AD5272BRMZ-100 is a data acquisition digital potentiometer. It is designed for use in applications requiring a precise digital control of the position of a user-defined resistor. It offers 2-byte digital resolution and is available in a variety of resistance and voltage ratings. The device features a 0.5 Ω to 100 Ω resistance range and works with ±3 to ±30 volts of applied power. It also features an I2C/SPI digital interface for programming and controlling the digital potentiometer.

The AD5272BRMZ-100 is capable of operating over the temperature range of -40℃ to +125℃. This makes it suitable for industrial, automotive and other harsh environments. It is available in SOT23-5 and Micro SMD packages. It is highly reliable, with a life expectancy of over one million cycles. Additionally, it is EMI/ESD aware and offers ESD performance up to 15 kV.

The AD5272BRMZ-100 is a two-channel digital potentiometer. The two channels are configured by setting the logic voltage at VREF to a high or low value. The device is controlled by writing a 2-byte digital word to the I2C/SPI digital interface. A 10-bit resolution is achieved by sending 0 (low voltage) or 1 (high voltage) to the digital pins. Each of the channels is adjustable up to a full 90° rotation, allowing for precise control of the applied voltage. The current drawn is only 1.5mA which makes it ideal for use in low-power applications.

The AD5272BRMZ-100 also features built-in OTP (One Time Programmable) memory which can be used to store configuration information or other user-defined settings. This eliminates the need for reprogramming with each power-up cycle. The device also includes a haptic feedback feature which allows the user to feel when the programmed voltage has been activated. This is especially useful in applications which require a precise voltage setting.

The AD5272BRMZ-100 is widely used in applications such as motor speed control, flow control, data acquisition, and industrial automation. When used in data acquisition, the device can be used to control the position of a user-defined resistor accurately and precisely. It is also widely used for controlling the speed of motors in industrial and automotive applications. Additionally, the device can be used for precise voltage adjustment in AC/DC power supplies.

In summary, the AD5272BRMZ-100 is a two-channel digital potentiometer with 0.5 Ω to 100 Ω resistance range and ±3 to ±30 volts of applied power. It features a 10-bit resolution, I2C/SPI digital interface, and OTP memory. It offers EMI/ESD protection and is capable of operating over the temperature range of -40℃ to +125℃. The device can be used in applications such as motor speed control, flow control, data acquisition and industrial automation.
