Key Featrues
±1LSB Total Unadjusted Error (TUE): The DAC guarantees a maximum TUE of ±1LSB over temperature, ensuring high accuracy and reliability in analog output. This precision is critical for applications requiring consistent and dependable voltage outputs, such as comparator-level settings or digital gain control.
Low Operating Current (75µA typical): With a typical operating current of 75µA at 2.5V, the DAC minimizes power consumption, making it suitable for energy-sensitive applications like portable devices or IoT systems. This contributes to longer battery life and improved energy efficiency.
1µA Shutdown Mode: The DAC can enter a shutdown mode where current consumption drops to just 1µA, significantly reducing power usage when the device is idle. This feature is particularly beneficial for power-sensitive designs, extending operational life in battery-powered scenarios.
SPI/QSPI/Microwire-Compatible 3-Wire Serial Interface: The 10MHz serial interface ensures fast and efficient communication with microcontrollers or other digital systems. Its compatibility with SPI, QSPI, and Microwire protocols simplifies integration into a wide range of digital designs, enhancing flexibility and ease of use.
Applications
Precision Comparator-Level Adjustment: These DACs are perfect for setting precise comparator thresholds in control systems. With ±1LSB TUE (Total Unadjusted Error) and voltage-output capability, they ensure accurate level settings for comparators in applications like overvoltage protection, signal conditioning, or threshold detection in industrial and automotive systems.
Digital Gain and Offset Calibration: The MAX548A/MAX549A/MAX550A can be used for digital gain and offset control in signal processing chains. Their 8-bit resolution and voltage-output architecture allow fine-tuning of analog signals in audio equipment, instrumentation, or communication systems, ensuring optimal signal integrity and performance.
VCXO Frequency Control: These DACs are ideal for controlling Voltage-Controlled Crystal Oscillators (VCXOs) in communication and timing systems. Their low-power operation and precise voltage output enable stable and accurate frequency tuning, making them suitable for applications like clock synchronization, frequency modulation, or phase-locked loops (PLLs).
