The SPI interface allows direct connection to a microcontroller for wiper position control, making it suitable for volume control, signal scaling, and programmable gain stages. Each channel has a nominal resistance of 10kΩ with a wiper resistance of 250Ω typical. The ±25% tolerance on the end-to-end resistance is typical for digital potentiometers and should be accounted for in the circuit design where absolute accuracy matters. ## Temperature range and drift for industrial use The temperature coefficient of 35ppm/°C means the resistance drifts by only 0.35Ω per °C on a 10kΩ element, which is low enough for most precision analog circuits. For a 50°C swing, that is about 17.5Ω of drift — negligible in many gain-setting applications. The volatile memory type means the wiper position resets to midscale on power-up, so the system must initialize the wiper after each power cycle. ## Package and compliance The package is delivered in tube packaging. For volume production, confirm the tube quantity with your distributor at quote time.","metaTitle":"MAX5388LAUB+ Digital Potentiometer, 10kΩ, 256 Taps, SPI","metaDescription":"Analog Devices MAX5388LAUB+ digital potentiometer, 10kΩ, 256 taps, SPI, linear taper, -40°C to 125°C, 10-uMAX.
