Description

General part information

MAX548 Series

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 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 VDDas 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.ApplicationsBattery-Powered ApplicationsComparator-Level SettingsDigital Gain and Offset ControlGaAs Amp Bias ControlGeneral PurposeVCXO Control
