  • Question 2
    1 / -0

    An n-bit DAC is desired to change in 1 mV increments while using a reference voltage of 5 V. The number of bits ‘n’ required for the DAC is _______.

  • Question 3
    1 / -0

    A 10-bit ADC with a full scale output voltage of 10.24 V is designed to have a ± LSB/2 accuracy. If the ADC is calibrated at 25°C and the operating temperature ranges from 0°C to 50°C. Then the maximum net temperature coefficient of the ADC should not exceed.
