MAX550A - 8-Bit Voltage-Output DACs

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.

Key Features

  • o +2.5V to +5.5V Single-Supply Operation o ±1LSB (max) TUE o Power-On Reset Clears All Registers to Zero o Low Operating Current: 150µA (MAX548A/MAX549A, VREF = +2.5V) 75µA (MAX550A, VREF = +2.5V) o 1µA Shutdown Mode o 10MHz, 3-Wire Serial Interface Compatible with SPI/QSPI and Microwire o µMAX Package.

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.
