DESCRIPTION

The TDA3190 can give an output power of 4.2 W

(d = 10 %) into a 16

(d = 10 %) into an 8

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.
