The LA1895M tuner IC includes a bus interface circuit and a D/A converter circuit on chip to allow all analog circuit functional block settings to be performed in software. This means that the roughly 20 adjustment points that previously required adjustment during manufacturing can be completely eliminated, thus achieving a significant rationalization of the end product manufacturing process. At the same time this also allows all analog circuit functions to be adjusted optimally for the reception conditions. Thus this IC both rationalizes end product manufacturing and provides improved performance.
