TDA1190

The TDA1190 is designed as 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 and AF output stage. It can give an output power of 4.2W (d=10%) into a 16ohms load at Vs=24V, or 1.5W (d=10%) into an 8 load at Vs=12V. This performance, toghter 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.

Some absolute maximum ratings TDA1190 have been concluded into several points as follow. (1)Its supply voltage pin 10 would be 28V. (2)Its input signal voltage pin 1 would be 1V. (3)Its output peak current non-repetitive would be 2A. (4)Its output peak current repetitive would be 1.5A. (5)Its power dissipation at Ttab=90°C would be 5W and it would be 1W at Tamb=80°C free air. (6)Its storage and junction temperature range would be from -40°C to 150°C. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics TDA1190 are concluded as follow. (1)Its thermal resistance junction-tab would be max 12°C/W. (2)Its thermal resistance junction-ambient would be 70°C/W. (3)Its supply voltage pin 10 would be min 9V and max 28V. (4)Its quiescent output voltage pin 9 would be min 11V and typ 12V and max 13V at Vs=24V and would be min 5.5V and typ 6V and max 6.5V at Vs=12V. (5)Its quiescent drain current would be typ 22mA and max 35mA at Vs=24V and it would be typ 19mA and max 31mA at Vs=12V. (6)Its output power would be typ 4.2W at Vs=24V and would be typ 1.5W at Vs=12V. And so on.
