Key Featrues
14-Bit/16-Bit Multiplying DAC: The AD7849 offers a high-resolution digital-to-analog conversion with 14-bit or 16-bit precision, ensuring accurate signal generation and improved performance in applications requiring fine control and precision, such as industrial process controls and instrumentation.
Guaranteed Monotonicity: The DAC guarantees monotonicity to 14 bits for the A grade and to 16 bits for all other grades, ensuring that the output increases or decreases consistently with the input, which is critical for maintaining signal integrity and reliability in control systems.
Output Control on Power-Up and Power-Down: The AD7849 features built-in output control during power-up and power-down sequences, clamping the output to 0 V to prevent unintended signals or damage, enhancing system safety and stability during power transitions.
Internal or External Reset Control: The device allows for both internal and external control of the reset function via the Reset In (RSTIN) input, enabling flexible integration with external systems, such as battery supervisors, to manage output behavior during power anomalies or system resets.
Low Impedance Clamping and Transmission Gate Control: The DAC includes low impedance clamping and transmission gate control mechanisms that ensure the output remains stable and controlled during power supply fluctuations, improving reliability and performance in dynamic operating conditions.
