Part Details:

19-0727; Rev 1; 4/07 EVALUATION KIT AVAILABLE 1.8V, Ultra-Low Power, DirectDrive Video Filter Amplifiers MAX9509/MAX9510 General Description Features Operating from a 1.8V single power supply, the MAX9509/ o 5.8mW Quiescent Power Consumption MAX9510 amplify standard-definition video signals andonly consume 5.8mW quiescent power and 11.7mW o 11.7mW Average Power Consumption average power. The MAX9509/MAX9510 leverage o 1.8V or 2.5V Single-Supply Operation Maxim s DirectDriveTM technology to generate a clean,internal negative supply. Combining the internal nega- o Reconstruction Filter with 8.1MHz Passband and tive power supply with the external positive 1.8V sup- 46dB Attenuation at 27MHz (MAX9509) ply, the MAX9509/MAX9510 are able to drive a 2VP-P o DirectDrive Sets Video Output Black Level near video signal into a 150 load. Ground Besides increasing the output voltage range, Maxim s o DC-Coupled Input/Output DirectDrive technology eliminates large output-couplingcapacitors and sets the output video black level near o Transparent Input Sync-Tip Clamp ground. DirectDrive requires an integrated charge pump o Internal Fixed Gain of 8 and an internal linear regulator to create a clean negativepower supply so that the amplifier can pull the sync o 10nA Shutdown Supply Current below ground. The charge pump injects little noise into Applications the video output, making the picture visibly flawless. The MAX9509/MAX9510 are designed to operate from the Digital Still Cameras Mobile Phones 1.8V digital power supply. The high power-supply rejec- (DSC) Security/CCTV tion ratio (49dB at 100kHz) allows the MAX9509/ Digital Video Cameras Cameras MAX9510 to reject the noise from the digital power supply. (DVC) Automotive The MAX9509 features an internal reconstruction filter Portable Media Players Applications that smoothes the steps and reduces the spikes on the (PMP) video signal from the video digital-to-analog converter(DAC). The reconstruction filter typically has ±1dB Block Diagram passband flatness of 8.1MHz and 46dB attenuation at27MHz. The large-signal, ±1dB passband flatness ofthe MAX9510 video amplifier is typically 8.4MHz, andthe large signal -3dB frequency is typically 11.4MHz. IN AV =
