ADS1230IPWRG4 datasheet by Texas Instruments

ADS1230IPWRG4 Frequently Asked Questions (FAQs)

• What is the recommended layout and placement for the ADS1230IPWRG4?
  Texas Instruments recommends a 4-layer PCB with a solid ground plane, and placing the device close to the analog input pins to minimize noise. Additionally, decoupling capacitors should be placed as close as possible to the device's power pins.
• How do I optimize the performance of the ADS1230IPWRG4 in a noisy environment?
  To optimize performance in a noisy environment, use a low-pass filter on the analog input, use a shielded cable for the analog input, and consider using a separate analog ground plane. Additionally, ensure that the digital and analog grounds are separated and connected only at the ADC.
• What is the maximum sampling rate that can be achieved with the ADS1230IPWRG4?
  The maximum sampling rate of the ADS1230IPWRG4 is 80SPS (samples per second) in continuous conversion mode, and 40SPS in single-shot mode.
• How do I calibrate the ADS1230IPWRG4?
  The ADS1230IPWRG4 has an internal calibration circuit that can be initiated by setting the CAL pin high. The device will then perform a self-calibration routine, which takes approximately 10ms to complete.
• What is the power consumption of the ADS1230IPWRG4?
  The power consumption of the ADS1230IPWRG4 is typically 12mW at 3.3V supply voltage, and 20mW at 5V supply voltage.
