general description
the sn4088 is a dual bridge-connected audio power
amplifier which, when connected to a 5v supply, will
deliver 2.7w to a 4ω load.
the sn4088 features a low-power consumption
shutdown mode and thermal shutdown protection. it also
utilizes circuitry to reduce “clicks and pops” during
device turn-on.
applications
z cell phones, pda, mp4,pmp
z portable and desktop computers
z desktops audio system
z multimedia monitors
