GENERAL DESCRIPTION
FEATURES
o 1.8V or 2.5V Single-Supply Operation o Low Power Consumption (5.8mW Quiescent, 11.7mW Average) o Video Load Detection o DirectDrive Sets Video Output Black Level Near Ground o o o Dual SPST Analog Switches Transparent Input Sync-Tip Clamp I2C Control MAX9507 Combining the internal negative power supply with the external positive 1.8V supply, the MAX9507 is able to drive a 2VP-P video signal into a 150Ω load. The MAX9507 can detect, report, and act upon the change of a video load. This feature helps reduce overall power consumption by allowing the system to turn on the video encoder and driver only when a video load is connected to the MAX9507. With a high power-supply rejection ratio (47dB at 100kHz), the MAX9507 can be powered directly from a 1.8V digital supply. The two integrated single-pole/single-throw (SPST) analog switches are ideal for routing audio, video, or digital signals. The input of the MAX9507 can be directly connected to the output of a video DAC.
