♦ +2.5V to +5.5V Single-Supply Operation  
♦ ±1LSB (max) TUE  
The MAX548A/MAX549A/MAX550A serial, 8-bit voltage-  
output digital-to-analog converters (DACs) operate from  
a single +2.5V to +5.5V supply. Their ±1LSB TUE spec-  
ification is guaranteed over temperature. Operating cur-  
rent (supply current plus reference current) is typically  
♦ Power-On Reset Clears All Registers to Zero  
♦ Low Operating Current:  
75µA per DAC with V  
= 2.5V. In shutdown, the DAC  
DD  
is disconnected from the reference, reducing current  
drain to less than 1µA. The MAX548A/MAX549A allow  
each DAC to be shut down independently.

= +2.5V)

75µA (MAX550A, V  
= +2.5V)

♦ 1µA Shutdown Mode  
The 10MHz, 3-wire serial interface is compatible with  
SPI™/QSPI™ a nd Mic rowire ™ inte rfa c e s ta nd a rd s .  
Double-buffered inputs provide flexibility when updat-  
ing the DACs; the input and DAC registers can be  
updated individually or simultaneously.  
♦ 10MHz, 3-Wire Serial Interface Compatible with  
SPI/QSPI and Microwire  
♦ µMAX Package—50% Smaller than 8-Pin SO  
♦ Independent Shutdown of DACs  
The MAX548A is a dual DAC with an asynchronous  
(MAX548A/MAX549A)  
load input; it uses V  
as the reference input. The  
DD  
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 con-  
sumption and small µMAX and DIP packages make  
these devices ideal for portable and battery-powered  
applications.
