MAX9776 Evaluation Kit

Evluates:MAX976

Connect the mono loudspeaker between the FOUT+

and FOUT- pads.

connected between the VDD and GND pads. All other

support devices are powered from the USB supply.

Class D and EMI Filtering

Two types of filters are available on the Class D output.

One filter is an LCR filter intended to be used to connect

the Class D output to an audio analyzer or oscilloscope.

The output of this filter is between FOUT+ and FOUT-.

Hardware Shutdown Control

Jumper JU6 controls the hardware shutdown function

of the MAX9776 EV kit. This will shut down the entire

MAX9776 and reset all the registers to their power-on

defaults. See Table 1 for shutdown shunt positions.

The second filter is an EMI filter consisting of ferrite

beads and capacitors. The ferrite beads and capaci-

tors are included in the MAX9776 EV kit’s shipping box.

Install the EMI filter by removing the 0Ω resistors from

pads FB7 and FB8 and installing the ferrite beads. Also

install the included capacitors on pads C36 and C37.

Be sure to remove inductors L1 and L2 before EMI test-

ing is started. Connect the load across test points

OUT+ and OUT-.

User-Supplied I²C Interface

MAX9776 I²C Address

The MAX9776 is an I²C/SMBus slave device that can

only be written to. The slave address is fixed to

1001101x in binary.

To use the MAX9776 EV kit with a user-supplied I²C

interface, remove the shunts on jumper JU4 and JU5.

Connect SDA, SCL, and GND lines from the user-

supplied I²C interface to the corresponding pads on

the MAX9776 EV kit board. Depending on the configu-

ration of the user-supplied I²C interface, it may be nec-

essary to install I²C pullup resistors R1 and R2.

Power Supply

The MAX9776 EV kit board is powered from both a user-

supplied +2.7V to +5.5V supply, and the +5V USB sup-

ply. U1 is powered by a user-provided DC power supply
