19-1028; Rev 0; 11/07 KIT ATION EVALU E L B A AVAIL 1.8V DirectDrive Video Filter Amplifier with Load Detection and Dual SPST Analog Switches www.datasheet4u.com 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 The MAX9507 amplifies and filters standard-definition video signals and only consumes 5.8mW quiescent power and 11.7mW average power. 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 ...
