AD8013ARZ-14-R7

Overview

The AD8013ARZ-14-R7 is a low power, single supply, triple video amplifier manufactured by Analog Devices Inc. It integrates three current feedback amplifiers in one package, optimized for driving back-terminated 150 Ω video loads. The device features a unity gain bandwidth of 140 MHz and a slew rate of 1000 V/µs. It operates on single supplies from +4.2 V to +13 V or dual supplies up to ±6.5 V. Each channel provides 30 mA output current with excellent video specifications including 0.02% differential gain error and 0.06° differential phase error at 3.58 MHz.

Procurement Notes

Verify the specific ordering suffix '-R7' against official documentation to confirm reel packaging requirements. Ensure the component matches the industrial temperature range of -40°C to +85°C. Confirm that the SOIC-14 package dimensions align with your PCB layout constraints. Cross-reference the manufacturer part number with authorized distributors to ensure authenticity.

Selection Notes

Select this component when multiple video channels are required in a compact form factor. It is suitable for applications demanding high bandwidth and fast settling times with low power consumption. Consider the current feedback architecture for customizable bandwidth via feedback resistors. Evaluate the disable pin functionality if multiplexing or power management is required.

Part Context

The AD8013 series includes variants such as the AD8013AN (DIP) and AD8013AR-14 (SOIC). The AD8013ARZ-14-R7 specifically denotes the SOIC-14 package variant supplied in a reel format. This family is designed for general-purpose high-speed applications requiring single or dual power supplies.

Replacement Considerations

Consult official datasheets for direct substitutes. Verify pin compatibility and electrical parameters before substitution.

FAQ

How does the AD8013 handle capacitive loads?

The AD8013 can drive large capacitive loads without oscillation when used with appropriate feedback resistors. Increasing the feedback resistor value improves phase margin for stability.

What is the function of the Disable pins?

Pulling a Disable pin approximately 1.6 V above the negative supply puts the corresponding amplifier into a powered-down state with high impedance output. Leaving it floating keeps the amplifier enabled.
