TERMINOLOGY
RELATIVE ACCURACY: A measure of the deviation from a
straight line through the end points of the DAC transfer function.
Normally expressed as a percentage of full scale range. For the
AD7524 DAC, this holds true over the entire V
RESOLUTION: Value of the LSB. For example, a unipolar con-
verter with n bits has a resolution of (2
verter of n bits has a resolution of [2
way implies linearity.
GAIN ERROR: Gain Error is a measure of the output error be-
tween an ideal DAC and the actual device output. It is measured

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 AD7524 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.

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.

OUTPUT LEAKAGE CURRENT: Current which appears
on OUT1 terminal with all digital inputs LOW or on OUT2
terminal when all inputs are HIGH. This is an error current
which contributes an offset voltage at the amplifier output.
