MCP4641T-502E/ML Integrated Circuits (ICs)

Data Acquisition - Digital Potentiometers

The MCP4641T-502E/ML is a digital potentiometer designed for Data Acquisition. It combines a 32-position 5 bit wiper setting with an SPI compatible serial interface and an integrated EEPROM memory. This makes it suitable for use in applications where precise control of resistance value is required. As one of the few ICs available with such functionality, the MCP4641T-502E/ML offers an economical solution to a wide range of data acquisition tasks.

The MCP4641T-502E/ML digital potentiometer consists of a five bit wiper and an integrated resistance element, along with its associated circuitry. This potentiometer is based on a non-volatile resistive element, which makes it ideal for applications where an accurate reference voltage is required. The potentiometer is designed to operate at a supply voltage of 5VDC and operates within the range of 4.5VDC-36VDC.

The device can be programmed through a SPI serial interface and includes an integrated EEPROM that stores the setting of the wiper. This allows the setting of the potentiometer to be stored in non-volatile memory and retrieved whenever required. The MCP4641T-502E/ML can be operated at a maximum switching frequency of 3Mz, which is suitable for most applications.

The wiper position can be adjusted using the SPI serial interface, which allows precise control of the position across all 32 steps. Additionally, the device includes a power-on reset functionality, which ensures that the device will reset to the stored setting upon power up. As an additional feature, the device also includes a mean offset trimming capability, which allows for precise adjustment of the reference voltage.

In terms of applications, the MCP4641T-502E/ML can be used in a variety of data acquisition tasks, such as measuring signals from sensors and other devices, monitoring processes and controlling various equipment elements. Additionally, the device can be used in automotive applications, where the precise control of voltage or resistance is required.

In summary, the MCP4641T-502E/ML is an ideal solution for any application requiring precise control of a resistive element. With its integrated EEPROM storing the wiper setting, the device is suitable for applications where an accurate and reliable reference voltage is required. Moreover, the device can also be used in automotive and other applications where precise voltage or resistance control is necessary.
