One-Time Programmable, Linear-Taper
Digital Potentiometers
ELECTRICAL CHARACTERISTICS (continued)
(VDD = 2.7V to 5.5V, VPP = GND, 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)

Note 1: All devices are production tested at TA = +25°C and are guaranteed by design for TA = -40°C to +85°C.
Note 2: Digital timing is guaranteed by design, not production tested.
Note 3: Power-up time is the period of time from when the power supply is applied until the serial interface is ready for writing.
Note 4: Digital inputs CS and U/D are connected to GND or VDD.
