TDA3190

COMPLETE TV SOUND CHANNEL

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

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 char-

acteristics 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.
