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/2K5G4 has an internal calibration circuit that can be used to calibrate the device. The calibration process involves applying a known input voltage and reading the output code. The device can then be calibrated using the internal calibration circuit or through external calibration using a microcontroller.
The maximum sampling rate of the ADS7816E/2K5G4 is 250 kSPS. However, the actual sampling rate may be limited by the system clock frequency, the conversion time, and the settling time of the analog input signal.
The ADS7816E/2K5G4 outputs 16-bit digital data in a binary two's complement format. The data can be read using a microcontroller or a digital signal processor, and can be processed using software or hardware algorithms to extract the desired information.
The power consumption of the ADS7816E/2K5G4 is typically around 15 mW at a supply voltage of 2.7 V. The power consumption can be reduced by using a lower supply voltage, reducing the sampling rate, or using the device's power-down mode.
