SA4871 3W Mono Low-Voltage Audio Power Amplifier Features General Description • Operating Voltage : 2.5V-5.5V • Bridge-Tied Load (BTL) Mode Operation • • • Supply Current – IDD=7mA at VDD=5V Low Shutdown Current – IDD=0.1µA Low Distortion –2.5W, at VDD=5V, BTL, RL=3Ω The SA4871 is a bridged-tied load (BTL) audio power amplifier developed especially for low-voltage applications where internal speakers. Operating with a 5V supply, the SA4871 can deliver 3.3W of continuous power into a BTL 3Ω load at 10% THD+N THD+N=0.1% throughout voice band frequencies. Although this –2.1W, at VDD=5V, BTL, RL=4Ω device is characterized out to 20kHz, its operation is THD+N=0.1% optimized for narrow band applications such as • Output Power wireless communications.
