TERMINOLOGY
Relative Accuracy
Relative accuracy or endpoint linearity is a measure of the
maximum deviation from a straight line passing through
the endpoints of the DAC transfer function. It is
measured after adjusting for zero-scale error and full-scale
error and is expressed in Least Significant Bits.
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
1 LSB maximum ensures monotonicity.
Zero-Scale Error
Zero-scale error is the error in the DAC output voltage
when all 0s are loaded into the DAC register.
Ideally, with all 0s loaded to the DAC and m = all 1s, c =
2
n-1
:
VOUT
(Zero-Scale)
= 0V
Zero-scale error is a measure of the difference between
VOUT (actual) and VOUT (ideal) expressed in mV. It is
mainly due to offsets in the output amplifier.
Offset-Error
Offset error is a measure of the difference between VOUT
(actual) and VOUT (ideal) expressed in mV in the linear
region of the transfer function. Offset error is measured on
the AD5380-5 with Code 32 loaded into the DAC register
and with code 64 on the AD5380-3.
Gain Error
Gain Error is specified in the linear region of the ouput
range between Vout =10mV and Vout =AVdd-50mV. It is
the deviation in slope of the DAC transfer characteristic
from ideal and is expressed in % FSR with the DAC
output unloaded.
DC Crosstalk
This is the DC change in the output level of one DAC at
midscale in response to a fullscale code (all 0’s to all 1’s
and vice versa) and output change of all other DACs. It is
expressed in lsbs.
DC Output Impedance
This is the effective output source resistance. It is
dominated by package lead resistance.
Output Voltage Settling Time
This is the amount of time it takes for the output of a
DAC to settle to a specified level for a 1/4 to 3/4 full-scale
input change and measured from
BUSY
rising edge.
Digital-to-Analog Glitch Energy
This is the amount of energy injected into the analog
output at the major code transition. It is specified as the
area of the glitch in nV-s. It is measured by toggling the
DAC register data between 1FFF Hex and 2000Hex.
DAC-to-DAC Crosstalk
DAC-to-DAC crosstalk is defined as the glitch impulse
that appears at the output of one DAC output due to both
the digital change and subsequent analog O/P change at
another DAC. The victim channel is loaded with mid-
scale and DAC-to-DAC crosstalk is specified in nV-s.
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 V
OUT
pins. It can also be coupled along the
supply and ground lines. This noise is digital feedthrough.
Output Noise Spectral Density
This is a measure of internally generated random noise.
Random noise is characterized as a spectral density (voltage
per root Hertz). It is measured by loading all DACs to
midscale and measuring noise at the output. It is
measured in nV/(
Hz
)
1/2
in a 1 Hz bandwidth at 10KHz.
