Features & Applications

The MCP41/42XX series of devices are non-volatile, 7-bit (129 wiper steps) digital potentiometers that are programmed/reprogrammed through an SPI compatible interface.

The MCP41/42XX devices offer a variety of configurations simplifying design while minimizing cost, package size and pin count. The MCP41/42XX family of devices are available with resistor values of 5 K?, 10 K?, 50 k and 100 K?.

Features:

  • 256 taps for each potentiometer
  • 7-bit: 128 Resistors with Taps to VSS and VDD
  • SPI compatible interace
  • Automatic Recall of Potentiometer Wiper Settings
  • Resistance Values: 5 kΩ, 10 kΩ, 50 kΩ, 100 kΩ
  • Low Tempco:
    • Absolute (Rheostat): <100 ppm (typ.)
    • Ratiometric (Potentiometer): <10 ppm (typ.)
  • Low Wiper Resistance: 100 Ω (typ.)
  • Low-Power Operation: 1 μA Max Static Current
  • Wide Operating Voltage: 1.8 V to 5.5 V
  • Extended Temperature Range: -40°C to +125°C

Applications:

  • Audio equipment (volume and tone controls)
  • Servo-motor control
  • Battery charging and control
  • Communications (line impedance matching)
  • Power supplies
  • Instrumentation (gain, offset adjust)
  • LCD contrast control and programmable filters
