MAX5417/MAX5418/MAX5419 are non-volatile, linear digital potentiometers with 256 tap points. They can be controlled through a simple 2-wire digital interface and allow for communication with multiple devices.
The MAX5417, MAX5418, and MAX5419 are 256‑tap, non‑volatile digital potentiometers that communicate via an I²C/SMBus interface. They are offered in a 3 mm × 3 mm TDFN‑EP package and operate from 2.7 V to 5.25 V.
These devices provide low‑power standby operation (≈500 nA), selectable tap resistance values (50 kΩ, 100 kΩ, 200 kΩ), and precise linearity (±0.5 LSB INL/DNL). Typical applications include LCD contrast control, programmable filters, and adjustable voltage references.
