What is DAC0808?
The DAC0808 is an 8-bit monolithic digital-to-analog con- verter (DAC) featuring a full scale output current settling time. of 150 ns while dissipating only 33 mW with ±5V supplies. No reference current (IREF) trimming is required for most. applications since the full scale output current is typically ±1.
What is the output of DAC0808?
Explanation: The output of a DAC0808 is in the form of a current.
What is size of DAC0808 IC?
The DAC0808 is an 8-bit monolithic digital-to-analog converter (DAC) featuring a full scale output current settling time of 150 ns while dissipating only 33 mW with ±5V supplies.
What is the max ref current of DAC0808?
Typically, the DAC0808 is monotonic for all values of reference current above 0.5 mA. The recommended range for operation with a DC reference current is 0.5 to 4 mA.

How the output current of DAC0808 is converted in voltage?
It takes parallel input in the form of 8-bits. The DAC0808 chip converts this digital input into a current ( ). We convert this current into an analog voltage by connecting a resistor at the output. We can apply 8-bit digital input to DAC0808 digital inputs pins through any microcontroller like 8051 or PIC etc.
Why Open is used at the output of DAC0808?
So to convert the current parameter into voltage parameter, we will use an op-amp circuit as shown in the circuit diagram. This op-amp circuit is called current-to-voltage converter. The output analog voltage from op-amp is in linear relation with input digital value and hence DAC conversion with DAC0808 is achieved.
How many data pins are available for digital data in DAC0808?
As you can depict from DAC0808 pinout diagram that it consists of 16 pins. Eight pins are digital input pins and IOUT is an analog output pin along with Vref+ and Vref- used to set a reference point for analog output.
Why op amp is used at the output of DAC0808?
What is a dac0808 IC used for?
DAC0808 is a D/A converter IC and is used for converting 8 bit digital data input to analog signal output. It is a monolithic IC featuring a full scale output current settling time of 150 ns while dissipating only 33 mW with ±5V supplies.
