EVALUATION BOARD INFORMATION
INTRODUCTION
The SSM2302 audio power amplifier is a complete low power,
Class-D, stereo audio amplifier capable of delivering 1.4 W/channel
into 8 Ω load. In addition to the minimal parts required for the
application circuit, measurement filters are provided on the
evaluation board so that conventional audio measurements can
be made without additional components.
This section provides an overview of Analog Devices SSM2302
evaluation board. It includes a brief description of the board as
well as a list of the board specifications.

OPERATION
Use the following steps when operating the SSM2302
evaluation board.
Power and Ground
1.
Set the power supply voltage between 2.5 V and 5.0 V. When
connecting the power supply to the SSM2302 evaluation
board, make sure to attach the ground connection to the
GND header pin first and then connect the positive supply
to the VDD header pin.
Inputs and Outputs
1.
Ensure that the audio source is set to the minimum level.
2.
Connect the audio source to Inputs INL± and INR±.
3.
Connect the speakers to Outputs OUTL± and OUTR±.
Gain Control
The gain select header controls the gain setting of the SSM2302.
1.
Select jumper to LG for 6 dB gain.
2.
Select jumper to HG for 12 dB gain.
External Gain Settings
It is possible to adjust the SSM2302 gain using external resistors
at the input. To set a gain lower than 12 dB refer to Figure 22
and Figure 23 on the product data sheet for proper circuit con-
figuration. For external gain configuration from a fixed 12 dB
gain, use the following formula:
External Gain Settings = 20 log[4/(1 + R/150 kΩ)]
on the product data sheet for proper circuit configuration. For
external gain configuration from a fixed 6 dB gain, use the
following formula:
External Gain Settings = 20 log[2/(1 + R/150 kΩ)]
Shutdown Control
The shutdown select header controls the shutdown function of
the SSM2302. The shutdown pin on the SSM2302 is active low,
meaning that a low voltage (GND) on this pin places the SSM2302
into shutdown mode.
1.
Select jumper to 1-2 position. Shutdown pulled to VDD.
2.
Select jumper to 2-3 position. Shutdown pulled to GND.
Input Configurations
1.
For differential input configuration with input capacitors
do not place a jumper on JP8, JP9, JP10, and JP11.
2.
For differential input configuration without input capacitors
place a jumper on JP8, JP9, JP10, and JP11.
