GENERAL DESCRIPTION
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.
