AD7718BR Frequently Asked Questions (FAQ)
-
The AD7718BR is a sensitive analog device, and proper layout and placement are crucial for optimal performance. It is recommended to keep the analog and digital grounds separate, use a solid ground plane, and keep the analog input traces short and away from digital signals. Additionally, the device should be placed close to the analog input sources to minimize noise pickup.
-
The AD7718BR has an internal calibration mechanism that can be initiated by writing to the CAL register. The device can be calibrated in the factory or in the system. The calibration process involves writing a specific code to the CAL register, which triggers the internal calibration sequence. The device then adjusts its internal gain and offset to ensure accurate conversions.
-
The AD7718BR's performance is affected by temperature, particularly in terms of offset and gain drift. The device's offset voltage can drift by up to ±10 μV/°C, and the gain can drift by up to ±10 ppm/°C. However, the device's internal calibration mechanism can compensate for these drifts to some extent. It is recommended to use external temperature compensation or calibration techniques to ensure optimal performance over the desired temperature range.
-
The AD7718BR is a sensitive analog device and can be affected by electromagnetic interference (EMI) and radio-frequency interference (RFI). To minimize the effects of EMI and RFI, it is recommended to use proper shielding, grounding, and filtering techniques. The device's analog input traces should be kept short and shielded, and the device should be placed in a shielded enclosure. Additionally, the use of EMI filters and RFI absorbers can help reduce the impact of external interference.
-
The recommended power-up sequence for the AD7718BR is to power up the analog supply (AVDD) first, followed by the digital supply (DVDD). This ensures that the analog circuitry is powered up before the digital circuitry, which helps to prevent any potential latch-up or damage to the device.
