Circuit device, electronic apparatus, and moving object

A circuit device comprising:

• a multiplexer that selects an input signal from first to n-th input signals (n is an integer greater than or equal to 2) inputted to first to n-th input nodes in a time division manner and outputs the selected input signal to an output node;
• an A/D conversion circuit that receives the first to n-th input signals outputted from the multiplexer to the output node in a time division manner and A/D-converts the received first to n-th input signals in a time division manner;
• and
• a buffer circuit provided between an i-th input node (i is an integer greater than or equal to 1 but smaller than or equal to n) among the first to n-th input nodes and the output node of the multiplexer,
• wherein the buffer circuit buffers the i-th input signal among the first to n-th input signals and outputs the buffered signal to the output node of the multiplexer in a first period,
• the multiplexer selects the i-th input signal and outputs the selected signal to the output node in a second period, and
• end timing of the second period comes after end timing of the first period.
