The DS1866Z/T&R is an IC (Integrated Circuit) component manufactured by Maxim Integrated. It is a versatile digital potentiometer that combines a nonvolatile memory, digital-to-analog converters (DACs), and a microcontroller unit (MCU) into a single chip.
Key features of the DS1866Z/T&R include:
1. Nonvolatile memory: The IC incorporates EEPROM (Electrically Erasable Programmable Read-Only Memory) to store and retain settings even when the power is turned off. This ensures that the device's configurations are preserved over multiple power cycles.
2. Dual digital potentiometers: The DS1866Z/T&R includes two programmable potentiometers, each with a resolution of 256 steps. These potentiometers can be used to adjust analog voltage levels in various applications, such as audio volume control or bias voltage adjustment.
3. I2C interface: The IC utilizes the I2C (Inter-Integrated Circuit) communication protocol, allowing easy interfacing with a wide range of microcontrollers and other digital devices. This enables seamless integration into larger systems.
4. Standalone operation: The DS1866Z/T&R can be used without an external microcontroller. It incorporates a built-in MCU that allows setting, control, and monitoring of potentiometers through its I2C interface. This standalone operation mode simplifies the implementation of digital potentiometer functionality
