Bipolar ADC Offset Error
While in bipolar mode, the ADC’s ideal midscale transi-
tion occurs at AGND -0.5 LSB. Bipolar offset error is the
measured deviation from this ideal value.
ADC Gain Error
Gain error is defined as the amount of deviation
between the ideal transfer function and the measured
transfer function, with the offset error removed and with
a full-scale analog input voltage applied to the ADC,
resulting in all ones at DOUT.
DAC Offset Error
DAC offset error is determined by loading a code of
all zeros into the DAC and measuring the analog
output voltage.
DAC Gain Error
DAC gain error is defined as the amount of deviation
between the ideal transfer function and the measured
transfer function, with the offset error removed, when
loading a code of all ones into the DAC.
Aperture Jitter
Aperture jitter (tAJ) is the sample-to-sample variation in
the time between the samples.
Aperture Delay
Aperture delay (tAD) is the time between the rising
edge of the sampling clock and the instant when an
actual sample is taken.
Signal-to-Noise Ratio
For a waveform perfectly reconstructed from digital sam-
ples, signal-to-noise ratio (SNR) is the ratio of full-scale
analog input (RMS value) to the RMS quantization error
(residual error). The ideal, theoretical minimum analog-
to-digital noise is caused by quantization error only and
results directly from the ADC’s resolution (N bits):
SNR = (6.02 x N + 1.76)dB
In reality, there are other noise sources besides quanti-
zation 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. RMS noise
includes all spectral components to the Nyquist
frequency excluding the fundamental, the first five
harmonics, and the DC offset.
