PACKAGE
DESCRIPTION
The TSH511 is a 0.4 to 11 MHz dual FM receiver.
This circuit offers the functions needed for a highly
sensitive infrared HiFi STEREO receiver.
Featuring high input sensitivity and high input dy-
namic range, each receiver integrates a RF
front-end LNA, an intermediate amplifier with 2 ex-
ternal filters, a voltage limiter, a quadrature FM de-
modulator, and finally an audio buffer.
The integrated audio buffers are able to drive di-
rectly a 16 ohms 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 en-
ables one receiver only, reducing the supply cur-
rent.
The TSH511 forms a chipset with the dual trans-
mitter TSH512.
