TERMINOLOGY
DYNAMIC RANGE
Dynamic range is the ratio of the rms value of the full scale to
the total rms noise measured with the inputs shorted together
in the bandwidth from 3 Hz to the Nyquist frequency FO/2. The
value for dynamic range is expressed in decibels.
SIGNAL-TO-NOISE RATIO (SNR)
SNR is the ratio of the rms value of the full-scale signal to the
total rms noise in the bandwidth from 3 Hz to the Nyquist fre-
quency FO/2. The value for SNR is expressed in decibels.
TOTAL HARMONIC DISTORTION (THD)
THD is the ratio of the rms sum of all the harmonic components
up to Nyquist frequency FO/2 to the rms value of a full-scale
input signal. The value for THD is expressed in decibels.
INTERMODULATION DISTORTION (IMD)
IMD is the ratio of the rms sum of two sine wave signals of
30 Hz and 50 Hz which are each 6 dB down from full scale to
the rms sum of all intermodulation components within the
bandwidth from 1 Hz to the Nyquist frequency FO/2. The value
for IMD is expressed in decibels.
OFFSET
The offset is the difference between the ideal midscale input volt-
age (0 V) and the actual voltage producing the midscale output
code (code 000000H) at the output of the AD1556. The offset
specification is referred to the output. This offset is intentionally
set at a nominal value of –60 mV (see Sigma-Delta Modulator
section). The value for offset is expressed in mV.
OFFSET ERROR DRIFT
The change of the offset over temperature. It is expressed in mV.
GAIN ERROR
The gain error is the ratio of the difference between the actual
gain and the ideal gain to the ideal gain. The actual gain is the
ratio of the output difference obtained with a full-scale analog
input (
±2.25 V) to the full-scale span (4.5 V) after correction of
the effects of the external components. It is expressed in %.
GAIN ERROR STABILITY OVER TEMPERATURE
The change of the gain error over temperature. It is expressed
in %.
