MCP42U83

MCP42U83 devices are 10-bit dual-channel digital potentiometers, having both volatile and nonvolatile MTP memory with 1,000 write cycles.

The features provided by MCP42U83 facilitate device integration into automotive and industrial applications.

MCP42U83 can have either a single-ended or a dual power supply without requiring any initial configuration. Configuring the operating mode in a dedicated register allows MCP42U83 to be used either as a potentiometer or as a rheostat (variable resistor). The internal resistor ladder has 1,023 resistors with 1,024 wiper connection points, from zero to full scale.

All three terminals (A, B and W) can be independently disconnected from the resistor ladder to reduce power consumption or to configure the part as a potentiometer or as a rheostat.
