Product Description
Microchip MCP42100-I/ST digital potentiometer is a high-precision electronic component designed for adjustable resistance applications. Featuring 256 discrete resistance positions, it allows fine control over 100 kΩ resistance values in a dual-channel (2 pots per package) configuration. This device uses an SPI interface for seamless integration into digital systems, enabling easy programming and control.
Housed in a compact 14-pin TSSOP surface mount package, the device is suitable for space-constrained circuit designs. Its operating voltage range of 2.7V to 5.5V makes it compatible with a variety of low-voltage electronic circuits.
The digital potentiometer has a linear taper type and a temperature coefficient of 800 ppm/°C, ensuring stable performance across temperatures from -40°C to 85°C, typical of industrial environments.
The internal memory is volatile, meaning resistance settings reset when power is removed, suitable for systems requiring dynamic adjustment during operation.
At just 5.1mm x 4.5mm x 0.95mm, its small footprint saves board space in compact electronic assemblies. The device complies with RoHS directives, ensuring it meets environmental and safety standards.
