Replacement verdict
Not a drop-in replacement
The AD8075ARUZ and AD8072JR are not drop-in replacements for one another. Although both are triple high-speed video amplifiers from Analog Devices, they differ in package footprint, pin configuration, supply voltage range, and specified bandwidth and slew rate performance, so the AD8072JR cannot be substituted directly for the AD8075ARUZ without circuit and layout redesign.

Key electrical and mechanical differences between the two devices
| Parameter | AD8075ARUZ | AD8072JR | Why it matters |
|---|---|---|---|
| Number of Amplifiers | 3 | 2 | Determines how many independent signal channels can be processed in one package; a 3-channel part cannot be directly substituted where a 2-channel layout is required. |
| -3 dB Bandwidth | 500 MHz | 100 MHz | Sets the maximum signal frequency the amplifier can pass with acceptable gain; the much higher bandwidth of the AD8075ARUZ affects video and high-speed signal fidelity. |
| Slew Rate | 1350 V/µs | 300 V/µs | Governs how fast the output can respond to large signal steps; higher slew rate supports faster large-signal transitions and lower distortion at high frequencies. |
| Supply Voltage Range | ±4.5 V to ±5.5 V | ±4.5 V to ±5.5 V | Defines the allowable power supply rails; matching ranges allow both parts to operate in the same supply environment. |
| Package / Mounting | 14-Lead TSSOP (Surface Mount) | 8-Lead SOIC (Surface Mount) | Footprint and pin count must match the PCB layout; different packages require board redesign and cannot be drop-in substituted. |
| Output Current (per amplifier) | 30 mA | 30 mA | Determines the drive capability into loads such as cables or video terminations; equal drive strength supports similar load handling. |
| Operating Temperature Range | -40 °C to +85 °C | 0 °C to +70 °C | Specifies the ambient range over which specifications are guaranteed; the wider industrial range of the AD8075ARUZ suits harsher environments. |
| Input Voltage Noise | 4.5 nV/√Hz | 4.5 nV/√Hz | Affects the noise floor of the signal chain; comparable noise performance means similar low-level signal handling. |

Frequently asked questions
What are the primary differences between the AD8075ARUZ and the AD8072JR?
The AD8075ARUZ is a triple-channel, high-speed video amplifier with a fixed gain of 2, supplied in a 16-lead TSSOP package. The AD8072JR is a dual-channel, low-power, general-purpose operational amplifier with an adjustable gain configuration, supplied in an 8-lead SOIC package. The AD8075ARUZ is optimized for video signal processing with internal gain-setting resistors, while the AD8072JR is a conventional voltage-feedback op-amp intended for general signal conditioning.
Are the AD8075ARUZ and AD8072JR pin-compatible or directly interchangeable?
No. The AD8075ARUZ uses a 16-lead TSSOP package, while the AD8072JR uses an 8-lead SOIC package. The pin counts, pin functions, and package footprints differ, so these devices are not pin-compatible and cannot be directly substituted without a PCB redesign.
How do the channel counts of the AD8075ARUZ and AD8072JR compare?
The AD8075ARUZ integrates three independent amplifier channels in a single package, making it suitable for RGB video signal processing. The AD8072JR contains two independent amplifier channels, making it suitable for dual-channel signal conditioning applications.
What are the supply voltage requirements for the AD8075ARUZ and AD8072JR?
Both devices operate from dual power supplies. The AD8075ARUZ is specified for operation on ±5 V supplies. The AD8072JR is specified for operation on ±5 V supplies as well. Designers should consult the respective manufacturer datasheets for the complete operating supply range and absolute maximum ratings before finalizing a design.
Which device is better suited for video applications?
The AD8075ARUZ is specifically designed for video applications. It is a triple video amplifier with a fixed gain of 2, internal gain-setting resistors, and high slew rate and bandwidth characteristics optimized for driving video loads. The AD8072JR is a general-purpose dual op-amp and is not specifically characterized for video signal processing.
Can the AD8072JR be used to replace the AD8075ARUZ in an existing video design?
No, a direct replacement is not feasible. The AD8072JR has only two channels versus three on the AD8075ARUZ, uses a different package and pinout, and lacks the fixed gain-of-2 internal resistor network of the AD8075ARUZ. Replacing the AD8075ARUZ with the AD8072JR would require significant circuit and PCB redesign and would not preserve the original video signal chain architecture.
What are the package and mounting types for the AD8075ARUZ and AD8072JR?
The AD8075ARUZ is supplied in a 16-lead TSSOP (Thin Shrink Small Outline Package) surface-mount package. The AD8072JR is supplied in an 8-lead SOIC (Small Outline Integrated Circuit) surface-mount package. Both are surface-mount devices, but their footprints and land patterns are not interchangeable.
