Key Featrues
Low Operating Current (75µA typical): The DAC consumes minimal current during operation, significantly reducing power consumption. This is particularly beneficial for energy-sensitive applications like IoT devices or battery-operated systems, extending battery life.
1µA Shutdown Mode: In shutdown mode, the DAC reduces current drain to less than 1µA, further optimizing power efficiency. This feature is critical for applications requiring long standby periods or low-power operation.
±1LSB (max) Total Unadjusted Error (TUE): This high level of accuracy ensures reliable and precise voltage output, improving the overall performance of systems that require consistent and accurate analog signals, such as industrial controls or instrumentation.
3-Wire Serial Interface (SPI/QSPI/Microwire Compatible): The DAC supports a versatile and widely-used serial interface, enabling easy integration with microcontrollers and digital systems. This simplifies design and reduces development time for applications requiring digital-to-analog conversion.
Applications
Digital Gain and Offset Control for Signal Conditioning: These DACs are well-suited for digital gain and offset control in signal conditioning circuits. Their voltage-output capability and low-power operation make them ideal for adjusting amplifier gains or setting comparator thresholds in industrial automation and audio processing systems.
GaAs Amplifier Bias Control: The MAX548A/MAX549A/MAX550A DACs are perfect for controlling bias voltages in GaAs amplifiers used in RF and microwave applications. Their ±1LSB TUE specification ensures accurate and stable bias settings, while the small µMAX package saves space in compact RF designs.
VCXO Frequency Tuning: These DACs are excellent for voltage-controlled crystal oscillator (VCXO) tuning in communication systems. Their precise voltage output and low-power operation enable fine-tuning of oscillator frequencies, ensuring stable and accurate clock generation in wireless and networking equipment.
