Abstract:
A successive approximation type A-to-D converter includes a cyclic D-to-A converter (11), a comparator (12) for comparing an analog value with an output value of the D-to-A converter (11), and memory means (13) for sequentially storing an output value of the comparator (12) and supplying the stored value to the D-to-A converter (11) in a reverse order.
