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.
