The 4193 circuit uses a two stage subranging technique. First the input is approximated to seven bits. Then the seven bit word is applied to an accurate 12 bit DAC. The output of the DAC and the input are subtracted and amplified to create an error signal which is then digitized to seven bits. Combining the first and second seven bit word results in a 12 bit accurate result. See Figure l, Pin Connections and Block Diagram.
