32‐tap Digital
Potentiometers (POTs)
with 2‐wire Interface
Description
N57L5125 linear-taper digital POTs perform the same function as a
mechanical potentiometer or a variable resistor. This device consists
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 N57L5125 is configured as a potentiometer. Three resistance
values are available: 10 kW, 50 kW and 100 kW. All devices are
available in a space-saving 6-pin SOT−23 package.
Features
0.3 mA Ultra-low Standby Current
Single-supply Operation: 2.7 V to 5.5 V
Glitchless Switching between Resistor Taps
Power-on Reset to Midscale
2-wire Up/Down Serial Interface
Resistance Values: 10 kW, 50 kW and 100 kW
Low Wiper Resistance: 80 W
These Devices are Pb-Free, Halogen Free/BFR Free and are RoHS
Compliant
Applications
LCD Screen Adjustment
Volume Control
Mechanical Potentiometer Replacement
Gain Adjustment
Line Impedance Matching

position.
4 CS Chip Select Input. A high-to-low CS transition determines the mode: increment if U/D is high, or
decrement if U/D
is low.
