DEFINITIONS OF SPECIFICATIONS
Analog Bandwidth
The analog input frequency at which the spectral power of the
fundamental frequency (as determined by FFT analysis) is re-
duced by 3 dB.
Aperture Delay
The delay between the rising edge of the ENCODE command
and the instant at which the analog input is sampled.
Aperture Uncertainty (Jitter)
The sample-to-sample variation in aperture delay.
Differential Gain
The percentage of amplitude change of a small high frequency
sine wave (3.58 MHz) superimposed on a low frequency signal
(15.734 kHz).
Differential Nonlinearity
The deviation of any code from an ideal 1 LSB step.
Differential Phase
The phase change of a small high frequency sine wave (3.58 MHz)
superimposed on a low frequency signal (15.734 kHz).
Harmonic Distortion
The rms value of the fundamental divided by the rms value of
the harmonic.
Integral Nonlinearity
The deviation of the transfer function from a reference line mea-
sured in fractions of 1 LSB using a “best straight line” deter-
mined by a least square curve fit.
Minimum Conversion Rate
The encode rate at which the SNR of the lowest analog signal
frequency tested drops by no more than 3 dB below the guaran-
teed limit.
Maximum Conversion Rate
The encode rate at which parametric testing is performed.
Output Propagation Delay
The delay between the 50% point of the falling edge of the
ENCODE command and the 1 V/4 V points of output data.
Overvoltage Recovery Time
The amount of time required for the converter to recover to
10-bit accuracy after an analog input signal 150% of full scale is
reduced to the full-scale range of the converter.
Power Supply Rejection Ratio (PSRR)
The ratio of a change in input offset voltage to a change in
power supply voltage.
Signal-to-Noise Ratio (SNR)
The ratio of the rms signal amplitude to the rms value of
“noise,” which is defined as the sum of all other spectral com-
ponents, including harmonics but excluding dc, with an analog
input signal 1 dB below full scale.
Signal-to-Noise Ratio (Without Harmonics)
The ratio of the rms signal amplitude to the rms value of
“noise,” which is defined as the sum of all other spectral com-
ponents, excluding the first eight harmonics and dc, with an
analog input signal 1 dB below full scale.
Transient Response
The time required for the converter to achieve 10-bit accuracy
when a step function is applied to the analog input.
Two-Tone Intermodulation Distortion (IMD) Rejection
The ratio of the power of either of two input signals to the
power of the strongest third-order IMD signal.
