Pin configuration DAC is a sixteen pin device and description for each pin is given below.
This is a major drawback which is eliminated in modern 08808 to make them work from a single power source. So this device is mainly used for reference and beginner applications and nothing more.
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. This op-amp circuit is called current-to-voltage converter.
The chip accuracy of conversion is good and power consumption is also low to make it popular. A typical application circuit for DAC is already given dzc the datasheet and we can use that circuit to develop applications without worry as the circuit is tested working.
The output analog voltage from op-amp is in linear relation with input digital value and hence DAC conversion with DAC is achieved. The chip used dxtasheet 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.
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.
TL — Programmable Reference Voltage. So to convert the current parameter in to voltage parameter we will use op-amp circuit as shown in circuit diagram.
The power supply currents of the DAC are independent of bit codes, and exhibits essentially constant device characteristics over the entire supply voltage range. DAC IC is used in applications where a digital to analog conversion is required.
