🔧 Application Guidelines
Design Considerations
When designing with the AD5320, it is essential to consider the power supply, input signal, and output load to ensure proper operation. The AD5320 operates from a single supply of 2.5 V to 5.5 V, and the input signal should be limited to the range of 0 V to VDD. The output load should be limited to 10 kΩ to ensure proper operation.
Installation Guidelines
The AD5320 is available in a 6-lead SOT-23 package and a 6-lead MSOP package. When installing the AD5320, it is essential to follow proper soldering techniques to ensure reliable operation. The AD5320 should be mounted on a printed circuit board (PCB) with a ground plane to minimize noise and ensure proper operation.
Operational Notes
The AD5320 has a power-down mode that reduces the current consumption to 200 nA at 3 V. This mode is useful for portable battery-powered instruments where power consumption is critical. The AD5320 also features a high speed, low power, digital-to-analog converter that operates from a single supply of 2.5 V to 5.5 V.
