Abstract
PURPOSE: To obtain required control precision without increasing conversion by setting the center value of an analog output, equivalent to an input including the smallest digital value of the bit constitution of less than a fixed number of digits, lower than fixed normal value by the maximum error value.
CONSTITUTION: According to input digital n-bit information, switches S1 to Sn are turned ON selectively to supply constant currents from constant-current supplied I1 to In to the constant-resistance network, so that an analog voltage equivalent to the input will be developed at the output terminal. To this circuit, center value Q of the output analog value equivalent to input "10000" including the smallest value of digital values of four bits, for example, it set lower by at least the maximum relative error 2Δ0 than normal-value-M point obtained by adding unit variation Δ0 to an analog vlaue equivalent to input value "01111", smaller by one than "10000", including the maximum value "11111" of four-bit constitution. For the purpose, the value of constant current supply I5 for the 5th bit is set lower by 2Δ0 than the value of I1 to I4. Consequently, even if the maximum error occurs in the positive direction, stable operation can be obtained and required precision can also be obtained economically.
