TERMINOLOGY
Offset Error
Offset error is a measure of the difference between actual and
ideal voltage expressed in mV.
Gain Error Gain error is the difference between full-scale error
and zero-scale error. It is expressed in %.
Linearity Error
Relative accuracy, or endpoint linearity, 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 offset error and gain error and is expressed in % FSR.
CM Error
Common Mode Error is the error at the output of the amplifier
due to the common mode input voltage. It is expressed in % of
FSR/V.
Clamp Accuracy
Clamp accuracy is a measure of where the clamps begin to
function fully and limit the clamped voltage or current.
Leakage Current
Current measured at an output pin, when that function is off or
high impedance.
Pin Capacitance
Capacitance measured at a pin when that function is off or high
impedance.
Slew Rate
The rate of change of output voltage, expressed in V/μs.
Gain Error = Full-Scale Error − Zero-Scale Error

DAC SPECIFIC TERMS
Differential Nonlinearity
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 ±1LSB maximum
ensures monotonicity.
Output Voltage Settling Time
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
The amount of energy injected into the analog output at the
major code transition. The area of the glitch in is specified in
nV-s. It is measured by toggling the DAC register data between
0x1FFF and 0x2000.
Digital Crosstalk
The glitch impulse transferred to the output of one converter
due to a change in the DAC register code of another converter
is defined as the digital crosstalk and is specified in nV-s.
Digital Feedthrough
When the device is not selected, high frequency logic activity
on the device’s digital inputs can be capacitively coupled both
across and through the device to show up as noise on the
VOUT pins. It can also be coupled along the supply and
ground lines. This noise is digital feedthrough.
