Data Acquisition - Digital Potentiometers

The MCP4132T-503E/SN is a digital potentiometer that can be utilized in a variety of applications to provide a low cost and variable gain solution. It consists of a 3-terminal chip containing a 256-position variable resistor which can be electronically controlled. This variable resistor has a resistance range of 2.02kΩ to 20kΩ and enables variable attenuation and signal amplitude control in a variety of applications.

Digital potentiometers can be used as digital gain-control devices for active filters, audio amplifiers, and speaker systems. The MCP4132T-503E/SN has built-in non-volatile memory to enable it to retain the last set position over a wide range of applications. This digital potentiometer can also be used as a reference divider for analog-to-digital converter (ADC) applications.

The MCP4132T-503E/SN is designed to be used in applications with supply voltage between 2.7V to 5.5V and operating temperature of -40°C to +85°C. In terms of features, this digital potentiometer includes a latch pin, write protect pin, SET pin, sense voltage pins, and a chip select (CS) pin. The chip disable input is active high, and the shutdown mode is deep sleep.

The latch pin on the MCP4132T-503E/SN provides the ability to write protect the register. The SET pin is used to program a known resistance value into the variable resistor. The sense voltage pins provide a variable output voltage that is proportional to the programmed resistance. The CS pin is used for communication with the digital potentiometer in order to set the resistance.

In terms of the working principle, the MCP4132T-503E/SN digital potentiometer functions as follows: A logic signal applied to the CS pin determines whether the microcontroller is selected for communication or not. The latch pin is used to write protect the resistance register of the digital potentiometer. An internal oscillator provides a signal to increment or decrement the stored resistance value based on the logic level of the SET pin. The resulting resistance is proportional to the voltage between the sense voltage pins.

The MCP4132T-503E/SN digital potentiometer is an ideal solution for providing linear and logarithmic gain control in audio applications. Built-in features, such as the latch and write protect pins, make this device an attractive choice for applications requiring reliable performance. In addition, this digital potentiometer can be used to provide an adjustable reference voltage to ADCs and control the output amplitude of audio amplifiers, making it suitable for a wide range of applications.
