Digital Potentiometers

Note 1: Linearity is defined in terms of the H_ to L_ code-dependent resistance.
Note 2: The DNL and INL are measured with the potentiometer configured as a voltage divider with H_ = VDD and L_ = GND. The
wiper terminal is unloaded and measured with an ideal voltmeter.
Note 3: The DNL and INL are measured with the potentiometer configured as a variable resistor. For the 3-terminal potentiometers
(MAX5451/MAX5453/MAX5455), H_ is unconnected and L_ = GND. For the 2-terminal potentiometers
(MAX5450/MAX5452/MAX5454), L_ = GND. At 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. At VDD = +3V,
200A/40A/20A for 10k
/50k/100k configuration, respectively.
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: Device draws higher supply current when 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.)
Note 6: Wiper-Settling Time is the worst case 0% to 50% rise-time measured between consecutive wiper positions. 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).
Note 7: Digital timing is guaranteed by design.
ELECTRICAL CHARACTERISTICS (continued)
(VDD = +2.7V to +5.5V, VH = VDD, VL = 0; TA = TMIN to TMAX, unless otherwise noted. Typical values are at VDD = +5V, TA = +25°C,
unless otherwise noted.)
