TSH512 General Description

The TSH512 is a 0.4 to 11 MHz dual FM transmitter. Access pins to each section give a high versatility and allow several applications: stereo headphone, multimedia headset, audio sub-carrier generator.

The TSH512 integrates in one chip: Low-noise audio preamplifiers with ALC (Automatic Level Control), frequency modulated oscillators, and linear output buffers to drive external transistors.

The sinusoidal carriers facilitates the filtering and allows high performance audio transmission.

The VOX (Voice Operated Transmit) circuitry disables the output buffer when there is no audio to save battery power.

For MONO applications, the STAND-BY pin enables one transmitter only, reducing the supply current.

The TSH512 forms a chipset with the dual receiver TSH511.
