MAX9507 - NEW! - 1.8V, DirectDrive Video Filter Amplifier With Load Detection And Dual SPST Analog Switches

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 58b positive 1.8V supply, the MAX9507 is able to drive a 2VP-P Video signal into a 150 load.
The MAX9507 provides an IC 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.
