DAC Datasheet(PDF) – National Semiconductor (TI)
For working of device DAC we have connected a voltage source of 15V as shown in diagram. Double buffering of the device allows outputting a voltage corresponding to one digital word while holding the next digital word.
Submitted by admin on 21 November The analog voltage output from the op-amp circuit is in direct relation datashwet inputted digital value and hence DAC conversion with DAC is achieved. TL — Programmable Reference Voltage.
This analog signal is dztasheet 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.
The chip is designed with CMOS technology to achieve low power consumption and low output leakage current errors. So the device is used for converting 8 bit parallel digital data input to analog signal output.
The device is specifically designed for it to be interfaced directly with the,Z80, and other popular microprocessors.
So to convert the current parameter in to voltage parameter we will use op-amp circuit as shown in circuit diagram.
The device is available in the market for low datasbeet and can be easily worked with. Pin Configuration DAC is a twenty pin device and description for each pin is given below. This op-amp circuit is called current-to-voltage converter.
DAC IC basically used in applications where an 8 bit digital data needed to be converted to analog value. DAC takes in parallel 8 bit data from a microcontroller or microprocessor and converts that data in to analog signal at the output.
DAC Technical Data
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.
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. This also permits the simultaneous updating of any number of DACs. The design also includes special circuitry that provides TTL logic input voltage level compatibility.
All these control pins need to be setup appropriately as mentioned above for successful DAC conversion of the device.
