ISO721MDG4 datasheet by Texas Instruments

ISO721MDG4 Frequently Asked Questions (FAQs)

• What is the maximum data rate that can be achieved with the ISO721MDG4?
  The maximum data rate of the ISO721MDG4 is 150 Mbps, but it can be limited by the specific application, PCB layout, and signal integrity.
• How do I ensure signal integrity and minimize EMI with the ISO721MDG4?
  To ensure signal integrity and minimize EMI, follow proper PCB layout guidelines, use differential signaling, and add shielding or guard rings around the isolation barrier. Additionally, use a common-mode choke and decoupling capacitors to filter out noise.
• What is the recommended power supply configuration for the ISO721MDG4?
  The recommended power supply configuration for the ISO721MDG4 is a split-supply configuration, where VCC1 and VCC2 are connected to separate power supplies, and GND1 and GND2 are connected to separate grounds. This ensures proper isolation between the input and output sides.
• How do I handle the input common-mode voltage range for the ISO721MDG4?
  The input common-mode voltage range for the ISO721MDG4 is -10 V to +10 V. To handle this range, ensure that the input signal is within the specified range, and consider using a voltage divider or level-shifting circuit if necessary.
• What is the typical propagation delay for the ISO721MDG4?
  The typical propagation delay for the ISO721MDG4 is around 10 ns, but it can vary depending on the specific application, temperature, and operating conditions.
