The LM4895LD is a fully differential audio power amplifier designed for mobile and portable communication applications. It delivers 1 watt of continuous average power to an 8,Ѷ load with less than 1% total harmonic distortion plus noise (THD+N) from a 5V DC power supply. The amplifier operates within a voltage range of 2.2V to 5.5V and features an internally fixed gain of 6dB. This device includes advanced pop and click circuitry to eliminate noise during turn-on and turn-off transitions, making it suitable for applications where audio quality is critical. It can drive capacitive loads up to 500 pF and does not require output coupling or bootstrap capacitors, which simplifies the design and reduces component count. The LM4895LD also features a low-power shutdown mode with a typical shutdown current of 0.1¬µA, enhancing its efficiency in battery-operated devices. Thermal shutdown protection is included to prevent overheating, and the device is available in space-saving packages such as micro SMD, VSSOP, and WSON. This amplifier is ideal for use in mobile phones, PDAs, and other portable electronic devices where size and power efficiency are important considerations.
