The recommended layout and routing for the ADS8867IDRCR 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 ADS8867IDRCR 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 or a differential amplifier to reject common-mode noise.
The maximum sampling rate of the ADS8867IDRCR 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 ADS8867IDRCR has an internal calibration circuit that can be enabled by setting the CAL pin high. The calibration process involves shorting the analog input to the internal reference voltage, and then adjusting the offset and gain registers to achieve optimal performance.
The power consumption of the ADS8867IDRCR depends on the operating mode and the clock frequency. In normal operation, the power consumption is typically around 35 mW at 1 MSPS. In power-down mode, the power consumption is typically around 10 μW.
