In the case where the distance between the TS2012 output and the speaker terminals is too
long, it is possible to have low frequency EMI issues due to the fact that the typical operating
frequency is 280 kHz. In this configuration, it is necessary to use the output filter
represented in Figure 1 on page 5 as close as possible to the TS2012.

Short-circuit protection
The TS2012 includes output short-circuit protection. This protection prevents the device
from being damaged in case of fault conditions on the amplifier outputs.
When a channel is in operating mode and a short-circuit occurs between two outputs of the
channel or between an output and ground, the short-circuit protection detects this situation
and puts the appropriate channel into standby. To put the channel back into operating mode,
is needed to put standby pin of the channel to logical LO and after again to logical HI and
wake-up the channel.
4.11
Thermal shutdown
The TS2012 device has an internal thermal shutdown protection in the event of extreme
temperatures to protect the device from overheating. Thermal shutdown is active when the
device reaches 150°C. When the temperature decreases to safe levels, the circuit switches
back to normal operation.
