DESCRIPTION
X9252
The X9252 integrates 4 digitally controlled potentio-
meters (XDCP) on a monolithic CMOS integrated
circuit.
The digitally controlled potentiometers are imple-
mented using 255 resistive elements in a series array.
Between each pair of elements are tap points con-
nected to wiper terminals through switches. The posi-
tion 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 writ-
ten to and read by the user. The contents of the WCR
controls the position of the wiper on the resistor array
though 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 potentio-
meter 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.
