32-Tap FleaPoT™, 2-Wire Digital
Potentiometers
General Description
Features
The MAX5460–MAX5468 linear-taper digital potentiome-
ters perform the same function as a mechanical poten-
tiometer 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 serial interface.
♦ Miniature SC70 and SOT23 Packages
♦ 0.3µA Ultra-Low Supply Current
♦ +2.7V to +5.5V Single-Supply Operation
♦ Glitchless Switching Between Resistor Taps
♦ Power-On Reset to Midscale
The MAX5462/MAX5465/MAX5468 are configured as
potentiometers. The rest of the devices in this family are
configured as variable resistors. See Pin Configurations
for part functionality.
♦ 2-Wire Up/Down Serial Interface
♦ 10kΩ, 50kΩ, and 100kΩ Resistance Values
Three resistance values are available: 10kΩ (MAX5466/
MAX5467/MAX5468), 50kΩ (MAX5463/MAX5464/
MAX5465), and 100kΩ (MAX5460/MAX5461/MAX5462).
The MAX5460–MAX5465 (100kΩ and 50kΩ) are avail-
able in space-saving 5-pin and 6-pin SC70 packages.
The MAX5466/MAX5467/MAX5468 (10kΩ) are available
in 5-pin and 6-pin SOT23 packages.
