4. Important Notes on Use
The internal amplifier has an overheating protection circuit. Once the temperature of the
output IC exceeds the threshold value the output will be turned off. If the protection has
been activated ensure to turn off the power supply and review the load on the product
or ambient temperature.
* The overheat protection will not recover until the power supply has been cut off.
Also has an overcurrent protection circuit. The protection circuit will be active while the
rated output current is flowing. If the protection does get activated ensure to review the
load on the product and signals.
Switching the output switch from off to on while the output level is high may activate the
overcurrent protection circuit and the output may not therefore be correct. Ensure to
turn the output switch on first and then increase the signal voltage.
