Digital integrated amplifier which carries a digital analog converter
It was selected carefully from device"A version" of the Philips Marantz group by the D-A-conversion part, TDA1541 A-S1 LSI on which the crown multiple asynchronously communicating hosts proving the best was stamped is adopted as it, and the tone quality excellent in especially the reproductivity in a low is realized.
The power amplifier part has the simple composition that an input signal is direct fed from a volume, and the first rank is a differential amplification of a cascode interconnection, and has secured sufficient gain (gain) with the combination of FET and a bipolar transistor.
The output stage has adopted Power-MOS FET which is a triple push pull stream composition and is an element of the power amplification for audios. Moreover, two kinds of operation methods, a pure Class-A operation and AB class operation, can be chosen by switchpoint switching.
