Dual 100k digital pot with I²C control
The MAX5392NAUE+ is a dual-channel, 100kΩ digital potentiometer from Analog Devices, configured as a linear-taper potentiometer with 256 wiper tap positions per channel. It communicates over an I²C interface, with a selectable address feature that allows up to four devices on the same bus. The volatile memory type means the wiper position resets to midscale on power-up and must be re-programmed after each power cycle.
Housed in a 16-TSSOP package (4.40mm width, 0.173" body), the MAX5392NAUE+ uses a standard 0.65mm pitch footprint that places cleanly with no tombstoning risk on a typical reflow profile. The wiper resistance is specified at 200Ω maximum — this adds a series offset that matters when the pot is used as a voltage divider in a precision attenuator, less so when used as a variable resistor in a bias or gain-setting circuit. The ±25% resistance tolerance means the absolute end-to-end resistance can vary from 75kΩ to 125kΩ across devices; the ratio matching between the two channels is tighter but not specified in this data set.
It is ROHS3 compliant, with no restricted substances above the threshold limits per EU Directive 2015/863.
