ECET 340 Week 4 Homework

Author: Minh Reed


Determine the conversion time for an ADC0804 (8-bit), where 66 clocks per bit are required, if its clock frequency is 50 kHz.
If an 8-bit SAR has Vref = 10 V, what is the binary value for an input voltage of 7.28 V?
What is the percent error for the binary answer found in Problem #2?
Given an 24 MHz bus speed. Write down the line(s) of instruction which set the ATD1 unit for 2MHz conversion frequency, 10-bit resolution and 8 A-to-D clocks per sample time.
What are the values in each of the 16-bits of this register after conversion is complete? Assume the result is unsigned. Show work!
Assume that a position-sensitive potentiometer can measure up to 25 cm over a voltage range of 0 to 5 V. If an 8-bit ADC outputs a value of 0111 1010, what is the distance measured?
