Microchip Technology, Inc. Digital Potentiometers MCP47DA1T-A0E/LT

The MCP47DA1T-A0E/LT is a 6-bit digital potentiometer featuring a buffered output and a 2-wire I²C interface for control. It supports two slave addresses (5Ch and 7Ch) and offers 65 taps, allowing for a wiper setting range from zero to full scale. The output voltage range is specified as -1/3 * VREF to 2/3 * VREF, with a typical VREF pull-down resistance of 30 kΩ. This device operates within a wide voltage range of 1.8V to 5.5V, with characteristics specified from 2.7V to 5.5V. It has a low static current consumption of approximately 100 µA and features brown-out reset protection at a typical threshold of 1.5V. The MCP47DA1T-A0E/LT is available in compact SOT-23-6 and SC70-6 packages, making it suitable for space-constrained applications. It is designed for use in various applications, including PC servers and mechanical trim potentiometer replacements. The device also operates over an extended temperature range of -40°C to +125°C, ensuring reliability in diverse environments.
