Resistor position nonlinearity error R-INL is the deviation from an ideal value measured between the maximum resistance and the minimum resistance wiper posi-
tions. R-DNL measures the relative step change from ideal between successive tap positions. Parts are guaranteed monotonic. See Figure 27. T est Circuit.

INL and DNL are measured at V
with the RDAC configured as a potentiometer divider similar to a voltage output D/A converter. V

DD
and V
B
= 0 V. DNL
specification limits of

Bandwidth, noise and settling time are dependent on the terminal resistance value chosen. T he lowest R value results in the fastest settling time and highest band-
width. T he highest R value results in the minimum overall power consumption.

All dynamic characteristics use V
= +15 V and V
= –15 V.

See timing diagram for location of measured values. All input control voltages are specified with t
R
= t
F
= 1 ns (10% to 90% of V
DD
) and timed from a voltage level
of 1.6 V. Switching characteristics are measured using both V
= +5 V or +15 V.

WARNING!
ESD SENSITIVE DEVICE
C AUT ION
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 AD7376 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.
