DAC0808 DATASHEET PDF

The chip used to be popular a decade ago and its applications used to be many but at present there are many modern IC which can perform DAC with higher resolution, speed and efficiency. So this device is mainly used for reference and beginner applications and nothing more. How to use DAC IC A typical application circuit for DAC is already given in the datasheet and we can use that circuit to develop applications without worry as the circuit is tested working. This is a major drawback which is eliminated in modern DAC to make them work from a single power source. Working The device takes in parallel 8 bit data from a microcontroller or microprocessor and converts that data in to analog signal at the output. And the analog output from DAC is a current quantity and this needed to be converted in to voltage parameter for using in application easily.

The chip used to be popular a decade ago and its applications used to be many but at present there are many modern IC which can perform DAC with higher resolution, speed and efficiency. So this device is mainly used for reference and beginner applications and nothing more. How to use DAC IC A typical application circuit for DAC is already given in the datasheet and we can use that circuit to develop applications without worry as the circuit is tested working.

This is a major drawback which is eliminated in modern DAC to make them work from a single power source. Working The device takes in parallel 8 bit data from a microcontroller or microprocessor and converts that data in to analog signal at the output.

And the analog output from DAC is a current quantity and this needed to be converted in to voltage parameter for using in application easily. So to convert the current parameter in to voltage parameter we will use op-amp circuit as shown in circuit diagram.

This op-amp circuit is called current-to-voltage converter. The output analog voltage from op-amp is in linear relation with input digital value and hence DAC conversion with DAC is achieved. Similarly you can also use other application circuits for DAC given in the datasheet.
