Digital potentiometers are devices capable of providing adjustable resistance in electronic circuitry. The MCP4261-104E/ST is a digital potentiometer that is widely used in a variety of applications. It has a wide range of operating voltages and a low power requirement that makes it ideal for applications that require precise adjustment of resistance.

The MCP4261-104E/ST is an SPI-compatible (Serial Peripheral Interface) 8-bit digital potentiometer with a wiper range of 0 to 100-ohm in the linear BS (Broadcast Sweeps) range. The device includes an onboard register that stores the resistance value that the wiper is set to. This makes it ideal for applications in which the setting of the resistance value is not kept constant – such as in applications that require user input.

The MCP4261-104E/ST features internal EEPROM that allows for non-volatile storage of a user-defined resistance value. This means that the device can be used in applications that require frequent adjustment of resistance levels without the need to re-program the resistance values every time. The device also has an onboard shutoff feature that can be used to reduce power consumption or to prevent accidental adjustment of the wiper setting.

The MCP4261-104E/ST also has a wide operating temperature range, making it suitable for use in harsh environments. The device also typically has a longer life cycle than other digital potentiometers, and can be used in low power applications or where no power is present.

The MCP4261-104E/ST is primarily used in data acquisition applications, such as in optical, pressure and temperature sensing. Here, the device can be used to provide precise adjustment of resistance, allowing for the right level of sensitivity in the system. The device can also be used in consumer electronics, where the wide operating temperature range and low power consumption makes it ideal for use in portable devices.

The basic working principle of the MCP4261-104E/ST is the same as most other digital potentiometers. When a logic signal is supplied to the register, it reads the data stored in the register and adjusts the resistance between the device’s pins accordingly. This enables the device to provide adjustable resistance levels for different applications.

The MCP4261-104E/ST is a versatile and reliable digital potentiometer that is widely used for data acquisition and consumer electronics applications. Thanks to its wide range of operating voltages and its low power consumption, the device is ideal for use in applications that require precise adjustment of resistance levels.
