MAX696CWE+T datasheet by Maxim Integrated Products

MAX696CWE+T Frequently Asked Questions (FAQs)

• What is the recommended layout and routing for the MAX696CWE+T to minimize EMI and noise?
  Maxim provides a layout and routing guide in their application note AN4341, which recommends keeping the input and output traces short and away from each other, using a solid ground plane, and placing bypass capacitors close to the device.
• How do I ensure the MAX696CWE+T is properly powered up and initialized?
  The MAX696CWE+T requires a power-on reset (POR) circuit to ensure proper initialization. A 10kΩ pull-up resistor on the EN pin and a 100nF capacitor on the VCC pin are recommended to ensure a clean power-up sequence.
• What is the maximum current that can be sunk or sourced by the MAX696CWE+T's output drivers?
  The MAX696CWE+T's output drivers can sink or source up to 20mA of current, but this should be derated based on the ambient temperature and the number of outputs being driven.
• How do I troubleshoot issues with the MAX696CWE+T's I2C interface?
  Use a logic analyzer or oscilloscope to verify the I2C clock and data signals, and check for proper pull-up resistors on the SCL and SDA lines. Also, ensure that the I2C address is correctly set and that there are no bus conflicts.
• What is the recommended operating temperature range for the MAX696CWE+T?
  The MAX696CWE+T is rated for operation from -40°C to +125°C, but the device's performance and reliability may be affected at extreme temperatures. Ensure proper thermal management and derating for high-temperature applications.
