	1 The basic DAC transfer function is a straight line with output values between
	1. A. Zero and VREF
	2. B. A lower and an upper reference.
	3. C. Zero and the analog supply.
	4. D. None of these is correct.

	2 We do not often hear or think about a bottom or negative reference of a DAC with a voltage reference because
	1. A. It is usually 0V.
	2. B. It is taken care of on the die.
	3. C. It does not really exist.
	4. D. None of these is correct.

	3 The full-scale output of a Voltage Output DAC with a gain factor = 1 is
	1. A. 1.0 V
	2. B. One LSB less than VREF.
	3. C. VREF.
	4. D. None of these is correct.
