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.
