CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection.
Although the AD7226 features proprietary ESD protection circuitry, permanent damage may
occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD
precautions are recommended to avoid performance degradation or loss of functionality.
TERMINOLOGY
TOTAL UNADJUSTED ERROR
This is a comprehensive specification which includes full-scale
error, relative accuracy and zero code error. Maximum output
voltage is V
256. The LSB size will vary over the V
code error will, relative to the LSB size, increase as V
creases. Accordingly, the total unadjusted error, which includes
the zero code error, will also vary in terms of LSB’s over the
V
fixed reference voltage of +10 V.
RELATIVE ACCURACY
Relative Accuracy or endpoint nonlinearity, is a measure of the
maximum deviation from a straight line passing through the
endpoints of the DAC transfer function. It is measured after al-
lowing for zero and full-scale error and is normally expressed in
LSB’s 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 max over
the operating temperature range ensures monotonicity.
DIGITAL CROSSTALK
The glitch impulse transferred to the output of one converter
due to a change in the digital input code to another of the con-
verters. It is specified in nV secs and is measured at V
FULL SCALE ERROR
Full-Scale Error is defined as:
Outputs may be shorted to AGND provided that the power dissipation of the

operation of the device at these or any other conditions above those indicated in
the operational sections of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability.
