The MAX9507 leverages Maxim’s DirectDrive™ technology to generate a clean, internal negative supply. 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 provides an I2C interface for easy configuration and access to the load status. 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. The MAX9507 also features a transparent input sync-tip clamp, allowing AC-coupling of input signals with different DC biases. The MAX9507 has an internal fixed gain of 8. The input full-scale video signal is nominally 0.25VP-P, and the output full-scale video signal is nominally 2VP-P.
