General Description

The MAX550B serial, 8-bit, voltage-output, digital-toanalog converter (DAC) operates on a single +2.5V to +5.5V supply. Its ±1LSB TUE specification is guaranteed over temperature. Operating current (supply current plus reference current) is typically 75µA with VDD = 2.5V and less than 1µA in shutdown mode. The reference input is disconnected from the REF pin during shutdown.
