The recommended layout and routing for the ADS7263SRHBR 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 ADS7263SRHBR 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. Additionally, ensure that the analog and digital grounds are properly separated and decoupled.
The maximum sampling rate of the ADS7263SRHBR is 500 kSPS (kilosamples per second). However, the actual sampling rate may be limited by the system clock frequency, the analog input bandwidth, and the digital interface used.
The ADS7263SRHBR has an internal calibration circuit that can be used to calibrate the device. The calibration process involves applying a known input voltage to the device and then using the calibration registers to adjust the gain and offset of the ADC. The calibration process should be performed at power-up and after any changes to the system configuration.
The power consumption of the ADS7263SRHBR depends on the operating mode and the sampling rate. In normal operation, the device consumes around 15 mW at 500 kSPS. In power-down mode, the device consumes around 10 μW.
