5V, Low-Power, Single/Dual, 8-Bit Voltage-Output DACs in µMAX Package _______________General Description 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, reducing current drain to less than 1µA.
The MAX548A/MAX549A allow each DAC to be shut down independently.
The 10MHz, 3-wire serial interface is compatible with SPI™/QSPI™ and Microwire™ interface standards.
Double-buffered inputs provide flexibility when updating the DACs; the input and DAC registers can be updated individually or simultaneously.
The MAX548A is a dual DAC with an asynchronous load input; it uses VDD as the reference input.
The MAX549A is a dual DAC with an external reference input.
The MAX550A is a single DAC with an external reference input and an asynchronous load input.
The MAX548A/MAX549A/MAX550A’s low power consumption and small µMAX and DIP packages make these devices ideal for portable and battery-powered applications.
