Texas Instruments recommends a 4-layer PCB with a solid ground plane, and to keep the analog and digital signals separate. The analog signals should be routed close to the ADC, and the digital signals should be routed away from the ADC. Additionally, the power and ground pins should be decoupled with 0.1uF and 10uF capacitors.
To optimize the performance of the ADS8694IDBT in noisy environments, use a low-pass filter at the input, use a shielded cable, and keep the ADC away from noise sources. Additionally, use a common-mode filter or a differential filter to reduce common-mode noise.
The maximum sampling rate of the ADS8694IDBT is 250kSPS. However, the actual sampling rate may be limited by the system's clock frequency, the input signal's bandwidth, and the system's noise floor.
The ADS8694IDBT has an internal calibration circuit that can be enabled by setting the CAL bit in the control register. The calibration process takes approximately 100us and should be performed after power-up or after a reset. The calibration process adjusts the ADC's offset and gain to ensure accurate conversions.
The power consumption of the ADS8694IDBT depends on the operating mode and the sampling rate. In normal mode, the power consumption is approximately 35mW at 250kSPS. In low-power mode, the power consumption is approximately 10mW at 100kSPS.
