DESCRIPTION
The Xicor X9015 is a 32 tap potentiometer that is volatile.
The device consists of a string of 31 resistors that can be
programmed to connect the RW/VW wiper output with
any of the nodes between the connecting resistors. The
connection point of the wiper is determined by
information communicated to the device on the 3-wire
port. The 3-wire port changes the tap position by a falling
edge on the increment pin. Direction the wiper moves is
determined by the state of the Up/Down pin. The wiper
position at power up is tap #15.
The X9015 can be used in a wide variety of applications
that require a digitally controlled variable resistor to set
analog values.

*COMMENT
Stresses above those listed under “Absolute Maximum
Ratings” may cause permanent damage to the device.
This is a stress rating only and the functional operation of
the device at these or any other conditions above those
listed in the operational sections of this specification is
not implied. Exposure to absolute maximum rating condi-
tions for extended periods may affect device reliability.

See circuit #3
Notes:
(1) Absolute Linearity is utilized to determine actual wiper voltage versus expected voltage
= (Vw(n)(actual) – Vw(n)(expected)) = ±1 Ml Maximum.
(2) Relative Linearity is a measure of the error in step size between taps = VW(n+1) – [Vw(n) + Ml] = ±0.2 Ml.
(3) 1 Ml = Minimum Increment = RTOT/31.
(4) Typical values are for TA = 25°C and nominal supply voltage.
(5) This parameter is periodically sampled and not 100% tested.
