LINEAR INTEGRATED CIRCUIT
COMPLETE TV SOUND CHANNEL
The TDA 1190Z is a monolithic integrated circuit in a 12-lead quad 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
The TDA 1190Z can give an output power of 4.2W (d = 10%) into a 160 load at Vs = 24V, or 1.5W (d = 10%) into an 80 load at Vs = 12V. This performance, together with the FM-IF section charac-
teristics 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.
