TASK 2: Design and simulate the circuit to accommodate 8-bit ADC 0804 that utilizes LEDs to indicate its binary output value. Use a reference voltage of 2.5V to 5 VDC. Observe the circuit such that it will continually update its binary output for a changing analog input signal from the sensor. Records all result in Table 1. Simulation Procedure: a) Show the design for circuit development. Refer to the datasheet of National/Fairchild DC0804 in Figure 1 for pin function descriptions (10 marks) b) Simulate for the above circuit designed using software engineering e.g. Multisim or Pspice. Adjust variable resistance until Vin (pin 6) is equal to V. Attached, the simulation files for numbers 3, 8, and 12 in the final report (9 marks) c) Complete the following Table 1 of ADC binary output values for given voltage input values. Verified the simulation results using calculation (39 marks) d) Evaluate in detail for the step of calculation for numbers 3, 8, and 12 only (12 marks) S- 20vec (OR VRES) RD 2 19CLKR WR3 18DEO (LSE) CLK N-4 17081 INTR-5 ADC0804 16182 ()-6 15083 -- 14-084 A GND-8 13 DAS V/249 12086 D GND 10 11087 (MSB) Figure 1 TABLE 1 ADC RESULTS FROM SIMULATION AND CALCULATION Number Binary Output Indicated (X7-XO) Binary Output (Calculated) 1 2 3 un WN 4 5 6 Vin (Pin 6)-(V) 0.000 0.020 0.040 0.080 0.160 0.320 0.640 1.280 2.500 3.750 4.375 4.680 5.000 7 8 9 10 11 12 13 TASK 2: Design and simulate the circuit to accommodate 8-bit ADC 0804 that utilizes LEDs to indicate its binary output value.
