DRIVING VOLTAGE OUTPUT CIRCUIT

摘要

A circuit for outputting driving voltages is provided to enhance the speed of operation and to increase the accuracy of driving voltages generated from the circuit by preventing a variation of amplitude of positive and negative driving voltages due to offset difference. A circuit for outputting driving voltages includes amplifiers(104,105) and a source voltage converting circuit. The amplifiers amplify positive and negative input signals which are selectively inputted, and output driving voltages according to the amplification. The source voltage converting circuit converts a source voltage supplied to the amplifiers according to the polarity of the input signals. The amplifiers control selective conversions to a current source state and a current sink state according to the polarity of the input signals.
