The MAX9658AEE+T is a high-performance video output amp designed to boost video signal transmission without compromising signal integrity and stability. This video amplifier module is a building block of video applications like displays, home entertainment systems and other audio-video solutions.

The MAX9658AEE+T is a linear amplifier module found in the ‘Linear - Amplifiers - Video Amps and Modules’ category of video amplifiers. This 18-pin amplifier module includes an integrated charge pump, dual 5-pin headers for differential inputs, a single-ended output and onboard EEPROM for storing common settings such as input type, output modes, and maximum voltage compliance.

The MAX9658AEE+T operates in an asymmetrical push-pull output configuration whereby the device produces a balanced output signal by combining two amplifier stages, one driving the positive output swing the other with negative output swing, from a single ended input of either type. It is also configured to drive multiple output stages through voltage follower, hence eliminating the need of any external switching devices. It has a high slew rate of 15V/µs and a wide operating voltage range of 1.8V to 5.16V.

The MAX9658AEE+T device is designed to process video signals in a variety of today’s application-specific integrated circuits (ASICs), programming integrated circuits (PLDs), and stand-alone video processors. It is suitable for digital video output applications such as high definition digital video (HDDV) systems, DVD recording and playback systems, point-to-point video conferencing, and other professionals’ audio-video systems.

Technically speaking, the MAX9658AEE+T application field is focused on the combination of pin-compatible output stages that allow for performance tuning to meet specific needs, such as limiting differential input offset voltage, input common-mode voltage, and output swing. This allows designs to be optimized for the set of operating conditions and achieve maximum output voltage swing with minimum power dissipation.

The MAX9658AEE+T works based on a concept referred to as "Conjugate Matching". This involves amplifying the two halves of a signal in a manner such that any noise or distortion in one half of the signal is amplified in the other half, hence being nullified. It also minimizes the power dissipation of the device while simultaneously enhancing output performance.

The MAX9658AEE+T is ideal for applications like switching between multiple sources, or mixing and matching of video signals having different resolutions. It is also suitable for applications requiring input signal attenuation. Moreover, the device’s integrated ESD protection and low noise output reduces susceptibility to external and internal electrical noise.

In conclusion, the MAX9658AEE+T is a high-end video output amplifier module designed to optimize video signal transmission, eliminating noise and distortion from the signal. It is ideal for applications requiring reliable signal transmission such as HD video systems, DVD recorders and playback systems, video conferencing and other professional audio/video solutions. The device’s Conjugate Matching technology and integrated ESD protection makes it an ideal choice for a variety of linear video output applications.
