MAX9509 - DirectDrive Video Filter Amplifiers

Description

Operating from a 1.8V single power supply, the MAX9509/ MAX9510 amplify standard-definition video signals and only consume 5.8mW quiescent power and 11.7mW average power.

The MAX9509/MAX9510 leverage Maxim’s DirectDrive® technology to generate a clean, internal negative supply.

Features

  • an internal reconstruction filter that smoothes the steps and reduces the spikes on the video signal from the video digital-to-analog converter (DAC). The reconstruction filter typically has ±1dB passband flatness of 8.1MHz and 46dB attenuation at 27MHz. The large-signal, ±1dB passband flatness of the MAX9510 video amplifier is typically 8.4MHz, and the large signal -3dB frequency is typically 11.4MHz. The input of the MAX9509/MAX9510 can be directly connected to the output of a video DAC. The M.

MAX9509/MAX9510 EVALUATION KIT AVAILABLE 1.8V, Ultra-Low Power, DirectDrive Video Filter Amplifiers General Description Operating from a 1.8V single power supply, the MAX9509/ MAX9510 amplify standard-definition video signals and only consume 5.8mW quiescent power and 11.7mW average power. The MAX9509/MAX9510 leverage Maxim’s DirectDrive® technology to generate a clean, internal negative supply. Combining the internal negative power supply with the external positive 1.8V supply, the MAX9509/ MAX9510 are able to drive a 2VP-P video signal into a 150Ω load. Besides increasing the output voltage range, Maxim’s DirectDrive technology eliminates large output-coupling capacitors and sets the output video black level near ground.
