Note 1:
100% production tested at T
A
= +25°C and T
A
= +85°C. Guaranteed by design to T
A
= -40°C.
Note 2:
The DNL and INL are measured with the device configured as a voltage-divider with H = V
DD
and L = V
SS
. The wiper termi-
nal (W) is unloaded and measured with a high-input-impedance voltmeter.
Note 3:
The DNL_R and INL_R are measured with D.N.C. unconnected and L = V
SS
= 0. For V
DD
= 5V, the wiper terminal is driven
with a source current of I
W
= 80μA for the 50k
device and 400μA for the 10k
device. For V
DD
= 3V, the wiper terminal is
driven with a source current of 40μA for the 50k
device and 200μA for the 10k
device.
Note 4:
The wiper resistance is measured using the source currents given in Note 3.
Note 5:
The device draws higher supply current when the digital inputs are driven with voltages between (V
DD
- 0.5V) and (GND +
0.5V). See Supply Current vs. Digital Input Voltage in the
Typical Operating Characteristics
.
Note 6:
Wiper settling test condition uses the voltage-divider configuration with a 10pF load on W. Transition code from 00000 00000
to 01111 01111 and measure the time from
CS
going high to the wiper voltage settling to within 0.5% of its final value.
