ELECTRICAL CHARACTERISTICS (continued)

(VDD = VLOGIC = +2.7V to +5.5V, VSS = 0V, GND = 0V, VH_ = VDD, VL_ = VSS, TA = TMIN to TMAX. Typical values are at TA = +25°C,

unless otherwise specified.) (Note 1)

Note 1: Parameters are 100% production tested at +85°C and limits through temperature are guaranteed by design.

Note 2: Supply current measured with the supply on and a button pushed.

Note 3: Supply current measured with the power on, no button pushed, and the wiper position fixed.

Note 4: This is the measured current with SHDN low and MODE_IND unconnected.
