INTEGRATED CIRCUITS DATA SHEET TBA120U Sound I.F. amplifier/demodulator for TV Product specification File under Integrated Circuits, IC02 March 1986 Philips Semiconductors Product specification Sound I.F. amplifier/demodulator for TV GENERAL DESCRIPTION TBA120U The TBA120U is an i.f. amplifier with a symmetrical FM demodulator and an a.f. amplifier with adjustable output voltage. The a.f. amplifier is also provided with an output for volume control and an input for VCR operation. The input and output of the TBA120U are especially designed for LC-circuits, but the input can also be used with a ceramic filter. QUICK REFERENCE DATA Supply voltage (pin 11) Supply current I.F. voltage gain at f = 5,5 MHz Input voltage starting limiting AM suppression at f = ± 50 kHz A.F. output voltage adjustment range (pin 8) A.F. output voltage at f = ± 50 KHz (r.m.s. value) at pin 8 at pin 12 PACKAGE OUTLINE 14-lead DIL; plastic (SOT27); SOT27-1; 1996 November 19.
