**AD5200BRMZ10-REEL7 Digital Potentiometer: Key Features, Applications, and Technical Specifications**

The AD5200BRMZ10-REEL7 from Analog Devices is a single-channel, **digitally programmable potentiometer** (digipot) designed to replace traditional mechanical potentiometers in a wide array of electronic circuits. This integrated circuit offers precise resistance control through a digital interface, enabling automation, remote adjustment, and enhanced reliability in modern electronic designs.

**Key Features**

The AD5200 stands out due to its combination of simplicity and performance. Its most notable features include:

* **10 kΩ Nominal Resistance:** The `10` in the part number denotes a fixed end-to-end resistance of 10 kΩ, a common value for many signal conditioning and tuning applications.

* **256-Position Resolution:** It provides **256 taps** or settable positions, allowing for fine-grained adjustment of the resistance value with a step change of approximately 39 Ω.

* **Simple 3-Wire SPI-Compatible Interface:** The device is controlled via a straightforward serial peripheral interface (SPI), making it easy to interface with microcontrollers, DSPs, and other digital logic.

* **Compact MSOP-10 Package:** Housed in a space-saving **10-lead MSOP** package, it is ideal for high-density PCB layouts and portable equipment.

* **Single-Supply Operation:** It operates on a wide single-supply voltage range from **2.7 V to 5.5 V**, making it suitable for both 3.3 V and 5 V systems.

* **Non-Volatile Memory (NV) Not Included:** It is important to note that the AD5200 is a volatile digipot. The wiper position resets to a mid-scale default upon power-up unless saved by an external controller.

**Applications**

The versatility of the AD5200BRMZ10-REEL7 allows it to be used in numerous applications, including:

* **Programmable Voltage Regulation:** Used to adjust the output of power supplies or voltage references.

* **LCD Screen Contrast and Brightness Control:** Replacing mechanical pots for on-screen display settings in consumer and industrial equipment.

* **Sensor Calibration and Trimming:** Providing automatic or remote calibration for bridge sensors and other precision measurement systems.

* **Audio Equipment:** Implementing volume control and tone adjustment in professional and automotive audio systems.

* **Optical Module Adjustment:** Fine-tuning bias currents and modulation amplitudes in fiber optic transceivers.
