TDA7498MV是100W單聲道D類音頻放大器,主要用在家庭影院和有源揚(yáng)聲器. TDA7498MV單電源14-39V工作,效率高達(dá)90%,增益設(shè)定為25.6 dB, 31.6 dB, 35.1 dB和37.6 dB。采用PowerSSO-36封裝。
TDA7498MV主要特性能：
100-W output power at THD = 10% with RL= 6 Ω and VCC = 36 V
80-W output power at THD = 10% with RL= 8 Ω and VCC = 34 V
Wide-range single-supply operation (14 - 39 V)
High efficiency (η = 90%)
Four selectable, fixed gain settings of nominally 25.6 dB, 31.6 dB, 35.1 dB and 37.6 dB
Differential inputs minimize common-mode noise
Standby and mute features
Short-circuit protection
Thermal overload protection
Externally synchronizable
