*Stresses above those listed under “Absolute Maximum Ratings” may cause
permanent damage to the device. This is a stress rating only, and 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 conditions for extended periods may affect device reliability.
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 AD7111/AD7111A 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
RESOLUTION: Nominal change in attenuation when moving
between two adjacent codes.
MONOTONICITY: The device is monotonic if the analog out-
put decreases (or remains constant) as the digital code increases.
FEEDTHROUGH ERROR: That portion of the input signal
which reaches the output when all digital inputs are high. See
section on Applications.
OUTPUT LEAKAGE CURRENT: Current which appears on
the IOUT terminal with all digital inputs high.
TOTAL HARMONIC DISTORTION: A measure of the
harmonics introduced by the circuit when a pure sinusoid is
applied to the input. It is expressed as the harmonic energy
divided by the fundamental energy at the output.
ACCURACY: The difference (measured in dB) between the
ideal transfer function as listed in Table I and the actual transfer
function as measured with the device.
OUTPUT CAPACITANCE: Capacitance from IOUT to
ground.
DIGITAL-TO-ANALOG GLITCH IMPULSE: 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 VIN = AGND.
PROPAGATION DELAY: This is a measure of the internal
delays of the circuit and is defined as the time from a digital in-
put change to the analog output current reaching 90% of its
final value.
