distortion includes all spectral components to the
Nyquist frequency excluding the fundamental and the
DC offset.
Effective Number of Bits (ENOB)
ENOB indicates the global accuracy of an ADC at a
specific input frequency and sampling rate. An ideal
ADC’s error consists of quantization noise only. ENOB
is calculated from a curve fit referenced to the theoreti-
cal full-scale range.
Total Harmonic Distortion (THD)
THD is the ratio of the RMS sum of the first 15 harmon-
ics of the input signal to the fundamental itself. This is
expressed as:
where V1 is the fundamental amplitude, and V
2
through
V
16
are the amplitudes of the 2nd- through 16th-order
harmonics (HD2 through HD16).
Spurious-Free Dynamic Range (SFDR)
SFDR is the ratio expressed in decibels of the RMS
amplitude of the fundamental (maximum signal compo-
nent) to the RMS value of the next largest spurious
component, excluding DC offset.
Third-Order Intermodulation (IM3)
IM3 is the total power of the third-order intermodulation
product to the Nyquist frequency relative to the total
input power of the two input tones, f
IN
1 and f
IN
2. The
individual input tone levels are at -7dBFS. The third-order
intermodulation products are located at 2 x f

Full-Power Bandwidth
A large -1dBFS analog input signal is applied to an
ADC and the input frequency is swept up to the point
where the amplitude of the digitized conversion result
has decreased by -3dB. This point is defined as full-
power input bandwidth frequency.
