Maxim Integrated DS1845X-010 Dual Digital Potentiometer with Memory

The DS1845X-010 from Maxim Integrated is a versatile, dual digital potentiometer device that incorporates nonvolatile memory to store user-defined presets. This precision potentiometer is designed to provide a reliable solution for applications requiring digital control of resistance settings. Its compact form factor and integrated features make it an ideal choice for a wide range of applications including calibration, signal conditioning, and power-supply adjustment.

Each potentiometer in the DS1845X-010 has a resistance value of 10kΩ and features 256-position wiper settings, allowing for fine-grained adjustments. The wiper position can be adjusted through an I2C-compatible serial interface, which enables easy integration into digital systems. Furthermore, the device can store multiple wiper positions in its onboard EEPROM, which preserves the settings even when the power is turned off, ensuring persistent performance across power cycles.

The DS1845X-010 is designed to operate over a wide voltage range of 2.7V to 5.5V, making it suitable for both 3.3V and 5V systems. Its robust design ensures reliable operation over the industrial temperature range of -40°C to +85°C. The dual potentiometer configuration allows for simultaneous control of two separate channels, which can be useful in stereo audio applications or in systems where dual control is required.

Key features of the DS1845X-010 include:

• 10kΩ resistance per potentiometer
