LM4673SD Frequently Asked Questions (FAQs)

  • The minimum recommended supply voltage is 4.5V, although the device can operate down to 3.5V with reduced performance.
  • To ensure stability, use a minimum 10uF ceramic capacitor between the VIN and PG pins, and a 0.1uF ceramic capacitor between the BYPASS pin and GND. Additionally, keep the PCB layout compact and minimize trace lengths.
  • The maximum output power of the LM4673SD is approximately 2.3W per channel when using a single 5V supply voltage, and 1.1W per channel when using a single 3.3V supply voltage.
  • To configure the LM4673SD for a BTL configuration, connect the output of one amplifier to the input of the other amplifier, and tie the two outputs together. This will allow the device to drive a single load with increased power.
  • The recommended heat sink for the LM4673SD is a thermal pad or a heat sink with a thermal resistance of less than 10°C/W. A heat sink is required to maintain a safe junction temperature, especially at high output powers.
