Analog Devices Inc. AD8092ARMZ-REEL7

Overview

AD8092ARMZ-REEL7 from Analog Devices is a dual, rail-to-rail output, voltage-feedback 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 up to 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-REEL7 datasheet, AD8092ARMZ-REEL7 pinout, AD8092ARMZ-REEL7 application, or AD8092ARMZ-REEL7 equivalent, key selection criteria include rail-to-rail output swing (within 25 mV of rails), capacitive load drive capability (50 pF at G = +1), differential gain/phase error (0.03%/0.03° at RL = 1 kΩ), and MSOP-8 package compatibility with space-constrained PCB layouts.

Technical Context

The AD8092ARMZ-REEL7 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 reactive 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 (±5 V, +5 V, +3 V) and load conditions (RL = 150 Ω to 10 kΩ). The amplifier's 1.4 pF input capacitance and 290 kΩ input resistance are optimized for minimal peaking in active filter and video line driver configurations.

FAQ

What supply voltage ranges does the AD8092ARMZ-REEL7 support?

The AD8092ARMZ-REEL7 operates from a single +3 V to +12 V supply or dual ±5 V supplies. At +5 V, it delivers full 110 MHz bandwidth and 145 V/μs slew rate; at +3 V, bandwidth remains 110 MHz with 135 V/μs slew rate. Absolute maximum supply is 12.6 V. The device maintains rail-to-rail output swing and specified distortion performance across this entire operating range, making AD8092ARMZ-REEL7 suitable for both battery-powered and fixed-line equipment.

Does AD8092ARMZ-REEL7 support rail-to-rail input operation?

No, AD8092ARMZ-REEL7 features rail-to-rail *output* 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 true single-supply operation with ground-referenced inputs in many video and sensor interfaces, but inputs must remain within that defined window to avoid clipping or increased offset. The AD8092ARMZ-REEL7 data sheet explicitly states "input voltage range extending 200 mV below the negative rail and within 1 V of the positive rail."

What is the maximum capacitive load the AD8092ARMZ-REEL7 can drive stably?

The AD8092ARMZ-REEL7 is characterized to drive up to 50 pF capacitively loaded at unity gain (G = +1) without external compensation, as confirmed in Table 1 and Figure 29–31 of the datasheet. At higher gains (G ≥ +2), it tolerates larger capacitive loads due to improved phase margin. For loads exceeding 50 pF at G = +1, a small series resistor (e.g., 3 Ω) between output and load restores stability. This capability enables direct connection to long PCB traces, connectors, or unterminated cables-critical for AD8092ARMZ-REEL7 deployment in video line drivers and active filter nodes.

How does AD8092ARMZ-REEL7 perform in NTSC video applications?

AD8092ARMZ-REEL7 meets broadcast-grade NTSC requirements: 0.03% differential gain error and 0.03° differential phase error at RL = 1 kΩ, and 0.09%/0.19° at 150 Ω load. It achieves 0.1 dB gain flatness to 20 MHz with RL = 150 Ω, supporting full-color fidelity in composite video distribution. These values are measured under standard NTSC test conditions (G = +2, f = 3.58 MHz) and are guaranteed across temperature. As such, AD8092ARMZ-REEL7 is validated for professional camera outputs, video switchers, and sync stripper circuits where color accuracy is essential.

Is the AD8092ARMZ-REEL7 pin-compatible with other dual op amps in MSOP-8?

AD8092ARMZ-REEL7 uses a nonstandard pinout for dual op amps: OUT1/–IN1/+IN1/–VS/+VS/+IN2/–IN2/OUT2. It is *not* pin-compatible with industry-standard dual op amps like the AD8602 or OP2177, which place +IN2/–IN2/OUT2 on pins 5/6/7. Substituting AD8092ARMZ-REEL7 into existing MSOP-8 footprints requires PCB redesign to match its unique pin mapping. The datasheet Connection Diagram (Figure 3) confirms this arrangement, and no manufacturer documentation claims pin compatibility with alternate dual op amp families.
