ADS7808U/1K Frequently Asked Questions (FAQ)

  • Texas Instruments recommends a 4-layer PCB with a solid ground plane, and placing the ADC close to the analog signal sources. Decoupling capacitors should be placed as close as possible to the power pins, and the analog and digital grounds should be separated and connected at a single point.

  • To minimize EMI, use a low-inductance path for the digital outputs, keep the output traces short and away from sensitive analog signals, and use a series termination resistor (e.g., 22-33 ohms) at the output of the ADC. Additionally, consider using a shielded cable or a twisted pair for the digital output signals.

  • The maximum sampling rate of the ADS7808U/1K is 100 kSPS. However, the actual achievable sampling rate may be limited by the system's clock frequency, the analog input bandwidth, and the digital output data rate. Additionally, the sampling rate may be affected by the conversion mode, gain, and offset settings.

  • The ADS7808U/1K has an internal calibration circuit that can be used to calibrate the ADC. The calibration process involves applying a known input voltage and adjusting the internal offset and gain registers to achieve optimal accuracy and linearity. Refer to the datasheet and application notes for detailed calibration procedures.

  • The power consumption of the ADS7808U/1K depends on the operating mode, sampling rate, and supply voltage. The typical power consumption is around 15 mW at 100 kSPS. To reduce power consumption, consider using the power-down mode, reducing the sampling rate, or operating the ADC at a lower supply voltage.
