Product Details

Description



Features:

· Eight (TDA2555) or five (TDA2557) stage limiting amplifier
· Quadrature demodulator for FM detection
· De-emphasis stage
· Output amplifier
· Mute function for each FM demodulator


Specifications

Supply voltage (pins 13 and 15)                                           VP max. 13,2 V
Total power dissipation                                                   Ptot max. 400 mW
Storage temperature range                                           Tstg -40 to + 150
Operating ambient temperature                                        Tamb 0 to + 70


Description

The circuits incorporate two FM demodulator systems to perform the demodulator functions required in a dual sound carrier TV system for demodulating the sound carriers.

The difference between TDA2555 and TDA2557 is the number of stages of the limiting amplifier.
