• Manufacturer Part Number: MAX9713EVKIT
• Description: MAX9713 Evaluation Kit
• Manufacturer: MAXIM [Maxim Integrated Products]

Before beginning, the following equipment is needed:
• 15V, 1A power supply
• Audio source (i.e., CD player, cassette player)
• 8Ω/16Ω speaker
The MAX9713 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) Verify that no shunt is across jumper JU6 (differential
2) Verify shunt across pins 1-2 of jumper JU1. Install

The MAX9713 EV kit contains the MAX9713 filterless
class D amplifier IC. The EV kit operates from a 10V to
25V DC power supply and accepts a differential or sin-
gle-ended audio input source. The single-ended input
mode accepts up to 2V
mode accepts up to 4V
source is amplified to drive 6W into an 8Ω speaker.
The MAX9713 EV kit provides three sets of differential
outputs. The device outputs (OUT+/-) can be connect-
ed directly to a speaker load without any filtering.
However, a filter can be added to ease evaluation. The
filtered outputs (FOUT1+/-) require installation of filter-
ing components T1, C21, and C22. The LCR filtered
outputs (FOUT2+/-) require installation of filtering com-
ponents L4, L5, C15–C20, R2, and R3.
