TERMINOLOGY
Offset Error
Offset error is a measure of the difference between the actual
voltage and the ideal voltage at midscale or at zero current
expressed in mV or % FSR.
Gain Error
Gain error is the difference between full-scale error and zero-
scale error. It is expressed in % FSR.
where:
Full-Scale Error is the difference between the actual voltage and
the ideal voltage at full scale.
Zero-Scale Error is the difference between the actual voltage and
the ideal voltage at zero scale.
Linearity Error
Linearity error, or relative accuracy, is a measure of the
maximum deviation from a straight line passing through the
endpoints of the full-scale range. It is measured after adjusting
for gain error and offset error and is expressed in % FSR.
Differential Nonlinearity (DNL)
Differential nonlinearity is the difference between the measured
change and the ideal 1 LSB change between any two adjacent
codes. A specified differential nonlinearity of ±1 LSB maximum
ensures monotonicity.
Common-Mode (CM) Error
Common-mode (CM) error is the error at the output of the
amplifier due to the common-mode input voltage. It is
expressed in % of FSVR/V.
Leakage Current
Leakage current is the current measured at an output pin when
that function is off or high impedance.
Gain Error = Full-Scale Error − Zero-Scale Error

Pin Capacitance
Pin capacitance is the capacitance measured at a pin when that
function is off or high impedance.
Slew Rate
The slew rate is the rate of change of the output voltage
expressed in V/μs.
Output Voltage Settling Time
Output voltage settling time is the amount of time it takes for
the output of a DAC to settle to a specified level for a full-scale
input change.
Digital-to-Analog Glitch Energy
Digital-to-analog glitch energy is the amount of energy that is
injected into the analog output at the major code transition. It
is specified as the area of the glitch in nV-sec. It is measured by
toggling the DAC register data between 0x7FFF and 0x8000.
Digital Crosstalk
Digital crosstalk is defined as the glitch impulse transferred to
the output of one converter due to a change in the DAC register
code of another converter. It is specified in nV-sec.
AC Crosstalk
AC crosstalk is defined as the glitch impulse transferred to the
output of one PMU due to a change in any of the DAC registers
in the package.
ACPSRR
ACPSRR is a measure of the ability of the device to avoid
coupling noise and spurious signals that appear on the supply
voltage pin to the output of the switch. The dc voltage on the
device is modulated by a sine wave of 0.2 V p-p. The ratio of the
amplitude of the signal on the output to the amplitude of the
modulation is the ACPSRR.
