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.

Features
♦ +2.5V to +5.5V Single-Supply Operation
♦ ±1LSB (max) TUE
♦ Low 75µA Operating Current (VDD = +2.5V)
♦ 1µA Shutdown Mode
♦ µMAX Package—50% Smaller than 8-Pin SO
♦ 10MHz, 3-Wire Serial Interface
♦ Internal Power-On Reset Clears All Registers to Zero

Applications
    VCXO Control
