Preliminary Technical Data
SSM2301
EVALUATION BOARD INFORMATION
INTRODUCTION
The SSM2301 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 SSM2301
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 SSM2301
evaluation board.
Specification
2.5 V to 5.0 V
1.5 A
1.4 W
8 Ω
Power and Ground
1.
Set the power supply voltage between 2.5 V and 5.0 V When
connecting the power supply to the SSM2301 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 IN± and IN±.
3.
Connect the speakers to Outputs OUT± and OUT±.
Gain Control
The gain select header controls the gain setting of the SSM2301.
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 SSM2301 gain using external resistors
at the input. To set a gain lower than 12 dB refer to Figure 21
and Figure 22 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)]
To set a gain lower than 6 dB refer to Figure 23 and Figure 24
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 SSM2301. The shutdown pin on the SSM2301 is active low,
meaning that a low voltage (GND) on this pin places the SSM2301
into shutdown mode.
1.
Select jumper to 1-2 position. Shutdown pulled to V
DD
.
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 J2 and J3.
2.
For differential input configuration without input capacitors
place a jumper on J2 and J3.
