National Semiconductor – datasheet pdf
For working of device DAC we have connected a voltage source of 15V as shown in diagram. The design also includes special circuitry that provides TTL logic input voltage level compatibility.
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. The chip is designed with CMOS technology to achieve low power consumption and low output leakage current errors.
DAC Pinout, Features & Datasheet
Double buffering of the device allows outputting a voltage corresponding to one digital word while holding the next digital word. Now for understanding the working let us consider the example application circuit given in the datasheet. This op-amp circuit is called current-to-voltage converter. DAC also designed with silicon-chromium R-2R resistor ladder network dqc0831 divides the reference current and provides the circuit with excellent temperature tracking characteristics 0.
So to convert the current parameter in to voltage parameter we will use op-amp circuit as shown in circuit diagram. Pin Configuration DAC is a twenty pin device and description for each pin is given below.
DAC IC basically used in applications where an 8 bit digital data needed to be converted to analog value. This analog signal is the current quantity that is directly proportional to the input digital value and this current parameter needed dad0831 be converted in to voltage parameter for further use. TL — Programmable Reference Voltage.
All these control pins need to be setup appropriately as mentioned above for successful DAC conversion of the device. Submitted by admin on 21 November So the device is used for converting 8 bit parallel datwsheet data input to analog signal output.
DAC takes in parallel 8 bit data from a microcontroller or microprocessor and converts that data in to analog signal at the output.
The datasjeet 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. This also permits the simultaneous updating of any number of DACs. We can use the circuit to develop applications without worry as the circuit is tested working.
