TERMINOLOGY
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
adjusting for zero and full scale and is normally expressed 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 max over
the operating temperature range ensures monotonicity.
Gain Error
Gain error or full-scale error is a measure of the output error
between an ideal DAC and the actual device output. For the
Temperature Ranges are J, K, L Versions: –40 C to +85 C
Specifications applies to both DACs in AD7528.
Guaranteed by design but not production tested.
Logic inputs are MOS Gates. Typical input current (+25 C) is less than 1 nA.
These characteristics are for design guidance only and are not subject to test.
Feedthrough can be further reduced by connecting the metal lid on the ceramic package
(suffix D) to DGND.

Output Capacitance
Capacitance from OUT A or OUT B to AGND.
Digital to Analog Glitch lmpulse
The amount of charge injected from the digital inputs to the
analog output when the inputs change state. This is normally
specified as the area of the glitch in either pA-secs or nV-secs
depending upon whether the glitch is measured as a current or
voltage signal. Glitch impulse is measured with V
V
Propagation Delay
This is a measure of the internal delays of the circuit and is
defined as the time from a digital input change to the analog
output current reaching 90% of its final value.
Channel-to-Channel Isolation
The proportion of input signal from one DAC’s reference input
which appears at the output of the other DAC, expressed as a
ratio in dB.
Digital Crosstalk
The glitch energy transferred to the output of one converter due
to a change in digital input code to the other converter. Speci-
fied in nV secs.
