AD829SQ

Overview

The AD829SQ is a high-speed, low-noise video operational amplifier manufactured by Analog Devices Inc. It features a gain-bandwidth product of 750 MHz and a slew rate of 230 V/µs. The device operates on supply voltages ranging from ±4.5V to ±18V with a typical supply current of 5.3 mA. It provides an input voltage noise density of 1.7 nV/√Hz and supports output currents up to 32 mA. The component is housed in an 8-SOIC package.

Feature Summary

• Customizable frequency response via external compensation pins for optimized bandwidth across various gains
• Low input voltage noise density suitable for precision signal processing applications
• Capable of driving reverse-terminated 50 Ω or 75 Ω cables effectively

Applications

• Professional video signal processing circuits
• High-speed data acquisition systems
• Buffer amplifiers for analog-to-digital converters

Procurement Notes

Verify the specific suffix 'SQ' against the official Analog Devices datasheet to confirm temperature range and packaging specifications. Ensure compatibility with existing board layouts regarding the SOIC-8 footprint. Confirm availability status through authorized distributors as lead times may vary. Validate that the component meets all required environmental standards for the intended deployment environment.

Selection Notes

Select this component when high bandwidth and low noise are critical requirements for video or fast transient signals. Consider the external compensation feature if gain adjustments are necessary without significant bandwidth loss. Evaluate power consumption constraints given the 5.3 mA supply current. Compare performance metrics against other video op-amps if higher drive capability or different package options are needed.
