TDA3190 Datasheet - STMicroelectronics

DESCRIPTION
The TDA3190 can give an output power of 4.2 W (d = 10 %) into a 16 Ω load at VS = 24 V, or 1.5 W (d = 10 %) into an 8 Ω load at VS = 12 V. This performance,together with the FM-IF section characteristics of high sensitivity, high AM rejection and low distortion, enables the device to be used in almost every type of television receivers.
The device has no irradiation problems, hence no external screening is needed.
The TDA3190 is a pin to pin replacement of TDA1190Z.

The TDA3190 is a monolithic integrated circuit in a 16-lead dual in-line plastic package. It performs all the functions needed for the TV sound channel :
■ IF LIMITER AMPLIFIER
■ ACTIVE LOW-PASS FILTER
■ FM DETECTOR
■ DC VOLUME CONTROL
■ AF PREAMPLIFIER
■ AF OUTPUT STAGE
