8 Bit DAC DAC0808

The 8 Bit DAC DAC0808 is an 8-bit multiplying digital-to-analog converter IC. It turns an 8-bit value from a microcontroller, counter or logic circuit into an output current that is proportional to that value and to a reference current, settling in about 150 ns. With an external op-amp, the current becomes an analog voltage for waveform generation, control circuits and lab experiments.

• Microprocessor and digital electronics lab experiments

What's in the Box

• 1 × DAC0808 8-bit DAC IC

Tip: The DAC0808 output (pin 4) is a current, so connect it to the inverting input of an op-amp with a feedback resistor to get a voltage. A1 is the most significant bit, the reverse of the usual D0–D7 naming, and the compensation capacitor from pin 16 to VEE shown in the datasheet should not be left out.
