The N57L5125 linear-taper digital POT performs 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 kΩ, 50 kΩ and 100 kΩ.

• 0.3 µA 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 kΩ, 50 kΩ and 100 kΩ
