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

FUNCTIONAL DESCRIPTION
The N57L5125 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. Three end-to-end
resistance values are available: 10 kW, 50 kW and 100 kW.
The N57L5125 is designed to operate as a potentiometer.
In this configuration, the low terminal of the resistor array
is connected to ground (pin 2).
Digital Interface Operation
The devices have two modes of operation when the serial
interface is active: increment and decrement mode. The
serial interface is only active when CS is low.
The CS and U/D inputs control the position of the wiper
along the resistor array. When CS transitions from high to
low, the part will go into increment mode if U/D input is
high, and into decrement mode when U/D input is low. Once
the mode is set, the device will remain in that mode until CS
goes high again. A low-to-high transition at the U/D pin will
increment or decrement the wiper position depending on the
current mode (Figures 5 and 6).
When the CS input transitions to high (serial interface
inactive), the value of the counter is stored and the wiper
position is maintained.
Note that when the wiper reaches the maximum (or
minimum) tap position, the wiper will not wrap around to the
minimum (or maximum) position.
Power-On Reset
All parts in this family feature power-on reset (POR)
circuitry that sets the wiper position to midscale at
power-up. By default, the chip is in the increment mode.
