The recommended layout and routing for the ADS7959SRGET involves keeping the analog and digital grounds separate, using a solid ground plane, and minimizing the length of the analog input traces. Additionally, it is 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 ADS7959SRGET in noisy environments, it is recommended to use a low-pass filter at the analog input, use a shielded cable for the analog input, and use a common-mode choke to reduce electromagnetic interference (EMI). Additionally, it is recommended to use a low-noise power supply and to decouple the power supply lines.
The maximum sampling rate that can be achieved with the ADS7959SRGET is 250 kSPS. However, the actual sampling rate may be limited by the system's clock frequency, the analog input bandwidth, and the digital interface.
The ADS7959SRGET does not require calibration. It has an internal calibration circuit that calibrates the device during power-up. However, it is recommended to perform a system-level calibration to ensure that the overall system meets the required specifications.
The power consumption of the ADS7959SRGET depends on the operating mode and the clock frequency. In normal operating mode, the power consumption is typically around 35 mW. In power-down mode, the power consumption is typically around 10 μW.
