Schematics of output stages
IV. Output driver
EM22300 series provide output circuits to drive speaker.Moreover, EM22309 and EM22312 provide driver
to drive piezo-buzzer directly. Two selective output current levels of VO can be selected by pin ISEL. By
connecting ISEL to V
DD
, VO outputs driving current with high level which full scale is 5mA. VO outputs
driving current with low level which full scale is 3mA if ISEL is connected to V
SS
.
