Quick Start List for Stand-Alone

-Evaluation Module Preparations

6)To have the module amplifier IC enter the shutdown mode when the module mute control input is activated, set shutdown jumper S1 to ON. To have the amplifier IC only mute when the module mute control input is activated, set shutdown jumper S1 to OFF.

7)To select the line inputs, set input select jumper S3 to OFF. To select the headphone inputs, set input select jumper S3 to ON.

8)To allow the module SE/BTL control input to switch the amplifier IC between single ended (SE) and bridge-tied load (BTL) output modes, set output mode jumper S4 to OFF. To keep the module amplifier IC in the single-ended output mode regardless of the control input state, set jumper S4 to ON.

9)Set VDD bridge jumper S5 to ON to connect the RVDD and LVDD module power input pins together, or to OFF to keep the two power inputs isolated

on board

10)To automatically select the headphone inputs when the single-ended output mode is selected by the module SE/BTL control input, set autosense control jumper S6 to ON. To isolate the amplifier IC input select pin from the module output mode select control input, set autosense control jumper S6 to OFF.

11)Set junction temperature measurement jumper S8 to OFF for normal operation

-Control Inputs

12)Connect control lines to the various module control input pins as needed:

a)HP/L*: A high selects the headphone input pins; a low or float selects the line input pins.

b)SE/BTL*: A high selects the single-ended output mode; a low or float selects the bridge-tied load output mode.

c)MUTE: A high mutes the amplifier IC on the module; a low or float allows normal operation.

-Power-up

13)Verify correct voltage and input polarity and set the external power supply to ON.

The EVM should begin operation.

14) Adjust the signal source level as needed.
