The recommended layout and routing for the ADS7951SBRGER involves keeping the analog and digital grounds separate, using a solid ground plane, and minimizing the length of the analog input traces. It's also recommended to use a 4-layer PCB with a dedicated analog power plane and a dedicated digital power plane.
To optimize the performance of the ADS7951SBRGER in noisy environments, use a low-pass filter at the input, use a shielded cable for the analog input, and consider using a common-mode filter. Additionally, ensure that the analog and digital grounds are properly separated and that the power supply is well-regulated.
The maximum sampling rate of the ADS7951SBRGER is 1.5 MSPS (mega-samples per second). However, the actual sampling rate may be limited by the system's clock frequency and the conversion time of the ADC.
The ADS7951SBRGER does not require calibration. It has an internal calibration circuit that performs a self-calibration sequence during power-up. However, if you need to perform a system-level calibration, you can use the ADC's built-in calibration registers to adjust the offset and gain of the ADC.
The power consumption of the ADS7951SBRGER depends on the operating mode and the sampling rate. In normal operation, the typical power consumption is around 35 mW at 1.5 MSPS. In power-down mode, the power consumption is around 10 μW.
