PRINCIPLES OF OPERATION
The X9269 is a integrated microcircuit incorporating
four resistor arrays and their associated registers and
counters and the serial interface logic providing direct
communication between the host and the digitally
controlled potentiometers. This section provides detail
description of the following:
– Resistor Array Description
– Serial Interface Description
– Instruction and Register Description.
Array Description
The X9269 is comprised of a resistor array (See Figure
1). Each array contains 255 discrete resistive segments
that are connected in series. The physical ends of each
array are equivalent to the fixed terminals of a
mechanical potentiometer (RH and RL inputs).
At both ends of each array and between each resistor
segment is a CMOS switch connected to the wiper
(RW) output. Within each individual array only one
switch may be turned on at a time.
These switches are controlled by a Wiper Counter
Register (WCR). The 8-bits of the WCR (WCR[7:0])
are decoded to select, and enable, one of 256
switches (See Table 1).
The WCR may be written directly. These Data
Registers can the WCR can be read and written by the
host system.
Power-up and Down Requirements.
There are no restrictions on the power-up or power-
down conditions of VCC and the voltages applied to
the potentiometer pins provided that VCC is always
more positive than or equal to VH, VL, and VW, i.e.,
VCC ≥ VH, VL, VW. The VCC ramp rate specification is
always in effect.
