A one chip solution reduces the package size required and increases the reliability. Resolution Set by User. Two control pins are used to select the resolution of the AD2S80A to be 10, 12, 14 or 16 bits allowing the user to use the AD2S80A with the optimum resolution for each application. Ratiometric Tracking Conversion. Conversion technique provides continuous output position data without conversion delay and is insensitive to absolute signal……
