MAX5471/MAX5472/MAX5474/MAX5475
32-Tap, Nonvolatile, Linear-Taper Digital
Potentiometers in SOT23
_______________________________________________________________________________________
3
Note 1: All devices are production tested at TA = +25°C and are guaranteed by design and characterization for -40°C < TA < +85°C.
Note 2: The DNL and INL are measured with the potentiometer configured as a variable resistor. For the 3-terminal potentiometers
(MAX5474/MAX5475), H is unconnected and L = GND. At VDD = 5.25V, W is driven with a source current of 80A for the
50k
Ω configuration, and 40A for the 100kΩ configuration. At VDD = 2.7V, the wiper terminal is driven with a source current
of 40A for the 50k
Ω configuration, and 20A for the 100kΩ configuration.
Note 3: The DNL and INL are measured with the potentiometer configured as a voltage-divider with H = VDD and L = GND
(MAX5474/MAX5475 only). The wiper terminal is unloaded.
Note 4: The wiper resistance is the worst value measured by injecting the currents given in Note 2 into W with L = GND.
RW = (VW - VH) / IW.
Note 5: The device draws higher supply current when digital inputs are driven with voltages between 0.3V x VDD and 0.7 x VDD.
Drive the digital inputs as close as possible to VDD or GND. (See the Typical Operating Characteristics for the Supply
Current vs. Digital Input Voltage graph.)
Note 6: Wiper at midscale with a 10pF load.
Note 7: Digital timing is guaranteed by design and characterization, and is not production tested.
Note 8: 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 the Typical Operating
Characteristics for the Tap-to-Tap Switching Transient).
Note 9: Digital inputs CS, U/D, and INC are connected to GND or VDD. See the Typical Operating Characteristics for the Static
Supply Current vs. Temperature graph.
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)
