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 ADS8344E/2K5G4 has an internal calibration circuit that can be used to calibrate the device. The calibration process involves writing specific values to the calibration registers, and then performing a self-calibration sequence. The details of the calibration process are provided in the datasheet and the application note SLAA383.
The maximum sampling rate of the ADS8344E/2K5G4 is 100 kSPS per channel, but it can be affected by the clock frequency and the number of channels being converted. The device can operate with a clock frequency up to 20 MHz, and the sampling rate can be calculated using the formula provided in the datasheet.
The ADS8344E/2K5G4 can be interfaced with a microcontroller or FPGA using a serial interface, such as SPI or I2C. The recommended communication protocols are provided in the datasheet, and Texas Instruments also provides example code and interface diagrams in the application notes SLAA384 and SLAA385.
The ADS8344E/2K5G4 has a typical power consumption of 15 mW at 100 kSPS, and it has several power-down modes that can be used to minimize power consumption. The device can be powered down by setting the PDWN pin low, and the power consumption can be further reduced by using the auto-power-down mode, which automatically powers down the device when not in use.
