PURPOSE: An inkjet-head driving device is provided to prevent a multi-channel switch element from becoming damaged due to high-voltage pulse when the on/off control data of each channel is loaded. CONSTITUTION: An inkjet-head driving device comprises an amplifying terminal(140), a multi-channel switch element(150), a state recognizing unit(170), and a control unit(120). The amplifying terminal amplifies driving signals input from a DAC(130). The multi-channel switch element comprises a plurality of channels. The multi-channel switch element applies the amplified driving signals to an actuator(160) connected each channel depending on the on/off control data of channels. The state recognizing unit recognizes the output state of the amplifying terminal and outputs information on an output state.
