ADS8344NBG4 Frequently Asked Questions (FAQs)

  • Texas Instruments provides a recommended layout and routing guide in the ADS8344NBG4 evaluation module user's guide (SLAU144). It's essential to follow this guide to ensure proper operation and minimize noise and interference.
  • The ADS8344NBG4 outputs 16-bit data in a serial format. You'll need to use a microcontroller or FPGA to receive and process the data. You can use a SPI or QSPI interface to communicate with the device. Make sure to follow the timing diagrams and protocol specified in the datasheet.
  • The POR timing is not explicitly stated in the datasheet. According to Texas Instruments, the POR timing is typically around 10 ms, but it can vary depending on the specific application and power supply conditions. It's recommended to add an external POR circuit or use a microcontroller to handle the power-on reset sequence.
  • Yes, the ADS8344NBG4 can be used in a multiplexed configuration. However, you'll need to add external multiplexers and control logic to select the desired input channels. Make sure to consider the additional noise and settling time introduced by the multiplexers when designing your system.
  • The ADS8344NBG4 requires a two-point calibration procedure to ensure accurate conversions. You'll need to apply a known input voltage to the device and measure the output code. Then, use the measured code to calculate the gain and offset coefficients. Refer to the datasheet and application notes for more details on the calibration procedure.
