The TSH511 is a 0.4 to 11MHz dual FM receiver. This circuit offers the functions needed for a highly sensitive infrared hi-fi stereo receiver.
The TSH511 is a dual FM receiver designed for high-sensitivity infrared hi-fi stereo receivers and stereo sub-carrier demodulation. It integrates an RF front-end LNA, an intermediate amplifier, a voltage limiter, a quadrature FM demodulator, and audio buffers capable of driving a 16-ohm headphone with 20mW. The device supports carrier frequencies from 0.4MHz to 11MHz and offers flexibility through access pins for each section.
