发明名称 Resistance ladder, D/A converter and A/D converter
摘要 A D/A converter arranged to improve the resolution by changing the number of resistors to be interposed between a resistance ladder, from which a divided voltage between positive and negative voltage sources is taken out, and the positive and negative voltage sources while maintaining the total resistance value at a constant value, in which the resistance value of the resistor to be interposed between the resistance ladder and the positive and negative voltage sources is selected to uniformly lower the divided voltage which is taken by the resistance ladder by a level corresponding to +E,fra 1/2+EE LSB to perform +E,fra 1/2+EE LSB correction.
