APA0712 - ANPEC

APA0712 1.4W Mono Audio Low-Voltage Audio Power Amplifier

The APA0712 is a mono BTL audio power amplifier developed especially for low-voltage applications where internal speakers are required. Operating with a 5V supply, the APA0712 can deliver 1.4W of continuous power into a BTL 8Ω load at 10% THD+N throughout voice band frequencies. Although this device is characterized out to 20kHz, its operation is optimized f.
