Schematics of output stages
IV. Output driver
EM22203/EM22206 provide output circuits to drive speaker. Two selective output current levels of VO can
be selected by pin ISEL. By connecting ISEL to V
, VO outputs driving current with high level which full
scale is 5mA. Vo outputs driving current with low level wich full scale is 3mA if ISEL is connected to V
