AD7891AP-2 Frequently Asked Questions (FAQ)
-
A good layout and grounding technique is crucial for the AD7891AP-2. It is recommended to use a multi-layer PCB with a solid ground plane, and to keep the analog and digital grounds separate. The analog ground should be connected to the digital ground at a single point, usually near the AD7891AP-2. Additionally, it is recommended to use a star-grounding configuration and to avoid running digital lines under the AD7891AP-2.
-
The AD7891AP-2 outputs 12-bit data in a serial format. The output data is in two's complement format, and it is recommended to use a microcontroller or a digital signal processor to handle the output data. The user should also ensure that the microcontroller or digital signal processor is configured to handle the serial data output from the AD7891AP-2.
-
The maximum sampling rate of the AD7891AP-2 is 57 kHz. However, the actual sampling rate may be limited by the conversion time, the clock frequency, and the microcontroller or digital signal processor used to handle the output data.
-
The AD7891AP-2 does not require any external calibration. The device has an internal calibration circuit that calibrates the ADC during power-up. However, the user may need to perform a system-level calibration to ensure that the overall system meets the required accuracy and linearity specifications.
-
The power consumption of the AD7891AP-2 depends on the operating mode and the clock frequency. In normal mode, the typical power consumption is around 15 mW, and in shutdown mode, the typical power consumption is around 10 μW.
