Description
The MCP41XX and MCP42XX devices offer a wide range of product offerings that use an SPI interface. This family of devices supports 7-bit and 8-bit resistor networks, as well as potentiometer and rheostat pinouts.

Features
• One/two resistor network
options • Potentiometer or rheostat configuration options
• Resistor network resolution
– 7-bit: 128 resistors (129 steps)
– 8-bit: 256 resistors (257 steps)
• Wiper operation from zero scale to full scale Scale
• Low Wiper Resistance: 75O (typical)
• Low Tempco:
– Absolute (Rheostat): 50 ppm typical (0°C to 70°C)
– Ratiometric (potentiometer): 15ppm typical
• Serial SPI interface (10MHz, modes 0.0 & 1.1)
