Application information
This section gives application information for some typical applications.
4.1
Infrared stereo transmitter application (stereo headphones)
In this application, shown in Figure 21, the hi-fi stereo audio is amplified and level regulated
by ALC. The carrier of each transmitter TX1 or TX2 of the TSH512 is modulated in FM and
buffered to drive the LED.
Figure 21.
Hi-fi stereo headphone block diagram
The audio signals are transmitted on the left and the right channels using 2.8- and 2.3-MHz
carriers. The VOX activates the TX1 transmitter when the audio signal is present
