Intersil products are manufactured, assembled and tested utilizing ISO9001 quality systems as noted

in the quality certifications found at www.intersil.com/en/support/qualandreliability.html

Intersil products are sold by description only. Intersil may modify the circuit design and/or specifications of products at any time without notice, provided that such

modification does not, in Intersil's sole judgment, affect the form, fit or function of the product. Accordingly, the reader is cautioned to verify that datasheets are

current before placing orders. Information furnished by Intersil is believed to be accurate and reliable. However, no responsibility is assumed by Intersil or its

subsidiaries for its use; nor for any infringements of patents or other rights of third parties which may result from its use. No license is granted by implication or

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

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.
