MCP4151 - 7/8-Bit Single/Dual SPI Digital POT

Download the MCP4151 datasheet PDF. This datasheet also covers the MCP4131 variant, as both devices belong to the same 7/8-bit single/dual spi digital pot family and are provided as variant models within a single manufacturer datasheet.

General Description

The MCP41XX and MCP42XX devices offer a wide range of product offerings using an SPI interface.

WiperLock Technology allows application-specific calibration settings to be secured in the EEPROM.

Key Features

  • Single or Dual Resistor Network options.
  • Potentiometer or Rheostat configuration options.
  • Resistor Network Resolution - 7-bit: 128 Resistors (129 Steps) - 8-bit: 256 Resistors (257 Steps).
  • RAB Resistances options of: - 5 kΩ - 10 kΩ - 50 kΩ - 100 kΩ.
  • Zero-Scale to Full-Scale Wiper operation.
  • Low Wiper Resistance: 75Ω (typical).
  • Low Tempco: - Absolute (Rheostat): 50 ppm typical (0°C to 70°C) - Ratiometric (Potentiometer): 15 ppm typic.
