Texas Instruments provides a layout and routing guide in the application note SLAA332, which recommends keeping the analog and digital grounds separate, using a solid ground plane, and minimizing the length of the analog input traces.
The ADS8345EB/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.
The maximum sampling rate of the ADS8345EB/2K5 is 100 kSPS, but this can be limited by the system clock frequency, the conversion mode, and the interface mode. The datasheet provides more information on the sampling rate limitations.
Yes, the ADS8345EB/2K5 can be used in a multi-channel application by using multiple devices or by using a multiplexer to switch between multiple input channels. However, the device does not have a built-in multiplexer, so an external multiplexer would be required.
The power consumption of the ADS8345EB/2K5 is typically around 15 mW at 3 V and 100 kSPS. Power consumption can be minimized by reducing the clock frequency, using the power-down mode, and optimizing the system design to minimize the number of conversions required.
