SSM2304
Preliminary Technical Data
EVALUATION BOARD INFORMATION
INTRODUCTION
The SSM2304 audio power amplifier is a complete low power,
Class-D, stereo audio amplifier capable of delivering 2.8 W/channel
into 4 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 SSM2304
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 SSM2304
evaluation board.
Specification
2.5 V to 5.0 V
1.5 A
2 W
4 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 SSM2304 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±.
External Gain Settings
It is possible to adjust the SSM2304 gain lower than 18 dB using
external resistors at the input, refer to
Error! Reference source
not found.
6 and
Error! Reference source not found.
7 on the
product data sheet for proper circuit configuration. For external
gain configuration, use the following formula:
External Gain Settings
= 300k/(37.5k+Rext)
Shutdown Control
The shutdown select header controls the shutdown function of
the SSM2304. The shutdown pin on the SSM2304 is active low,
meaning that a low voltage (GND) on this pin places the SSM2304
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 JP8, JP9, JP10, and JP11.
2.
For differential input configuration without input capacitors
place a jumper on JP8, JP9, JP10, and JP11.
