MAX5436 Overview
The MAX5436 MAX5439 are 128-tap high-voltage (±5V to ±15V) digital potentiometers in packages that are half the size of parable devices in 8-pin SO. They perform the same function as mechanical potentiometers, but replace the mechanics with a simple digital interface. The digital logic is powered by a separate single +2.7V to +5.25V supply voltage (VCC).
