Overview
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.
DirectDrive requires an integrated charge pump and an internal linear regulator to create a clean negative power supply so that the amplifier can pull the sync below ground.
The charge pump injects little noise into the video output, making the picture visibly flawless.
The MAX9509/MAX9510 are designed to operate from the 1.
8V digital power supply.
The high power-supply rejection ratio (49dB at 100kHz) allows the MAX9509/ MAX9510 to reject the noise from the digital power supply.
The MAX9509 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 MAX9509/ MAX9510 also feature a transparent input sync-tip clamp, allowing AC-coupling of input signals with different DC biases.
The MAX9509/MAX9510 have an internal fixed gain of 8.
The input full-scale video signal is nominally 0.
25VP-P, and the output full...
