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. The HP Sense
input is for use with a normal stereo headphone jack. The
remaining input, HP Logic, accepts standard logic level
thresholds.
To simplify audio system design, the SGM4888 combines
dual bridge speaker amplifiers and stereo headphone
amplifiers on one chip. SGM4888YTQF24G/TR资料下载
