Tutorial Microcontroller MCS ATMEL ISP

DAC IC is used in applications where a digital to 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.

So to convert the current parameter in to voltage parameter we will use op-amp circuit as shown in circuit diagram. And the analog output from DAC is a current quantity and this needed to be converted in to voltage parameter for vac in application easily. Pin configuration DAC is a sixteen pin device and description for each pin is given below.

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. The output analog voltage from op-amp is in linear relation with input digital value and hence DAC conversion with DAC is achieved. 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.

TL — Programmable Reference Dwc. Submitted by admin on 27 October So this device is mainly used for reference and beginner applications and nothing more.

The power supply currents of the DAC are independent of bit codes, and exhibits essentially constant device characteristics over the entire supply voltage range.

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.

Similarly you can also use other application circuits for DAC given in the datasheet. 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 vac DAC with higher resolution, speed and efficiency. The device takes in parallel 8 bit data from a microcontroller or microprocessor and converts that data in to analog signal at the output.
