What to check
First check the ”option check box” on the demoboard for the IC type and application.
Connecting the power: check the polarity of the power supply, adjust current limit to 400mA. Although the
demoboard is protected against over voltage and wrong polarity, the supply current has to be limited.
Check if solder jumper J1 & J2 are configured as follows:
TZA3014:
default the mute function is used, R11 has to be connected to GND using J1. Solder jumper J2 is left
open (S1-1 is switched off and S3 must be switched on).
TZA3019A:
both solder jumpers J1 & J2 are left open.
TZA3019B:
default the “auto switch” function is used, R11 has to be connected to GND using J1. Solder jumper
J2 is left open (S1-1 and S1-2 are switched off).
TZA3019C:
Default the LEDs, D3 and D1, are used to observe the LOS outputs. The LEDs have to be
connected to GND using J1 and J2.
