Data Acquisition – Digital Potentiometers consists of a range of electronically adjusted potentiometers that can be used to control the resistance value in an electronic circuit. MCP4352T-103E/ST is one of these digital potentiometers which can be used for various applications in the field of data acquisition.

This device is an 8-channel digital potentiometer with a resistance range of 305Ω to 10KΩ. It has a 3-wire SPI-compatible serial interface and 8 built-in memory registers for storing value. All operations can be controlled through the three pins of the serial interface. Additionally, the device can be reset to any user-specified value by means of the hardware reset pin. The MCP4352T-103E/ST device is designed to operate with supply voltage between 2.3V and 5.5V.

The MCP4352T-103E/ST digital potentiometer is used in various data acquisition applications like motion control, digital timing circuit or remote control. It can be used to adjust the frequency of digital signals, control the amplitude of analog signals and adjust the parameters of power supplies. It has wide range of applications including industrial measurement, automotive electronics and consumer electronics.

The working principle of MCP4352T-103E/ST digital potentiometer is based on the concept of electrical resistance. This device consists of two terminals, with one terminal connected to ground and another one connected to a voltage source. These terminals are connected to a wiper which moves across a resistor ladder. As the wiper moves, the resistance between the two terminals changes. The magnitude of the resistance is determined by the position of the wiper and is monitored by a microcontroller.

The microcontroller can be used to set the wiper to any desired position with the help of the SPI-compatible serial interface. The wiper can be instructed to move to the left or right, or to move a specific number of positions, or to move the maximum or minimum positions. The user can also reset the wiper position to a predetermined value.

The MCP4352T-103E/ST digital potentiometer is highly reliable and can be used in harsh applications, as it is designed to withstand static electricity and is able to operate at temperatures as low as -25°C and as high as 85°C.

In summary, the MCP4352T-103E/ST digital potentiometer is a highly reliable, low power device suitable for data acquisition applications. It has wide range of applications and is used for various functions like controlling the frequency of digital signals, adjusting the analog signals and adjusting the parameters of the power supplies. It is easy to use and can be programmed through SPI-compatible serial interface.
