1.8V DirectDrive Video Filter Amplifier with
Load Detection and Dual SPST Analog Switches
General Description
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 gener-
ate a clean, internal negative supply. Combining the
internal negative power supply with the external posi-
tive 1.8V supply, the MAX9507 is able to drive a 2V
P-P
video signal into a 150Ω load.
The MAX9507 provides an I
2
C interface for easy configu-
ration 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 dri-
ver 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/sin-
gle-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-cou-
pling of input signals with different DC biases.
The MAX9507 has an internal fixed gain of 8. The input
full-scale video signal is nominally 0.25V
P-P
, and the
output full-scale video signal is nominally 2V
P-P
.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
