TERMINOLOGY
Integral Nonlinearity
Integral nonlinearity
is the maximum deviation of the actual,
adjusted DAC output from the ideal analog output (a straight
line drawn from 0 to FS 1 LSB) for any bit combination. This
is also referred to as relative accuracy.
Differential Nonlinearity
Differential nonlinearity is the measure of the change in the
analog output, normalized to full scale, associated with a 1 LSB
change in the digital input code. Monotonic behavior requires
that the differential linearity error be greater than or equal to
1 LSB over the temperature range of interest.
Monotonicity
A DAC is monotonic if the output either increases or remains
constant for increasing digital inputs with the result that the
output is always a single-valued function of the input.
Gain Error
Gain error is a measure of the output error between an ideal
DAC and the actual device output with all 1s loaded after offset
error has been adjusted out.
Offset Error
Offset error is a combination of the offset errors of the voltage-
mode DAC and the output amplifier and is measured with all 0s
loaded in the DAC.
Bipolar Zero Error
When the AD660 is connected for bipolar output and 10…000
is loaded in the DAC, the deviation of the analog output from
the ideal midscale value of 0 V is called the bipolar zero error.
Drift
Drift is the change in a parameter (such as gain, offset, and bipolar
zero) over a specified temperature range. The drift temperature
coefficient, specified in ppm/°C, is calculated by measuring the
parameter at TMIN, 25°C, and TMAX, and dividing the change in
the parameter by the corresponding temperature change.
Total Harmonic Distortion + Noise
Total harmonic distortion + noise (THD + N) is defined as the
ratio of the square root of the sum of the squares of the values of
the harmonics and noise to the value of the fundamental input
frequency. It is usually expressed in percent (%).
THD + N is a measure of the magnitude and distribution of
linearity error, differential linearity error, quantization error,
and noise. The distribution of these errors may be different,
depending upon the amplitude of the output signal. Therefore,
to be the most useful, THD + N should be specified for both
large and small signal amplitudes.
Signal-To-Noise Ratio
The signal-to-noise ratio is the ratio of the amplitude of the output
when a full-scale signal is present to the output with no signal
present. The signal-to-noise ratio is measured in decibels (dB).
Digital-To-Analog Glitch Impulse
Digital-to-analog glitch impulse is the amount of charge
injected from the digital inputs to the analog output when the
inputs change state. This is measured at half scale when the DAC
switches around the MSB and as many as possible switches
change state, that is, from 011…111 to 100…000.
Digital Feedthrough
When the DAC is not selected (that is, CS is held high), high
frequency logic activity on the digital inputs is capacitively
coupled through the device to show up as noise on the VOUT pin.
This noise is digital feedthrough.
