Detailed Description
Each potentiometer consists of 255 fixed resistors in
series between pins HB and LB for the 3-terminal
potentiometer and between WA and LA for the 2-termi-
nal variable resistor (Figure 1). The potentiometer wiper
(pin WX) can be programmed to access any one of the
256 different tap points on the resistor string. The
MAX5403/MAX5404/MAX5405 require nine bits to pro-
gram the wiper position. The 1st bit is an address code,
allowing one or the other potentiometers to be selected
for programming. The potentiometers are programmed
independently of each other.
The MAX5403/MAX5404/MAX5405 use a 3-wire serial
data interface to control the wiper tap position. This
write-only interface contains three inputs: Chip Select
(CS), Data In (DIN), and Data Clock (SCLK). When CS
is taken low, data from the DIN pin is synchronously
loaded into the serial shift register on each rising edge
