Figure 1. Voltage-Divider and Variable Resistor Configurations
Typical Operating Characteristics
(VDD = 5V, TA = +25°C, unless otherwise noted.)
Note 5: Drive HA with a 1kHz GND to VDD amplitude tone. LA = LB = GND. No load. WB is at midscale with a 10pF load.
Measure WB.
Note 6: The 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 loaded with 10pF capacitance to ground.
Note 7: Digital timing is guaranteed by design and characterization, not production tested.
Note 8: The SCL clock period includes rise and fall times (tR = tF). All digital input signals are specified with tR = tF = 2ns and
timed from a voltage level of (VIL + VIH)/2.
