TSH511 Dual FM receiver with audio amplifiers

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.

Featuring high input sensitivity and high input dynamic range, each receiver integrates an RF front-end LNA, an intermediate amplifier with 2 external filters, a voltage limiter, a quadrature FM demodulator, and finally an audio buffer.

The integrated audio buffers are able to directly drive a 16-ohm headphone with 20mW. A squelch circuit mutes both audio amplifiers.

Access pins to each section makes the TSH511 suited for a wide field of applications.

For mono applications, the standby pin enables one receiver only, reducing the supply current.

The TSH511 forms a chipset with the dual transmitter TSH512.
