Note: Indicate that you are using the MAX9736A or MAX9736B when contacting these component suppliers.
Quick Start
5) Install a shunt across jumper JU5 (MOD = high,
filterless modulation scheme).

Required Equipment
8V to 28V, 5A DC power supply
Audio source with volume control (e.g., CD player, etc.)
Two speakers
6) Connect the first speaker across the FOUTL- and
FOUTL+ PCB binding posts.
7) Connect the second speaker across the FOUTR-
and FOUTR+ PCB binding posts.
Procedures
The MAX9736A EV kit is fully assembled and tested.
Follow the steps below to verify board operation.
Caution: Do not turn on the power supply until all
connections are completed.
1) Install a shunt across pins 1-2 of jumper JU1 (DVDD
= 5V).
2) Install a shunt across jumper JU2 ( SHDN = high, EV
kit enabled).
3) Install a shunt across jumper JU3 (REGEN = high,
internal regulator enabled).
4) Install a shunt across jumper JU4 ( MUTE = high,
output enabled).
8) Connect the positive terminal of the power supply to
the VDD binding post and the power-supply ground
terminal to the PGND binding post.
9) Connect the left output terminal of the audio source
to the LIN RCA phono jack.
10) Connect the right output terminal of the audio
source to the RIN RCA phono jack.
11) Turn on the audio source at minimum volume.
12) Turn on the power supply.
13) Gradually increase the audio source volume until
audio is heard through the loud speakers.
