Part Details:

19-3675; Rev 1; 8/05 DirectDrive Video Amplifier with Reconstruction Filter and Analog Switch MAX9505 General Description Features The MAX9505 filters and amplifies standard-definition DC-Coupled Output video signals. Maxim s DirectDriveTM technology elimi-nates large output-coupling capacitors and sets the Direct Connection to Video DAC video black level to ground. An internal reconstruction Video Output Black Level Set to Ground filter smoothes the steps and reduces the spikes on thevideo signal from the video digital-to-analog converter Video Reconstruction Filter with 50dB (DAC). The input of the MAX9505 can be directly con- Attenuation at 27MHz nected to the output of a DAC. The MAX9505 provides 6dB Gain a compact, integrated, and low-power solution. 1.7 R The reconstruction filter typically has 3dB attenuation at ON Analog Switch 9MHz and 50dB attenuation at 27MHz, and ±1dB pass- 10nA Shutdown Supply Current band flatness to 5.5MHz. 2.7V to 3.6V Single-Supply Operation Maxim s DirectDrive uses an integrated charge pumpand a linear regulator to create a negative power supplyto drive the sync below ground. The charge pump injectsso little noise into the video output that the picture is visi-bly flawless. Ordering Information The MAX9505 features an internal 1.7 analog switchthat interfaces with a 4-pole multimedia jack. This PIN- PART* PKG CODE TOP MARK switch allows one of the poles to be set as a video PACKAGE input, a video output, or a microphone input.
