MAX548A - Maxim

MAX548A 8-Bit Voltage-Output DACs

The MAX548A/MAX549A/MAX550A serial, 8-bit voltageoutput digital-to-analog converters (DACs) operate from a single +2.5V to +5.5V supply. Their ±1LSB TUE specification is guaranteed over temperature. Operating current (supply current plus reference current) is typically 75µA per DAC with VDD = 2.5V. In shutdown, the DAC is disconnected from the reference, red.
