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 50 ns settling to 0.1% on ±5 V or single +5 V supply, driving 45 mA while consuming only 4.4 mA per amplifier. It is used in professional camera signal chains and coaxial cable drivers where low distortion and wide dynamic range are critical.

For engineers reviewing the AD8092ARMZ datasheet, AD8092ARMZ pinout, AD8092ARMZ application, or AD8092ARMZ equivalent, key selection criteria include its rail-to-rail output swing (within 25 mV of rails), differential gain/phase error (0.03%/0.03° at RL = 1 kΩ), capacitive load drive capability (50 pF), and MSOP-8 package compatibility with space-constrained PCB layouts.

Technical Context

The AD8092ARMZ employs a voltage-feedback architecture with fully differential input stage and Class AB output stage, enabling fast overdrive recovery (≤60 ns) and stable operation into 150 Ω loads. Its input common-mode range extends 200 mV below the negative rail and within 1 V of the positive rail, supporting true single-supply operation down to +3 V.

Designed for unity-gain stability, it maintains ≥50° phase margin across supply voltages (+3 V to ±5 V) and load conditions (RL = 150 Ω to 10 kΩ). The dual-channel layout minimizes crosstalk (−60 dB at 5 MHz), preserving channel isolation in multi-signal video routing and active filter topologies.

FAQ

What supply voltages does the AD8092ARMZ support?

The AD8092ARMZ operates from single +3 V to +12 V supplies or dual ±5 V supplies. At +5 V, it achieves 110 MHz bandwidth and 145 V/μs slew rate; at +3 V, bandwidth remains 110 MHz with 135 V/μs slew rate. Input common-mode range extends 200 mV below −VS and within 1 V of +VS, enabling true single-supply functionality. The AD8092ARMZ maintains specified performance across −40°C to +85°C.

Does the AD8092ARMZ require external compensation for stability?

No, the AD8092ARMZ is unity-gain stable and requires no external compensation components. It maintains ≥50° phase margin into 150 Ω loads and drives up to 50 pF capacitive loads at G = +1 without oscillation. Layout best practices - including 0.1 μF and 0.01 μF bypass capacitors placed near +VS/−VS pins - ensure stability across all operating conditions. The AD8092ARMZ datasheet confirms stability under all tested configurations in Tables 1–3.

What is the maximum output current capability of the AD8092ARMZ?

The AD8092ARMZ delivers 45 mA continuous output current into loads referenced to mid-supply (e.g., 2.5 V on +5 V system), with short-circuit current of 80 mA (sourcing) and 130 mA (sinking) at +5 V. Output saturation voltage remains ≤25 mV from rails at 45 mA, enabling full dynamic range utilization. This capability supports direct driving of 75 Ω coaxial lines and 150 Ω video terminations without external buffers. The AD8092ARMZ sustains this performance across −40°C to +85°C.

How does the AD8092ARMZ perform in video applications like NTSC/PAL?

The AD8092ARMZ meets broadcast video specifications: 0.03% differential gain error and 0.03° differential phase error at 3.58 MHz (NTSC) with RL = 1 kΩ, and 0.09%/0.19° at RL = 150 Ω. Its 20 MHz 0.1 dB gain flatness (G = +2) and −80 dBc THD at 1 MHz ensure minimal color distortion and luminance artifacts. These values are measured per SMPTE 170M and are guaranteed across temperature and supply variations. The AD8092ARMZ is explicitly listed in Applications for professional cameras and video switchers.

Is the AD8092ARMZ pin-compatible with other dual op amps in MSOP-8?

The AD8092ARMZ uses a nonstandard pinout: OUT1, −IN1, +IN1, −VS, +VS, OUT2, −IN2, +IN2. It is not pin-compatible with generic dual op amps (e.g., AD8602, LMV722) that follow industry-standard SOIC/MSOP pinouts. Direct replacement requires PCB layout revision. The AD8092ARMZ datasheet Figure 3 explicitly defines this arrangement for MSOP-8 (RM-8), and no manufacturer documentation claims pin compatibility with alternate dual op amps.
