ADS58B19IRGZT datasheet by Texas Instruments

ADS58B19IRGZT Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance?
  Texas Instruments provides a recommended PCB layout in the ADS58B19IRGZT evaluation module documentation. It's essential to follow the layout guidelines to minimize noise, ensure proper grounding, and optimize signal integrity.
• How do I configure the device for different gain settings?
  The ADS58B19IRGZT has a programmable gain amplifier (PGA) that can be configured using the SPI interface. Refer to the device's programming guide and the PGA configuration register descriptions in the datasheet to set the desired gain.
• What is the maximum input voltage range for the analog inputs?
  The ADS58B19IRGZT can handle input voltages up to VREF (reference voltage) + 0.3V. However, it's recommended to keep the input voltage within the specified range of VREF ± 10% to ensure accurate conversions.
• How do I handle clock jitter and ensure accurate sampling?
  To minimize clock jitter, use a high-quality clock source, such as a crystal oscillator, and ensure proper decoupling and filtering. Additionally, use the device's internal clock jitter filter or implement an external filter to reduce jitter.
• What is the recommended power-up sequence for the device?
  The recommended power-up sequence is to power up the analog supply (AVDD) first, followed by the digital supply (DVDD), and then the clock signal. This sequence helps prevent latch-up and ensures proper device operation.
