Introduction

The TSH512 is a 0.4- to 11-MHz dual FM transmitter. Access pins to each section give high versatility and allow for several different applications: stereo headphone, multimedia headset, audio sub-carrier generator. The TSH512 integrates in a single chip low-noise audio preamplifiers with ALC (automatic level control), frequency-modulated oscillators, and linear output buffers to drive the external transistors. The sinusoidal carriers facilitate the filtering and allow high performance audio transmission. The VOX (voice operated transmit) circuitry disables the output buffer when there is no audio signal to save battery power. For MONO applications, the STANDBY pin enables one transmitter only, reducing the supply current. The TSH512 forms a chipset with the dual receiver TSH511.
