AD5170BRMZ10

AD5170BRMZ10 Description

The AD5170BRMZ10 from Analog Devices Inc. is a 10kΩ digital potentiometer with 256-tap resolution, designed for precision analog adjustment in modern electronic systems. It operates over a 2.7V to 5.5V supply range and features a low temperature coefficient of 35ppm/°C, ensuring stable performance across varying environmental conditions. The device integrates a One-Time Programmable (OTP) memory, allowing permanent wiper position storage for reliable system calibration. Its I2C-compatible interface supports selectable addressing, enabling multiple devices on a single bus. Packaged in a compact 10MSOP, it is ideal for space-constrained applications.

AD5170BRMZ10 Features

• 256-tap resolution for fine-grained resistance adjustment.
• OTP memory for non-volatile wiper storage, eliminating recalibration needs.
• ±20% tolerance and 160Ω typical wiper resistance for consistent performance.
• I2C interface with selectable addressing (supports up to four devices on one bus).
• Low 35ppm/°C tempco ensures minimal drift over temperature.
• RoHS3 compliant and REACH unaffected, meeting environmental standards.
• Surface-mount 10MSOP package for high-density PCB designs.

AD5170BRMZ10 Applications
