ADS8345N/1K Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a 4-layer PCB with a solid ground plane, and to keep the analog and digital signals separate. The analog input traces should be short and direct, and the digital output traces should be routed away from the analog inputs. Additionally, decoupling capacitors should be placed close to the device's power pins.
  • The POR and BOR circuits in the ADS8345N/1K ensure that the device resets properly during power-up and power-down sequences. To handle these resets, the system designer should ensure that the power supply ramps up and down slowly, and that the device's reset pin is properly connected to a reset circuit or a microcontroller's reset input.
  • The ADS8345N/1K can operate with a clock frequency between 1 MHz and 4 MHz. A clock frequency of 2 MHz is recommended for optimal performance. The clock source can be an external clock signal or the device's internal oscillator. If using an external clock, it should be a stable, low-jitter clock signal.
  • The ADS8345N/1K does not require calibration, as it is a self-calibrating device. However, the system designer should ensure that the device is operated within its specified temperature range and that the analog input signals are within the device's specified input range.
  • The ADS8345N/1K's digital output can be interfaced with a microcontroller or digital signal processor using a standard SPI or QSPI interface. The system designer should ensure that the interface is properly configured and that the device's output data is properly synchronized with the microcontroller's or DSP's clock signal.
