ADS1282SKGDA datasheet by Texas Instruments

ADS1282SKGDA Frequently Asked Questions (FAQs)

• What is the recommended layout and placement for the ADS1282SKGDA?
  Texas Instruments provides a recommended layout and placement guide in the ADS1282SKGDA evaluation module user's guide (SLAU445). It's essential to follow this guide to ensure optimal performance and minimize noise coupling.
• How do I optimize the analog front-end (AFE) for my specific application?
  The ADS1282SKGDA has a flexible AFE that can be optimized for different applications. TI provides an AFE optimization tool (AFE-OPT) that helps designers select the optimal AFE configuration for their specific application. The tool can be found on the TI website.
• What is the maximum input voltage range for the ADS1282SKGDA?
  The ADS1282SKGDA has a maximum input voltage range of ±VREF (±2.5V or ±5V, depending on the VREF pin configuration). However, the device can tolerate input voltages up to ±6V without damage, but the accuracy and linearity may be compromised.
• How do I handle the high-speed digital outputs of the ADS1282SKGDA?
  The ADS1282SKGDA has high-speed digital outputs that require careful handling to minimize signal degradation and noise coupling. TI recommends using a low-impedance transmission line, such as a 50Ω microstrip or stripline, and terminating the lines with a 50Ω resistor to match the output impedance.
• What is the recommended power-up sequence for the ADS1282SKGDA?
  The recommended power-up sequence for the ADS1282SKGDA is to power up the analog supply (AVDD) first, followed by the digital supply (DVDD), and then the clock signal. This sequence helps to ensure that the device powers up correctly and minimizes the risk of latch-up or other issues.
