TERMINOLOGY
RELATIVE ACCURACY (LINEARITY)
Relative accuracy, or endpoint linearity, is a measure of the
maximum deviation of the DAC transfer function from a straight
line passing through the endpoints of the transfer function. It is
measured after allowing for zero and full-scale errors and is ex-
pressed in LSBs or as a percentage of full-scale reading.
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 or less
over the operating temperature range ensures monotonicity.
BIPOLAR ZERO ERROR
Bipolar zero error is the voltage measured at V
DAC is loaded with all 0s. It is due to a combination of offset
errors in the DAC, amplifier and mismatch between the internal
gain resistors around the amplifier.

FULL-SCALE ERROR
Full-scale error is a measure of the output error when the am-
plifier output is at full scale (full scale is either positive or nega-
tive full scale).
DIGITAL-TO-ANALOG GLITCH IMPULSE
This is the voltage spike that appears at the output of the DAC
when the digital code in the DAC latch changes before the out-
put settles to its final value. The energy in the glitch is specified
in nV secs, and is measured for an all codes change (0000 0000
0000 to 1111 1111 1111).
DIGITAL FEEDTHROUGH
This is a measure of the voltage spike that appears on V
result of feedthrough from the digital inputs on the AD7233. It
is measured with LDAC held high.

Stresses above those listed under Absolute Maximum Ratings may cause perma-
nent damage to the device. This is a stress rating only; functional operation of the
device at these or any other conditions above those listed in the operational sections
of this specification is not implied. Exposure to absolute maximum rating condi-
tions for extended periods may affect device reliability.
The output may be shorted to voltages in this range provided the power dissipation
of the package is not exceeded. Short circuit current is typically 80 mA.
