The recommended layout and routing for the ADS8681IRUMR 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 ADS8681IRUMR 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 ADS8681IRUMR is 1 MSPS (million samples per second) for all channels. However, the actual sampling rate may be limited by the system's clock frequency, the number of channels being sampled, and the system's overall throughput.
The ADS8681IRUMR does not require calibration in the classical sense. However, it's recommended to perform a system-level calibration to ensure that the ADC is operating within its specified accuracy. This can be done by applying a known input voltage and measuring the output code to determine the gain and offset errors.
The power consumption of the ADS8681IRUMR depends on the operating mode and the sampling rate. In normal operation, the device consumes around 35 mW at 1 MSPS. In power-down mode, the device consumes around 10 μW.
