The recommended layout and routing for the ADS7961SRHBR 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 ADS7961SRHBR 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 analog and digital grounds are properly separated and that the power supply is well-regulated.
The maximum sampling rate of the ADS7961SRHBR is 100 kSPS. However, the actual sampling rate may be limited by the system's clock frequency, the analog input bandwidth, and the digital interface.
The ADS7961SRHBR does not require calibration. However, it's recommended to perform a system-level calibration to ensure that the ADC is operating within the desired specifications. This can be done by applying a known input signal and adjusting the system's gain and offset to achieve the desired accuracy.
The power consumption of the ADS7961SRHBR depends on the operating mode and the clock frequency. In normal operation, the power consumption is typically around 15 mW. In power-down mode, the power consumption is typically around 1 μW.
