AD7998BRU-0 Frequently Asked Questions (FAQ)
-
A good layout and routing practice is to keep the analog and digital grounds separate, use a solid ground plane, and keep the analog signals away from the digital signals. Also, use a low-ESR capacitor for the AVDD and DVDD pins, and keep the traces short and direct.
-
The AD7998BRU-0 has an internal calibration circuit that is performed during power-up. However, it's recommended to perform an external calibration by writing to the CAL register to ensure accurate conversions. Refer to the datasheet for the calibration procedure.
-
The AD7998BRU-0 can achieve a maximum sampling rate of 250 kSPS (kilo-samples per second) in the fast mode, and 125 kSPS in the normal mode. However, the actual sampling rate may vary depending on the system clock frequency and the conversion mode.
-
In such cases, try resetting the AD7998BRU-0 by asserting the RESET pin low for at least 10 ns. If the issue persists, check the power supply, clock, and interface signals for any errors or noise. Also, ensure that the device is properly configured and the registers are written correctly.
-
Yes, the AD7998BRU-0 can be used in a multi-channel configuration by using the SCAN mode. In this mode, the device can scan and convert multiple channels sequentially. The channel selection is done using the CH[2:0] pins, and the conversion result is stored in the ADC result register.
