Description

The MAX9680 high-speed amplifier and filter is optimized for portable video applications. It is specifically designed to be compatible with the video encoders embedded in application processors with 0.4VP-P video output. The input common-mode range includes GND, which allows a video DAC (digital-to-analog converter) to be DC-coupled to the MAX9680.

The output swings within 2mV of GND and 20mV to VDD with a standard back-terminated video load (150Ω). An internal level shift circuit prevents the output from saturating with 0V input, thus preventing sync-pulse clipping in common video circuits. Therefore, the MAX9680 is ideally suited for DC-coupling to the video load.

The MAX9680 has been optimized for space-sensitive applications by integrating internal gain setting resistors (G = 5.2V/V) and a 2-pole video-DAC reconstruction filter.

In shutdown mode, the quiescent current is reduced to less than 0.4µA, dramatically reducing power consumption and prolonging battery life. The MAX9680 is available in the tiny 2mm x 2.1mm, 6-pin, SC70 package.
