DAC0830 DATASHEET PDF

Bipolar Output Voltage with a Fixed Reference. The addition of a second op amp to the previous circuitry can be used to generate a bipolar output voltage from. This, in effect, gives sign significance to the MSB of the digital input word and allows. The polarity of the reference can also be reversed to realize. Figure

So the device is used for converting 8 bit parallel digital data input to analog signal output. The chip is designed with CMOS technology to achieve low power consumption and low output leakage current errors. The design also includes special circuitry that provides TTL logic input voltage level compatibility. Double buffering of the device allows outputting a voltage corresponding to one digital word while holding the next digital word.

This also permits the simultaneous updating of any number of DACs. DAC also designed with silicon-chromium R-2R resistor ladder network which divides the reference current and provides the circuit with excellent temperature tracking characteristics 0. DAC IC basically used in applications where an 8 bit digital data needed to be converted to analog value.

The device is specifically designed for it to be interfaced directly with the , , , Z80, and other popular microprocessors. The device is available in the market for low cost and can be easily worked with. All these control pins need to be setup appropriately as mentioned above for successful DAC conversion of the device. Now for understanding the working let us consider the example application circuit given in the datasheet. We can use the circuit to develop applications without worry as the circuit is tested working.

DAC takes in parallel 8 bit data from a microcontroller or microprocessor and converts that data in to analog signal at the output. This analog signal is the current quantity that is directly proportional to the input digital value and this current parameter needed to be converted in to voltage parameter for further use. 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 analog voltage output from the op-amp circuit is in direct relation with inputted digital value and hence DAC conversion with DAC is achieved. Subscribe to stay updated with industry's latest Electronics components and news.
