Stand-Alone Operational
Amplifier Applications
The input amplifier of the audio section can be utilized
for stand-alone operational amplifier applications by
configuring ENC_INR+ and ENC_INL+ input as the
noninverting input, ENC_INR- and ENC_INL- input as
the
inverting
input
and
ENC_INROUT
and
ENC_INLOUT output as the output of the stand-alone
operational amplifier. The gain-bandwidth product of
the amplifier is 7MHz (typ).
Applications That Do Not Need
the Slow-Switch Signal
V12 should be left unconnected if the MAX9597 is used
in an application that does not require the slow-
switch output signal. See Figure 18.
Power-Supply Bypassing
The MAX9597 features single 3.3V and 12V supply
operation and requires no negative supply. The 12V
supply V12 is for the SCART slow-switching function.
For pin V12, place a 0.1F bypass capacitor as close to
it as possible. Connect VAUD to 3.3V and bypass with a
10F electrolytic capacitor in parallel with a 0.1F
ceramic capacitor to audio ground. Bypass VVID to
GND with a 0.1F ceramic capacitor.
Using a Digital Supply
The MAX9597 was designed to operate from noisy digi-
tal supplies. The high video PSRR (47dB at 100kHz)
allows the MAX9597 to reject the noise from the digital
power supplies (see the
Typical Operating Character-
istics). If the digital power supply is very noisy and
stripes appear on the television screen, increase the
supply bypass capacitance. An additional, smaller
capacitor in parallel with the main bypass capacitor
can reduce digital supply noise because the smaller
capacitor has lower equivalent series resistance (ESR)
and equivalent series inductance (ESL).
Layout and Grounding
For optimal performance, use controlled-impedance
traces for video signal paths and place input termina-
tion resistors and output back-termination resistors
close to the MAX9597. Avoid routing video traces par-
allel to high-speed data lines.
