The WMS7170050M is a precision digital potentiometer designed for applications where a high degree of accuracy, resolution and stability is required. It is a single-turn, 10k-ohm device with a resistance range of 10k ohms. The device features a user-programmable resolution of 1 bit step with an accuracy of 1% over its full temperature range. The WMS7170050M is an ideal choice for applications that require a very precise control of the output voltage or current. It can also be used to measure electrical parameters such as voltage, current and resistance.

The WMS7170050M features an integrated 24-bits Digital-to-Analog Converter (DAC) that can be programmed with a data command to provide a precise voltage or current output. The potentiometer’s resistance range can be adjusted using a digital word to control the bias voltage of the integrated R2R ladder network. The user interface can be configured to operate at 5V or 3.3V voltage levels.

The device offers a wide range of programming options such as multi-bit (up to 24-bit) resolution and adjustable gain. The integrated 24-bit DAC makes it easy to configure the device within a range of processing options such as linear interpolation, logarithmic interpolation, pulse width modulation, and more. It also offers a sampling rate of up to 400kHz for fast data processing. It supports various communication interfaces, such as I2C, I2S, RS232, SPI and other digital signal formats.

The WMS7170050M is suitable for a wide range of applications, such as motor drives, industrial automation, and medical device control. It is well-suited for applications requiring precise positioning control, such as CNC milling machines, robotic systems, and camera positioning systems. Additionally, it can be used to provide precise signal conditioning for analog-to-digital converters and analog filters.

In terms of working principle, the WMS7170050M operates in an on-demand capacity, meaning that the current output is determined by the user’s programming instructions. The device features an internal oscillator that is used to generate the reference frequency, which is then used in synchronizing the digital-to-analog conversion (DAC). The DAC sets the output voltage of the device according to the programmed data. The DAC also controls the resistance range of the device. The adjustment of the resistance range is done by the user through programming the digital word.

Overall, the WMS7170050M is an ideal choice for applications requiring precise and accurate control of voltage or current. The device offers high accuracy, resolution, and stability and supports various communication interfaces and programming options. Furthermore, the device is well-suited for a wide range of applications and is designed for robust operation in extreme environments.
