MAX9509/MAX9510 19-0727 Rev 1 4/07 1.8V, Ultra-Low Power, DirectDrive Video Filter Amplifiers General Description Features Operating from a 1.8V single power supply, the MAX9509/ 5.8mW Quiescent Power Consumption MAX9510 amplify standard-definition video signals and 11.7mW Average Power Consumption only consume 5.8mW quiescent power and 11.7mW average power. The MAX9509/MAX9510 leverage 1.8V or 2.5V Single-Supply Operation Maxims DirectDrive technology to generate a clean, Reconstruction Filter with 8.1MHz Passband and internal negative supply. Combining the internal nega- 46dB Attenuation at 27MHz (MAX9509) tive power supply with the external positive 1.8V sup- ply, the MAX9509/MAX9510 are able to drive a 2V P-P DirectDrive Sets Video Output Black Level near video signal into a 150 load. Ground Besides increasing the output voltage range, Maxims DC-Coupled Input/Output DirectDrive technology eliminates large output-coupling capacitors and sets the output video black level near Transparent Input Sync-Tip Clamp ground. DirectDrive requires an integrated charge pump Internal Fixed Gain of 8 and an internal linear regulator to create a clean negative 10nA Shutdown Supply Current power supply so that the amplifier can pull the sync 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 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. IN OUT A = V LPF* 8V/V The input of the MAX9509/MAX9510 can be directly TRANSPARENT connected to the output of a video DAC. The MAX9509/ CLAMP 250mV VIDEO 2V VIDEO P-P P-P MAX9510 also feature a transparent input sync-tip LINEAR clamp, allowing AC-coupling of input signals with differ- REGULATOR 0V ent DC biases. The MAX9509/MAX9510 have an inter- nal fixed gain of 8. The input full-scale video signal is SHDN MAX9509 CHARGE nominally 0.25V , and the output full-scale video sig- P-P MAX9510 PUMP nal is nominally 2V . The devices operate from a 1.8V P-P or 2.5V single supply and feature a 10nA low-power *FOR MAX9509 shutdown mode.
