DesCrIPTIOn
CAT50/58/59/523/524/525 linear-taper
digitally programmable potentiometers perform the same
function as a mechanical potentiometer or a variable
resistor. These devices consist of a fixed resistor and
a wiper contact with 32-tap points that are digitally
controlled through a 2-wire up/down serial interface.
The CAT5110 and CAT5125 are configured as poten-
tiometers. The CAT5118/19/23/24 are configured as
variable resistors.
Three resistance values are available: 10kΩ, 50kΩ and
100kΩ. All devices are available in space-saving 5-pin
and 6-pin SOT-23 packages. The CAT50/58/59
are also available in the SC70 package.
