Overview

+2.5V to +5.5V Single-Supply Operation
±1LSB (max) TUE
Power-On Reset Clears All Registers to Zero
Low Operating Current:
- 150µA (MAX548A/MAX549A, V_REF = +2.5V)
- 75µA (MAX550A, V_REF = +2.5V)
1µA Shutdown Mode
10MHz, 3-Wire Serial Interface Compatible with SPI/QSPI and Microwire
µMAX Package-50% Smaller than 8-Pin SO
Independent Shutdown of DACs (MAX548A/MAX549A)

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 specification is guaranteed over temperature. Operating current (supply current plus reference current) is typically 75µA per DAC with V_DD = 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 V_DD 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.
