Download the MAX5438 datasheet PDF. This datasheet also includes the MAX5436 variant, as both parts are published together in a single manufacturer document.

General Description

The MAX5436–MAX5439 are 128-tap high-voltage (±5V to ±15V) digital potentiometers in packages that are half the size of comparable 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).

Key Features

  • include low 35ppm/°C end-to-end and 5ppm/°C ratiometric resistor temperature coefficients, a 3-wire SPI™/ QSPI™/.
