The Microchip MCP4462-103E/ST is a digitally programmable potentiometer used in data acquisition systems. The device consists of a 32-position monotonic digital potentiometer and two independent 8-bit non-volatile registers (wiper settings). The device utilizes a memory register to store the potentiometer wipers settings, so that any configurable resistance setting can be quickly recalled as required. This data acquisition technology is an excellent solution for various applications, such as filtering, signal gating, gain controls, calibration, and many more.

The MCP4462-103E/ST features a low-voltage dual control interface for easy access. This interface allows for the user to read the wiper settings of the programmable potentiometer, allowing for the gains and offsets to be adjusted without relying on a physical potentiometer. The device also offers a power-down feature for further flexibility in power consumption.

In terms of operation, the MCP4462-103E/ST features a three-wire SPI/I2C interface and an on-chip 10kΩ minimum resistance between the pot terminals. This single-channel device provides a resistance range of 0 ohms to 10k ohms. The on-chip control registers are updated in a continuous fashion and these registers can be read and programmed. In terms of power consumption, the device runs off a single 3V to 5.5V source and only consumes 400µA of current during operation.

The MCP4462-103E/ST is ideal for signal processing applications such as filtering, signal gating, and gain control. It can also be used for calibration, providing a reliable and cost-effective solution for changing signal settings in a system. The device is also a great choice for applications in the automotive, medical, industrial, and communications fields.

At the core of the device lies a 10-bit ADC and a 10-bit DAC. This allows the user to adjust the wiper positions from 0Ω to 10kΩ by setting the amount of voltage or current to the pot terminals. The user can also register the settings of the programmable potentiometer, allowing for a faster recall of these settings in the future. Furthermore, the device has the ability to store up to 8 unique settings in the non-volatile memory, so that any configuration with the device can be easily recalled as needed.

In summary, the MCP4462-103E/ST is an ideal choice for data acquisition, signal processing, and calibration applications. Its low voltage dual control interface enables easy access and allows for the user to program and read the wiper settings. In addition, the device features non-volatile memory for storing settings, making it ideal for applications requiring frequent changes in gains, offsets, or other parameters. The device consumes low amounts of current as compared to other potentiometers and, as such, is a good fit for applications that require low power operation.
