Digitally controlled attenuator uses DG201 quad analog switch as input ladder attenuator switches for A/D converter. Switches are controlled by digital logic that detects overrange and underrange information from A/D converter and closes appropriate attenuator path. Circuit is suitable for Siliconix LD110/111 or LD111/114 A/D converter，— Analog Switches and Their Applications, Siliconix、Santa Clara、CA、1976, p 6-28.
