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 for the voltage-divider with H_ = V
DD
and L_ = V
SS
. The wiper terminal (W_) is unloaded
and measured with a high-input-impedance voltmeter.
Note 3:
The DNL and INL are measured with L_ = V
SS
= 0. For V
DD
= 5V, the wiper terminal is driven with a current source of I
W
=
80μA for the 50k
device and I
W
= 400μA for the 10k
device. For V
DD
= 3V, the wiper terminal is driven with a current
source of I
W
= 40μA for the 50k
device and I
W
= 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 the Supply Current vs. Digital Input Voltage graph in the
Typical Operating Characteristics
.
Note 6:
Wiper settling test condition uses the voltage-divider with a 10pF load on W_. Transition code from 0 to 495 and measure
the time from
CS
going high to the wiper voltage settling to within 0.5% of its final value.
