The recommended layout and routing for the ADS7948SRTET 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 ADS7948SRTET in noisy environments, use a low-pass filter at the analog input, use a shielded cable for the analog input, and consider using a common-mode filter. Additionally, ensure that the digital and analog grounds are separated and that the power supply is well-regulated.
The maximum sampling rate of the ADS7948SRTET is 1 MSPS (million samples per second). However, the actual sampling rate may be limited by the system's clock frequency, the analog input bandwidth, and the digital interface.
The ADS7948SRTET does not require calibration. It has an internal calibration circuit that performs a self-calibration sequence during power-up. However, it's recommended to perform a system-level calibration to ensure accurate measurements.
The power consumption of the ADS7948SRTET depends on the operating mode and the clock frequency. In normal operation, the typical power consumption is around 35 mW at 1 MSPS. In power-down mode, the typical power consumption is around 10 μW.
