*Stresses above those listed under “Absolute Maximum Ratings” may cause
permanent damage to the device. T his is a stress rating only and functional
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.
CAUTIO N
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. T herefore, proper ESD
precautions are recommended to avoid performance degradation or loss of functionality.
WARNING!
ESD SENSITIVE DEVICE
with all 1s in the DAC after offset error has been adjusted out
and is expressed in LSBs. Gain Error is adjustable to zero with
an external potentiometer.
TERMINO LO GY
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 VREF range.
FEED TH RO UGH ERRO R: Error caused by capacitive cou-
pling from VREF to output with all switches OFF.
RESO LUTIO N: Value of the LSB. For example, a unipolar con-
verter with n bits has a resolution of (2–n) (VREF). A bipolar con-
verter of n bits has a resolution of [2–(n–1)] [VREF]. Resolution in no
way implies linearity.
O UTP UT CAP ACITANCE: Capacity from OUT 1 and
OUT 2 terminals to ground.
O UTP UT LEAKAGE CURRENT: Current which appears
on OUT 1 terminal with all digital inputs LOW or on OUT 2
terminal when all inputs are HIGH. T his is an error current
which contributes an offset voltage at the amplifier output.
GAIN ERRO R: Gain Error is a measure of the output error be-
tween an ideal DAC and the actual device output. It is measured
