Texas Instruments provides a layout and routing guide in the application note SLAA554, which recommends keeping the analog and digital grounds separate, using a solid ground plane, and minimizing the length of the analog input traces.
The ADS7816E/250G4 has an internal calibration circuit that can be used to calibrate the device. The calibration process involves writing a specific code to the calibration register, and then reading the calibration data from the device. The calibration data can then be used to correct for any offset and gain errors.
The maximum sampling rate of the ADS7816E/250G4 is 250 kSPS, but this can be affected by the clock frequency, the conversion mode, and the interface mode. The datasheet provides a detailed table showing the maximum sampling rates for different clock frequencies and conversion modes.
The ADS7816E/250G4 outputs 16-bit digital data in a binary two's complement format. The data can be read through the SPI interface, and the datasheet provides a detailed description of the data format and the SPI protocol.
The power consumption of the ADS7816E/250G4 depends on the operating mode, the clock frequency, and the supply voltage. The datasheet provides a detailed table showing the power consumption in different operating modes. To reduce power consumption, the device can be operated in a low-power mode, and the clock frequency can be reduced.
