ETK4888, Dual bridge-connected audio power amplifier

The ETK4888 is a dual bridgeconnected audio power amplifier which, when connected to a 5V supply, will deliver 2.1W to a 4Ω load or 2.4W to a 3Ω load with less than 1.0% THD+N.

The ETK4888 also has two separate HP (headphone) enable inputs, each having different logic level thresholds. Either HP en
