Detailed Description
The MAX5400/MAX5401 consists of 255 fixed resistors
in series between pins H and L. The potentiometer
wiper (pin W) can be programmed to access any one
of the 256 different tap points on the resistor string. The
MAX5400/MAX5401 uses a 3-wire serial data interface
to control the wiper tap position. This write-only inter-
face 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
8-bit serial shift register on the rising edge of each
SCLK pulse. The MSB is shifted in first as shown in
Figure 4. Note that if
CS is not kept low during the entire
data stream, the data will be corrupted and the device
will need to be reloaded. After all 8 data bits have been
loaded into the shift register, they are latched into the
decoder once
CS is taken high. The decoder switches
the potentiometer wiper to the tap position that corre-
sponds to the 8-bit input data. Each resistor cell is
50k
/255 or 196.1 for the MAX5400 and 100k/255
or 392.2
for the MAX5401.
The MAX5400/MAX5401 feature power-on reset (POR)
circuitry that sets the wiper to the midscale position at
power-up by loading a binary value of 128 into the 8-bit
latch.
The MAX5400/MAX5401 can be used as a variable
resistor by connecting pin W to either pin H or pin L.
