ADS1211U Frequently Asked Questions (FAQ)

  • The ADS1211U requires careful layout and placement to minimize noise and ensure accurate conversions. TI recommends placing the device close to the analog signal source, using a solid ground plane, and keeping analog and digital traces separate. Additionally, decoupling capacitors should be placed close to the device's power pins.

  • To optimize the ADS1211U's performance for low-noise applications, use a low-noise voltage reference, minimize digital noise coupling, and use a high-quality analog input filter. Additionally, consider using a shielded enclosure and keeping the device away from high-frequency sources.

  • The ADS1211U can achieve a maximum sampling rate of 4 kSPS (kilosamples per second) in continuous conversion mode. However, this rate may vary depending on the specific application and system requirements.

  • The ADS1211U outputs 24-bit data in twos-complement format. To handle the output data, use a microcontroller or FPGA to read the data and perform any necessary processing, such as scaling, offset correction, and filtering.

  • The ADS1211U's power consumption is typically around 12 mW at 3.3 V and 4 kSPS. To minimize power consumption, consider using a lower supply voltage, reducing the sampling rate, and using the device's power-down mode when not in use.
