Abstract: In an analog-to-digital converter circuit of pipeline type configured by cascade-connecting a plurality of analog-to-digital conversion blocks, at least analog-to-digital conversion blocks at an initial stage excluding an analog-to-digital conversion block at a final stage have each a function as an amplifier and are switched by a control signal inputted externally so that the analog-to-digital conversion blocks each operates as the amplifier. When the analog-to-digital conversion blocks each having the function as the amplifier are each operated as the amplifier by the control signal, a digital signal is generated by using data outputted from an analog-to-digital conversion block provided subsequent to the analog-to-digital conversion blocks operating as the amplifiers.

Abstract: In an analog-to-digital conversion circuit, the gain of an operational amplification circuit in each of first- to third-stage circuits is two. The reference voltage range of a sub-A/D converter in each of the stages of circuits is set to one-half the reference voltage range of a D/A converter, so that the output voltage range of the D/A converter coincides with the output voltage range of the operational amplification circuit. When the voltage range of the analog input signal is VINp-p, the full-scale range of the sub-A/D converter is switched to VINp-p, and the gain of the operational amplification circuit is one. When the voltage range of the analog input signal is VINp-p/2, the full-scale range of the sub-A/D converter is switched to VINp-p/2, and the gain of the operational amplification circuit is two.
