Texas Instruments provides a recommended layout and routing guide in their application note SLAA382, which includes guidelines for PCB layout, component placement, and routing to minimize noise and ensure optimal performance.
The ADS8343EBG4 does not require calibration in the classical sense, but it does require a zero-scale calibration to remove any offset errors. This can be done by shorting the analog input to ground and adjusting the digital output to zero. Additionally, gain calibration can be performed by applying a known input voltage and adjusting the digital output to the expected value.
The maximum sampling rate of the ADS8343EBG4 is 100 kSPS, but this can be affected by the clock frequency, conversion mode, and other system-level factors. It's recommended to consult the datasheet and application notes for specific guidance on achieving the highest possible sampling rate.
Yes, the ADS8343EBG4 can be used in a multiplexed configuration, but it requires additional external circuitry to multiplex the analog inputs. Texas Instruments provides an application note (SLAA387) that provides guidance on designing a multiplexed ADC system using the ADS8343EBG4.
The ADS8343EBG4 has an internal overvoltage protection circuit that protects the device from input voltages up to 15V. However, it's still recommended to add external overvoltage protection circuitry to prevent damage from high-voltage transients or faults. A simple resistor-divider network or a dedicated overvoltage protection IC can be used for this purpose.
