DS1848E-010+ — dual 10kΩ digital rheostat with non-volatile wiper storage
The Maxim Integrated DS1848E-010+ is a dual-channel digital potentiometer configured as a rheostat, offering 256 wiper positions per channel on a 10kΩ element with a linear taper. The wiper setting is stored in non-volatile memory, so the part powers up at the last programmed position — no microcontroller re-initialization needed after a reset. Communication is over the I²C bus, and the part includes a selectable address feature and an integrated temperature sensor. It is supplied in a 14-TSSOP surface-mount package and rated for the industrial temperature range of -40°C to 95°C, making it a fit for outdoor telecom, factory automation, and power-supply trimming loops that must hold calibration through power loss.
Lifecycle and compliance
No last-time-buy or obsolescence notice is in effect. For volume or scheduled orders, availability and pricing are confirmed at quote time through independent distribution — the part is sourced to order, not sitting on a shelf.
