Wiper is not connected. I
AB
= 350µA for the 10kΩ version and 175µA for the 20kΩ version.
All Tempcos are guaranteed by design and not subject to production test.
Terminal A is not connected. I
W
= 350µA for the 10kΩ version and 175µA for the 20kΩ version.
Resistor terminals A, B, W have no limitations on polarity with respect to each other.
All capacitances are guaranteed by design and not subject to production test. Resistor-terminal capacitance
tests are measured with 2.5V bias on the measured terminal. The remaining resistor terminals are left open cir-
cuit.
7. Worst-case supply current consumed when input logic level at 2.4V, standard characteristic of CMOS logic.

DISS
is calculated from (I

CC
). CMOS logic level inputs result in minimum power dissipation.
9. All dynamic characteristics are guaranteed by design and not subject to production test. All dynamic characteris-
tics use V
