Single Volatile 32-Tap XDCP™
October 7, 2005
FN8225.3
Digitally Controlled Potentiometer (XDCP)
The Intersil ISL90460 is a digitally controlled potentiometer
(XDCP). Configured as a variable resistor, the device
consists of a resistor array, wiper switches, a control section,
and volatile memory. The wiper position is controlled by a
2-pin Up/Down interface.
The potentiometer is implemented by a resistor array
composed of 31 resistive elements and a wiper switching
network. Between each element and at either end are tap
points accessible to the wiper terminal. The position of the
wiper element is controlled by the CS and U/D inputs.
The device can be used in a wide variety of applications
including:
• LCD contrast control
• Parameter and bias adjustments
• Industrial and automotive control
• Transducer adjustment of pressure, temperature, position,
chemical, and optical sensors
• Laser Diode driver biasing
• Gain control and offset adjustment
Features
• Volatile Solid-State Potentiometer
• 2-pin UP/DN Interface
• DCP Terminal Voltage, 2.7V to 5.5V
• Tempco 35ppm/°C Typical
• 32 Wiper Tap Points
• Low Power CMOS
- Active current 25µA max.
- Supply current 0.3µA
• Available RTOTAL Values = 10kΩ, 50kΩ, 100k
• Temp Range -40°C to +85°C
• Packages
- 5 Ld SC-70, SOT-23

NOTE: Intersil Pb-free plus anneal products employ special Pb-free material sets; molding compounds/die attach materials and 100% matte tin plate termination finish, which are
RoHS compliant and compatible with both SnPb and Pb-free soldering operations. Intersil Pb-free products are MSL classified at Pb-free peak reflow temperatures that meet or exceed
the Pb-free requirements of IPC/JEDEC J STD-020.

NOTES:
1. Absolute linearity is utilized to determine actual wiper voltage versus expected voltage = (RH(n)(actual) - RH(n)(expected)) = ±1 Ml Maximum.
n = 1 .. 29 only.
2. Relative linearity is a measure of the error in step size between taps = RH(n+1) - [RH(n) + Ml] = ±0.5 Ml, n = 1 .. 29 only.
3. 1 Ml = Minimum Increment = RTOT/31.
4. Typical values are for TA = 25°C and nominal supply voltage.
