AD8023AR-REEL

Overview

The AD8023AR-REEL is a high current output, triple video amplifier manufactured by Analog Devices Inc. It features three independent current feedback amplifiers in a 14-lead SOIC package. Key electrical parameters include a unity gain bandwidth of 250 MHz and a slew rate of 1200 V/µs. Each amplifier provides a maximum output current of 70 mA and can drive capacitive loads up to 1000 pF. The device operates on supply voltages ranging from ±2.5 V to ±7.5 V (single supply +4.2 V to +15 V) with a quiescent current of 10.0 mA per amplifier. It includes a high-speed disable function for power-down or high-impedance states.

Feature Summary

• High current output capability of 70 mA per channel optimized for driving large capacitive loads without oscillation.
• Integrated high-speed disable function allows individual amplifier power-down or high-impedance output control.
• Excellent video specifications including low differential gain error and phase error for signal integrity.
• Wide output voltage swing approaching the supply rails to accommodate standard video signal levels.

Applications

• LCD Displays
• Video Line Driver
• Broadcast and Professional Video
• Computer Video Plug-In Boards
• RGB Amplifier in Component Systems

Procurement Notes

Verify the specific ordering suffix matches the required packaging format, as the base part number may be available in tube or different reel lengths. Confirm the temperature range and grade correspond to the application environment. Ensure ESD precautions are observed during handling due to the sensitivity of the input stages. Cross-reference the datasheet revision to confirm pinout and electrical characteristics remain consistent with design requirements.

Selection Notes

Select this component for applications requiring high-speed video signal processing with significant capacitive load driving capabilities. The current feedback architecture offers wide bandwidth independent of closed-loop gain settings. Consider the integrated disable feature for multiplexing applications where power consumption or output isolation is critical. Evaluate the supply voltage range to ensure compatibility with single or dual supply systems.

Part Context

This component belongs to the AD8023 family of triple video amplifiers. It is designed for high-performance analog video signal chains. The REEL suffix indicates tape and reel packaging for automated assembly. It competes in the high-speed video amplifier market segment, offering a balance of speed, current drive, and low distortion.

Replacement Considerations

Check for direct pin-compatible substitutes within the Analog Devices portfolio that offer similar current drive and bandwidth. Verify if alternative packages or temperature grades are available if the current specification does not meet mechanical or environmental constraints.

FAQ

How does the AD8023 handle large capacitive loads?

The AD8023 is optimized to drive unlimited capacitive load without oscillation when used with appropriate feedback resistors. A small series output resistor is recommended for optimal pulse response stability.

What is the function of the Disable pins?

Pulling a Disable pin approximately 1.6 V above the negative supply voltage powers down the corresponding amplifier and places its output in a high-impedance state. Leaving the pin floating keeps the amplifier enabled.
