LM1875T/LF05 Frequently Asked Questions (FAQs)

  • TI recommends using a 10uF ceramic capacitor in parallel with a 100nF ceramic capacitor, both connected between the power supply pins (VCC and GND) and placed as close to the IC as possible.
  • To ensure stability, TI recommends using a minimum of 100pF capacitor between the output pin (OUT) and the inverting input pin (IN-), and a minimum of 10kΩ resistor between the output pin (OUT) and the non-inverting input pin (IN+).
  • The maximum output current of the LM1875T is 250mA. However, it's recommended to limit the output current to 100mA for optimal performance and to prevent overheating.
  • Yes, the LM1875T can be used as a headphone amplifier. However, it's essential to ensure that the output power is limited to prevent damage to the headphones or hearing loss. A maximum output power of 100mW per channel is recommended.
  • To reduce noise and hum, TI recommends using a well-regulated power supply, keeping the input and output traces as short as possible, and using a shielded cable for the input signal. Additionally, using a 10uF capacitor between the power supply pins (VCC and GND) can help reduce noise.
