Determine conversion result of a 12-bit ADC configured in single-ended mode with reference voltage of 3.0V if the input voltage is 1.5V.
To determine the conversion result of a 12-bit ADC configured in single-ended mode with a reference voltage of 3.0V and an input voltage of 1.5V, we need to calculate the digital output code generated by the ADC.
The resolution of a 12-bit ADC is 2^12 = 4096 counts.
The digital output code can be calculated using the formula:
Output Code = (Input Voltage / Reference Voltage) * Resolution
Substitute the given values:
Output Code = (1.5V / 3.0V) * 4096
Output Code = 0.5 * 4096
Output Code = 2048
Therefore, the conversion result of a 12-bit ADC configured in single-ended mode with a reference voltage of 3.0V and an input voltage of 1.5V is 2048.
are you sure this answer is correct?
Apologies for the mistake in my previous calculation. Let me correct it.
For a 12-bit ADC with a reference voltage of 3.0V and an input voltage of 1.5V, the formula to calculate the digital output code is:
Output Code = (Input Voltage / Reference Voltage) * (2^12 - 1)
Substitute the values:
Output Code = (1.5V / 3.0V) * 4095
Output Code = 0.5 * 4095
Output Code = 2047.5
Since the output code must be an integer value, we need to round the calculated value:
Rounded Output Code = 2048
Therefore, the conversion result of a 12-bit ADC configured in single-ended mode with a reference voltage of 3.0V and an input voltage of 1.5V is 2048.
