MAX5490TA0500+ – MAXIM INTEGRATED

The Maxim Integrated MAX5490TA0500+ is a precision, digitally adjustable, nonvolatile resistor with a 5kΩ end-to-end resistance value. This device offers 32 wiper positions controlled via a simple 3-wire SPI interface, allowing for precise resistance trimming and gain adjustment. The MAX5490TA0500+ features an output voltage rating of 15V and an output current rating of 25mA. Its nonvolatile memory ensures that the wiper position is retained even after power-down, making it ideal for applications requiring stable, pre-set resistance values. The device is available in a compact 14-pin TSSOP SMD package, enabling high-density board designs. This part operates across a wide –40°C to 125°C operating temperature range, making it suitable for harsh environments. Common use cases include gain setting in amplifiers, programmable voltage dividers, and sensor calibration. Its digital interface significantly simplifies calibration procedures compared to manual potentiometers.
