Key Features
- Low Power Consumption: The AD5664ARMZ operates with a power consumption of 2.25 mW at 5 V and reduces to 2.4 μW in power-down mode, making it suitable for battery-operated devices.
- High Precision: The device features a relative accuracy of ±12 LSBs maximum and is guaranteed monotonic by design.
- Versatile Interface: Compatible with standard SPI®, QSPI™, MICROWIRE™, and DSP interface standards, allowing for data transfer rates up to 50 MHz.
- Rail-to-Rail Output: The on-chip precision output amplifier enables rail-to-rail output swing.
- Power-On Reset and Power-Down Feature: Ensures the DAC output powers up to 0 V and remains there until a valid write takes place, and reduces current consumption in power-down mode.
Applications
The AD5664ARMZ is suitable for a variety of applications, including:
- Portable battery-operated equipment due to its low power consumption.
- Industrial control systems requiring high precision and reliability.
