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 load at VS = 24 V, or 1.5 W
(d = 10 %) into an 8 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.
