TSH511

MULTIMEDIA APPLICATION: HEADSET SIDE

The TSH511 receives the HiFi stereo sound from the computer through 2.3 and 2.8 MHz stereo infrared

carriers. The access pins to the RF amplifiers allow the use of a 1.7 MHz reject filter to cancel the trans-

mitted signal of the microphone. The wide supply range (2.3 to 5.5 V) allows battery operation.

TSH511 & 512 supply:

MULTIMEDIA APPLICATION: COMPUTER SIDE

In multimedia application, the TSH511 receives the voice of the user through the 1.7 MHz infrared carrier.

The standby pins can disable the unused receiver and audio amplifier to reduce the supply current.
