Given Iref = 2 mA for a DAC1408 IC, find Iout for the input 1110 1110 3. Find the number of discrete voltages output by a 12-bit DAC. Show work. 4. Use the internet to locate the data sheet for an MC1408 DAC. From it find, for the MC1408-7 version, the following: a. The settling time b. Accuracy at full scale output current (1.99 mA), 25ºC c. Output current range when -7V <vee="">< -15v="" is="" used.=""> 5. Assume that an MC1408 DAC is attached to Port T of an HC12 Microprocessor as shown below. Verify that the program below outputs 8 different values to the DAC and determine the output voltage (Vout) after each output .
