MAX9515 is an ultra-small standard-definition video filter amplifier with automatic shutdown from Texas Instruments. The device is packaged in a 1mm x 1mm UCSP with 4 bumps. The automatic shutdown circuitry eliminates the need for a shutdown control. This feature provides intelligent power management by disabling the filter and output amplifier in the absence of a video input signal and/or an output video load. At shutdown, the device only consumes 5µA. MAX9515 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 to 9MHz and typically 50dB of attenuation at 27MHz. The video input to the MAX9515 can be directly connected to the DAC output. MAX9515 has an internal fixed gain of 2V/V and expects a nominal full-scale video input signal of 1VP-P. MAX9515 is specified to operate over the -40°C to +125°C automotive temperature range.

The MAX9541/MAX9542 are quadruple-channel, 2:1 video mux amplifiers with input sync tip clamps. These devices select between two video sources and support up to four channels on each source. The MAX9541 has integrated lowpass filters that are optimized for standard-definition video signals such as composite and red, green, blue (RGB). The filters typically have ±1dB pass-band flatness out to 9.5MHz and 47dB attenuation at 27MHz. The MAX9542 has a wider bandwidth of 15MHz because it does not have integrated lowpass filters, mak-ing it suitable for not only standard-definition video sig- nals, but also video graphics array (VGA) signals with a 640 x 480 resolution at up to 85Hz refresh rate. Video signals are AC-coupled to the inputs of the MAX9541/MAX9542. The input sync-tip clamps set the internal DC level. The amplifiers have 2V/V gain, and the outputs can be DC-coupled to a 75Ω load, which is the equivalent of two video loads, or AC-coupled to a 150Ω load. Both the MAX9541/MAX9542 feature a low-power shut- down mode, in which supply current is reduced to 35µA.

The MAX9532 DirectDrive® video filter amplifier is specifically designed to work in harsh environments such as automobiles. The MAX9532 provides integrated short-to-battery protection, allowing the output of the device to survive shorts up to 18V. 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 so little noise into the video output that the picture is visibly flawless. The MAX9532 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 provides ±1dB passband flatness of 9.5MHz and 42dB attenuation at 27MHz. The input of the MAX9532 can be directly connected to the output of a video DAC. The MAX9532 also features a transparent input sync-tip clamp, allowing AC-coupling of input signals with different DC biases. The MAX9532 features an internal fixed gain of 4V/V. The input full-scale video signal is nominally 0.5VP-P, and the output full-scale video signal is nominally 2VP-P. The short-to-battery protection utilizes an internal switch in series with the amplifier output. When the MAX9532 detects that the output is short circuited to the battery voltage
