ADS803E/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 input traces should be short and direct, and the reference voltage pin should be connected to a quiet analog ground. Additionally, decoupling capacitors should be placed close to the power pins.
  • The ADS803E/1K outputs 12-bit data in a serial format. The data can be read using a microcontroller or an FPGA. The data is output in a MSB-first format, and the clock signal is generated by the converter. The user needs to provide a clock signal to the converter to read the data.
  • The maximum sampling rate of the ADS803E/1K is 1 kSPS (kilosamples per second). However, the actual sampling rate may be limited by the system's clock frequency and the conversion time of the ADC.
  • The ADS803E/1K does not require calibration. It is a ratiometric ADC, which means that the output code is proportional to the input voltage and the reference voltage. The converter is calibrated at the factory, and no external calibration is required.
  • The power consumption of the ADS803E/1K is typically 1.5 mW at a supply voltage of 5 V and a sampling rate of 1 kSPS. The power consumption can be reduced by reducing the sampling rate or the supply voltage.
