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 R_L= 6 Ω and V_CC = 36 V

80-W output power at THD = 10% with R_L= 8 Ω and V_CC = 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
