ABSTRACT:
The present invention aims to provide a linear type digital-to-analog converter which has a great freedom of design and then is not affected by a parasitic capacity. The linear type digital-to-analog converter comprises a lower digital-to-analog converting portion having a plurality of lower serial circuits connected in a ladder manner between a lower output line, and an earthed line and a reference voltage line, the lower serial circuit comprising a lower capacitor and a lower transfer type switch, and a weighted second capacitor connected between the lower output line and the earthed line, an upper digital-to-analog converting portion having a plurality of upper serial circuits connected in a ladder manner between an upper output line, and the earthed line and the reference voltage line, the upper serial circuit comprising an upper capacitor and an upper transfer type switch, and the lower output line and the upper output line are connected through a coupling capacitor. A buffer amplifier is disposed between the lower output line and the coupling capacitor.
