LA4708N - 20W 2-channel BTL AF Power Amplifier

2.2F is recommended.

fL can be varied by C1, C4 capacitances to adjust the bass range.

Approximately 0.8 second for 33F.

• on-chip protectors and standby switch. Features.
• High power : supports total output of 30W  30W (VCC = 13.2V, THD = 30%, RL = 4).
• Supports RL = 2 (PO = 30W when VCC = 13.2V, THD = 10%).
• Designed for excellent sound quality (fL  10Hz, fH = 130kHz).
• NF capacitor-less.
• Any on time settable by external capacitor.
• Less pop noise.
• Standby switch circuit on chip (microprocessor supported).
• Various protectors on chip (output-to-ground short/output-to-VCC shor.
