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 150
Ω
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
.
