Texas Instruments provides a layout and routing guide in the application note SLAA382, which recommends keeping the analog and digital grounds separate, using a solid ground plane, and minimizing the length of the analog input traces.
The ADS8324E/2K5 has an internal calibration circuit that can be used to calibrate the device. The calibration process involves applying a known input voltage and then reading the output code. The device can then be calibrated by adjusting the internal offset and gain registers. Texas Instruments provides a calibration procedure in the application note SLAA383.
The maximum sampling rate of the ADS8324E/2K5 is 100 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.
Yes, the ADS8324E/2K5 can be used in a multiplexed configuration. The device has a separate analog input pin for each channel, and the channels can be multiplexed using an external multiplexer. However, the multiplexing scheme should be designed to minimize the settling time and ensure that the analog input signal is stable before the conversion starts.
The ADS8324E/2K5 outputs 16-bit digital data in a binary two's complement format. The data can be read using a serial interface, such as SPI or I2C. The host controller should be configured to read the data in the correct format and handle the data accordingly. Texas Instruments provides example code and interface diagrams in the datasheet and application notes.
