MAX9597 pdf datasheet (Low-Pow

The MAX9597 single SCART interface routes audio and
video signals between a set-top box decoder chip and
an external SCART connector under I2C control.
Operating from a 3.3V supply and a 12V supply, the
MAX9597 consumes 53mW during quiescent operation
and 254mW during average operation when driving
typical signals into typical loads.
The MAX9597 audio section contains left and right audio
paths with an independent operational amplifier at the
inputs. The DirectDrive® output amplifiers create a
2VRMS full-scale audio signal biased around ground,
eliminating the need for bulky output capacitors and
reducing click-and-pop noise. The zero-cross detection
circuitry also further reduces clicks and pops by
enabling audio sources to switch only during a zerocrossing.
The MAX9597 video section contains 4 channels of
video filter amplifiers. The standard-definition video signals
from the set-top box decoder chip are lowpass filtered
to remove out-of-bandwidth artifacts. The
MAX9597 also supports slow-switching and fast-switching
signals.
The MAX9597 is available in a compact 28-pin thin
QFN package and is specified over the 0°C to +70°C
commercial temperature range.
