Detailed Description
The MAX5481/MAX5482 linear programmable voltage-
dividers and the MAX5483/MAX5484 variable resistors
feature 1024 tap points (10-bit resolution) (see the
Functional Diagrams
). These devices consist of multi-
ple strings of equal resistor segments with a wiper con-
tact that moves among the 1024 points through a
pin-selectable 3-wire SPI-compatible serial interface or
up/down interface. The MAX5481/MAX5483 provide a
total end-to-end resistance of 10k
, and the
MAX5482/MAX5484 have an end-to-end resistance of
50k
. The MAX5481/MAX5482 allow access to the
high, low, and wiper terminals for a standard voltage-
divider configuration.
MAX5481/MAX5482 Programmable
Voltage-Dividers
The MAX5481/MAX5482 programmable voltage-
dividers provide a weighted average of the voltage
between the H and L inputs at the W output. Both
devices feature 10-bit resolution and provide up to
1024 tap points between the H and L voltages. Ideally,
the V
L
voltage occurs at the wiper terminal (W) when all
data bits are zero and the V
H
voltage occurs at the
wiper terminal when all data bits are one. The step size
(1 LSB) voltage is equal to the voltage applied across
terminals H and L divided by 2
10
. Calculate the wiper
voltage V
