Each of the two potentiometer circuits presents a 10kΩ end-to-end resistance with a wiper resistance of 1000 Ω typical. The logarithmic taper is the key differentiator here — it tracks the human ear's logarithmic response to sound pressure, so this part is built for audio volume control, not for linear gain-setting or voltage division where a linear-taper pot would be a better fit. Communication is over an SPI interface, and the wiper position is volatile — it resets to midscale on power-up. The operating supply range is 2.7 V to 3.6 V, and the part is rated over the industrial temperature range of -40°C to +85°C. ## Mute and zero-cross sense — the audio-specific features The part includes a mute function and a zero-cross sense feature. The zero-cross sense synchronises wiper transitions to the AC zero-crossing of the audio signal, which suppresses the audible pop and click that otherwise occurs when the wiper moves to a new tap. ## 32 taps and ±30% tolerance — resolution and absolute accuracy With 32 taps, the wiper can be set to 32 discrete positions between ground and the reference voltage. The ±30% tolerance on the absolute resistance (10 kΩ) is typical for digital potentiometers. ## Lifecycle and sourcing No last-time-buy or obsolescence notice is in effect.","metaTitle":"MAX5408ETE+ Digital Potentiometer, 32-Tap Logarithmic, SPI","metaDescription":"MAX5408ETE+ 10kΩ dual digital pot with logarithmic taper, 32 taps, SPI interface, mute & zero-cross sense.
