I2E The Intersil Interleave Engine. This highly configurable
circuitry performs estimates of offset, gain, and sample time
skew mismatches between the core converters, and updates
analog adjustments for each to minimize interleave spurs.
Integral Non-Linearity (INL) is the maximum deviation of the
A/D’s transfer function from a best fit line determined by a least
squares curve fit of that transfer function, measured in units of
LSBs.
Least Significant Bit (LSB) is the bit that has the smallest value or
weight in a digital word. Its value in terms of input voltage is
VFS/(2N-1) where N is the resolution in bits.
Missing Codes are output codes that are skipped and will never
appear at the A/D output. These codes cannot be reached with
any input value.
Most Significant Bit (MSB) is the bit that has the largest value or
weight.
Pipeline Delay is the number of clock cycles between the
initiation of a conversion and the appearance at the output pins
of the data.
Power Supply Rejection Ratio (PSRR) is the ratio of the observed
magnitude of a spur in the A/D FFT, caused by an AC signal
superimposed on the power supply voltage.
Signal to Noise-and-Distortion (SINAD) is the ratio of the RMS
signal amplitude to the RMS sum of all other spectral
components below one half the clock frequency, including
harmonics but excluding DC.
Signal-to-Noise Ratio (without Harmonics) is the ratio of the RMS
signal amplitude to the RMS sum of all other spectral
components below one-half the sampling frequency, excluding
harmonics and DC.
SNR and SINAD are either given in units of dB when the power of
the fundamental is used as the reference, or dBFS (dB to full
scale) when the converter’s full-scale input power is used as the
reference.
Spurious-Free-Dynamic Range (SFDR) is the ratio of the RMS
signal amplitude to the RMS value of the largest spurious
spectral component. The largest spurious spectral component
may or may not be a harmonic.
