MAX9505ETE+T

Video Amps And Modules Overview

The MAX9505ETE+T is a DirectDrive video amplifier with an integrated reconstruction filter and analog switch, manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single supply voltage ranging from 2.7V to 3.6V. The device features a DC-coupled output that sets the video black level to ground without requiring large output-coupling capacitors. It provides a typical 6dB gain and includes a six-pole Butterworth lowpass filter for smoothing DAC output steps. An internal analog switch interfaces with multimedia jacks, offering configurable input/output modes.

Video Amps And Modules Feature Summary

• DirectDrive technology eliminates large output-coupling capacitors by using an integrated charge pump and linear regulator to create a negative power supply, allowing the video black level to be set precisely to ground.
• Includes a six-pole Butterworth reconstruction filter designed to smooth video signal steps and reduce spikes generated by digital-to-analog converters (DACs).
• Features an internal analog switch that interfaces with 4-pole multimedia jacks, enabling flexible configuration of poles as video inputs, video outputs, or microphone inputs.
• Provides a low-power shutdown mode that reduces quiescent supply current to typically 10nA, making it suitable for battery-powered portable applications.

Video Amps And Modules Applications

• Mobile Phones/Smartphones
• Space-Constrained, Low-Power Audio/Video Portable Devices

Video Amps And Modules Procurement Notes

Verify the specific suffix 'E' corresponds to the TQFN package and '+T' indicates tape-and-reel packaging when sourcing. Confirm the component meets RoHS compliance standards as indicated by the '+' suffix in the ordering information. Ensure the operating temperature range aligns with your application requirements, as this part is specified for extended temperatures.

Video Amps And Modules Selection Notes

Select the MAX9505ETE+T for applications requiring direct connection to video DACs without external coupling capacitors. Consider its space-saving 16-pin TQFN package for designs with strict board area limitations. Evaluate the need for the integrated analog switch if multimedia jack interfacing is required. Ensure the system can accommodate the necessary bypass capacitors for the charge pump and linear regulator to maintain performance.

Video Amps And Modules Part Context

The MAX9505 belongs to Maxim's DirectDrive family of video amplifiers, which focus on eliminating bulky passive components in video signal paths. This series integrates charge pumps and regulators to handle single-supply operation while maintaining AC-coupled performance characteristics. The MAX9505 specifically targets standard-definition video signals, combining amplification, filtering, and switching functions into a compact solution.

Video Amps And Modules Replacement Considerations

Check for updated versions within the MAX9505 family or similar DirectDrive video amplifiers from Analog Devices. Verify pin compatibility and electrical specifications before substituting with other models. Consult official documentation for any recommended upgrades or alternative parts with enhanced features or improved availability.
