Linear-Taper Digital Potentiometers

_______________________________________________________________________________________
Note 1: All devices are production tested at TA = +85°C and are guaranteed by design and characterization for -40°C < TA < +85°C.
Note 2: DNL and INL are measured with the potentiometer configured as a voltage-divider with H_ = VDD and L_ = 0. The wiper terminal
is unloaded and measured with an ideal voltmeter.
Note 3: DNL and INL are measured with the potentiometer configured as a variable resistor. H_ is unconnected and L_ = 0. For VDD =
+5V, the wiper terminal is driven with a source current of 400A for the 10k
configuration, 80A for the 50k configuration,
and 40A for the 100k
configuration. For VDD = +3V, the wiper terminal is driven with a source current of 200A for the 10k
configuration, 40A for the 50k
configuration, and 20A for the 100k configuration.
Note 4: The wiper resistance is the worst value measured by injecting the currents given in Note 3 into W_ with L_ = GND. RW =
(VW - VH) / IW.
Note 5: The device draws higher supply current when the digital inputs are driven with voltages between (VDD - 0.5V) and (GND +
0.5V). See Supply Current vs. Digital Input Voltage in the
Typical Operating Characteristics section.
Note 6: Wiper at midscale with a 10pF load.
Note 7: Wiper-settling time is the worst-case 0-to-50% rise time, measured between tap 0 and tap 127. H_ = VDD, L_ = GND, and
the wiper terminal is unloaded and measured with a 10pF oscilloscope probe (see Tap-to-Tap Switching Transient in the
Typical Operating Characteristics section).
Note 8: Digital timing is guaranteed by design and characterization, and is not production tested.
DC ELECTRICAL CHARACTERISTICS (continued)
(VDD = +2.7V to +5.25V, VH = VDD, VL = GND, TA = -40
°C to +85°C, unless otherwise noted. Typical values are at VDD = +5.0V,
TA = +25
°C, unless otherwise noted.) (Note 1)
