So this device is mainly used for reference and beginner applications and nothing more.
Pin configuration DAC is a sixteen pin device and description for each pin is given below. So to convert the current parameter in to voltage parameter we will use op-amp circuit as shown in circuit diagram. Submitted by admin on 27 October TL — Programmable Reference Voltage. This sac0808 circuit is called current-to-voltage converter.
National Semiconductor – datasheet pdf
The chip accuracy of conversion is good and power consumption is also low to make it popular. The chip used to be popular a decade ago and its applications dtaasheet to be many but at present there are many modern IC which can perform DAC with higher resolution, speed and efficiency.
This is a major drawback which is eliminated in modern DAC to make them work from a single power source. 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 power supply currents of the DAC are independent of bit codes, and exhibits essentially constant device characteristics over the entire supply voltage range. How to use DAC IC A typical application circuit for DAC is already given in the datasheet and datashert can use that circuit to develop applications without worry as the circuit is tested working.
DAC IC is used in applications where a digital sac0808 analog conversion is required. 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.
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.
Similarly you can also use other application circuits for DAC given in the datasheet. The device takes in parallel 8 bit data from a microcontroller or microprocessor and converts that data in to analog signal at the output. The output analog voltage from datasueet is in linear relation with input digital value and hence DAC conversion with DAC is achieved.
