Single_chip_audio_amplifier_BTL_stereo_1_W
This circuit is similar to that of Fig. 1-27, except that no built-in volume control is provided, and two (stereo) channels are available. The supply range is from 3 V to 18 V. The circuit provides a 1-W per channel output, with a 6-V supply, into 8-Ω stereo loads, or 2-W per channel output, with an 11-V supply, into 25-Ω loads. Fixed, closed-loop voltage gain is 39 dB (6-V supply, 8-Ω load).
