X9252
Low Power + Quad 256-tap + 2-Wire Bus + Up/Down Interface
Quad Digitally-Controlled (XDCP)
Potentiometer
The X9252 integrates 4 digitally controlled potentiometers
(XDCP) on a monolithic CMOS integrated circuit.
The digitally controlled potentiometers are implemented
using 255 resistive elements in a series array. Between each
pair of elements are tap points connected to wiper terminals
through switches. The position of each wiper on the array is
controlled by the user through the Up/Down (U/D) or 2-wire
bus interface. The wiper of each potentiometer has an
associated volatile Wiper Counter Register (WCR) and four
non-volatile Data Registers (DRs) that can be directly written
to and read by the user. The contents of the WCR controls
the position of the wiper on the resistor array through the
switches. At power-up, the device recalls the contents of the
default data registers DR00, DR10, DR20, DR30, to the
corresponding WCR.
Each DCP can be used as a three-terminal potentiometer or
as a two terminal variable resistor in a wide variety of
applications including the programming of bias voltages, the
implementation of ladder networks, and three resistor
programmable networks.
