Detailed explanation-1: -Explanation: Zener is connected between OUT1 and OUT2 pins of AD7523 to save from negative transients. Explanation: An operational amplifier is used as a current-to-voltage converter to convert the current output to output voltage and also provides additional driving capability to the DAC.
Detailed explanation-2: -The resolution of either a digital-to-analog converter (DAC) or an analog-to-digital converter (ADC) is the measure of how finely its output may change between discrete, binary steps. For instance, an 8-bit DAC with an output voltage range of 0 to 10 volts will have a resolution of 39.22 mV.
Detailed explanation-3: -Interfacing DAC0800 with 8086 Ad 7523 8-Bit Multiplying DAC: Intersil‟s AD 7523 is a 16 pin DIP, multiplying digital to analog converter, containing R-2R ladder(R=10K) for digital to analog conversion along with single pole double through NMOS switches to connect the digital inputs to the ladder.
