Detailed Description
Each potentiometer consists of 255 fixed resistors in
series between pins H
X
and L
X
(Figure 1). The poten-
tiometer wiper (pin W
X
) can be programmed to access
any one of the 256 different tap points on the resistor
string. The MAX5413/MAX5414/MAX5415 require nine
bits to program the wiper position. The first bit is an
address code, allowing one or the other potentiometer
to be selected for programming. The potentiometers
are programmed independently of each other.
The MAX5413/MAX5414/MAX5415 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
of each SCLK pulse (Figure 2). After all the data bits
