MCP40D19T-103E/LT Description

Short technical summary and product information.

The Microchip Technology MCP40D19T-103E/LT is a 7-bit digital potentiometer offering 128 discrete resistance steps. It is configurable as a rheostat with a nominal resistance of 10kΩ and a tolerance of ±20%. The device utilizes an I2C serial interface for control and operates from a wide voltage range of 1.8V to 5.5V.

 

Designed for applications requiring precise voltage or gain control, this digital potentiometer is suitable for set point trimming, sensor calibration, and amplifier gain adjustment. It features low static current consumption of 2.5 µA typical and a wide operating temperature range of -40°C to +125°C. The low wiper resistance of 100 Ω typical and a linear taper are beneficial for signal integrity.

 

The MCP40D19T-103E/LT comes in a compact SC-70-5 surface-mount package, making it ideal for space-constrained designs. It also includes brown-out reset protection and a power-on default wiper setting at mid-scale.
