The MAX543ACPA is an integrated circuit (IC) component that belongs to the MAX543 series of digitally-controlled potentiometers manufactured by Maxim Integrated. This device is a dual, 256-tap, nonvolatile digital potentiometer, which offers various advantageous features for electronic applications.
One of the key features of the MAX543ACPA is its dual-channel configuration, which means it contains two independent potentiometers within a single IC package. Each channel consists of a resistor array, wiper switches, and control registers, allowing individual control and adjustment of two different signals or parameters in a circuit. This dual-channel capability provides flexibility and simplifies circuit design, reducing the need for multiple components.
The MAX543ACPA is also known for its high resolution, offering 256 digitally selectable tap points. This enables precise and accurate adjustments, making it suitable for applications requiring fine-tuning or calibration. The device utilizes a 10-bit digital-to-analog converter (DAC) to control the resistance ratio of each potentiometer, ensuring smooth and continuous adjustments.
Another notable feature of the MAX543ACPA is its nonvolatile memory. This means that the device can retain its settings even when power is removed or turned off. This feature ensures that the potentiometer settings are preserved, eliminating the need for reprogramming upon power cycling. The nonvolatile memory also enhances reliability and ease of use in applications where settings need to be stored and recalled
