Gain Error
The gain error is the difference between the ideal and
actual value of the analog input difference between the
first and last transitions of the ADC output. The first
transition is from digital code 0 to code 1, and the last
from code (2N-2) to code (2N-1), where N = number of
ADC bits for straight binary output code. For the
MAX1153/MAX1154, the ideal difference in the input
voltage between code transitions 0 to 1 and code tran-
sitions 1022 to 1023 is 1022 x LSB. For the MAX1153,
this is 2.5V - 2 x LSB = 2.495117, and for the MAX1154,
this is 4.096V - 2 x LSB = 4.088. Gain error is a DC
specification, usually normalized to the FS ideal analog
value and given in percent of FSR or ppm.
Signal-to-Noise Ratio
For a waveform perfectly reconstructed from digital
samples, signal-to-noise ratio (SNR) is the ratio of the
full-scale analog input (RMS value) to the RMS quantiza-
tion error (residual error). The ideal theoretical minimum
analog-to-digital noise is caused by quantization error
only, results directly from the ADC’s resolution (N bits),
and can be calculated with the following equation:
SNR = (6.02 x N + 1.76)dB
There are other noise sources besides quantization
noise, including thermal noise, reference noise, clock
jitter, etc. Therefore, SNR is calculated by taking the
ratio of the RMS signal to the RMS noise, which
includes all spectral components minus the fundamen-
tal, the first five harmonics, and the DC offset.
Signal-to-Noise Plus Distortion
Signal-to-noise plus distortion (SINAD) is the ratio of the
fundamental input frequency’s RMS amplitude to the
RMS equivalent of all other ADC output signals:
SINAD (dB) = 20 x log (SignalRMS / NoiseRMS)
There are other noise sources besides quantization
noise, including thermal noise, reference noise, clock
jitter, etc. Therefore, SINAD is calculated by taking the
ratio of the full-scale signal to the RMS noise, which
includes all spectral components minus the fundamen-
tal and the first five harmonics.
Total Harmonic Distortion (THD)
Total harmonic distortion (THD) is the ratio of the RMS
sum of the first five harmonics of the input signal to the
fundamental itself. This is expressed as:
where V1 is the fundamental RMS value, and V2
through V5 are the RMS values of the 2nd- through 5th-
order harmonics, respectively.
Power-Supply Rejection
Power-supply rejection is the ratio between the change
in the ADC full-scale output to the change in power-
supply voltage when the power-supply voltage is varied
from its nominal value. It is specified in V/V or V/V.
