[vdd=3.6v, rl=8 ? , thd+n Q 1%] 8) audio analog input (corresponds to single-end input / differential input) 9) output lc filter free 10) pop noise suppression circuit 11) shutdown function (use as mute at the same time) [low shutdown current = 0.01 a (typ.)] 12) contains protection circuit: output short, t hermal shutdown, under voltage lockout (uvlo) a p p lic ati o n s mobile phone, portable audio devic e, pnd, dsc, note-pc etc. a b s o lute maximu m rating(t a=+ 2 5 ) parameter symbol ratings unit power supply voltage vddmax pvddmax 7.0 v power dissipation pd 690 mw storage temperature range tstg -55 +150 sdnb pin input range v sdnb -0.3 vdd+0.3 v in+, in- pin input range v in -0.3 vdd+0.3 v in case ta=+25 or more, 5.52 mw decrease per 1 when mounting rohm typical board 50.0mm58.0mm (material: glass epoxy) o per ati on ra n ge parameter symbol range unit temperature topr -40 +85 power supply voltage vdd pvdd +2.5 +5.5 v common mode input voltage range v ic +0.5 vdd-0.8 v this product is not designed for protection against radioactive rays. no.10101eat06 downloaded from: http:///
