38 / 92 page  36 m m m m mPD784020, 784021 8.7 D/A CONVERTER Two digital/analog (D/A) converter channels of voltage output type, having a resolution of 8 bits, are incorporated. A resistor string system is used for conversion. By writing the value to be subject to D/A conversion in the 8-bit D/A conversion value setting register (DACSn: n = 0, 1), the resulting analog value is output on ANOn (n = 0, 1). The range of the output voltages is determined by the voltages applied to the AVREF2 and AVREF3 pins. Because of its high output impedance, no current can be obtained from an output pin. When the load impedance is low, insert a buffer amplifier between the load and the converter. The impedance of the ANOn pin goes high while the RESET signal is low. DACSn is set to 0 after a reset is released. Fig. 8-8 Block Diagram of D/A Converter Remark n = 0, 1 8 AVREF2 R R R R AVREF3 ANOn DACEn 8 DACSn RESET Internal bus |
