SGM4888 Description
The SGM4888 is a dual bridge-connected audio power amplifier which, when connected to a 5V supply, will deliver 2.1W into a 4Ω load or 2.5W into a 3Ω load with typically 1% THD+N. The SGM4888 has two separate HP (headphone) enable inputs, each having different logic level thresholds. Either HP enable input activates the single-ended headphone mode and disables the BTL output mode.
