Working Principles

The DAC08EP utilizes a binary-weighted resistor ladder network to convert digital input data into an analog output current. The digital input is applied to the 8-bit data bus, and the control inputs (WR, CS, RD) determine the conversion process. The internal reference voltage or an external reference voltage is used to set the output voltage range. The analog output current is then converted into a voltage using an external resistor.
