TDA7492MV是50W单声道BTL D类音频放大器,主要用在家庭影院和有源扬声器. TDA7492MV单电源10-26V工作,效率高达90%,增益设定为21.6 dB, 37.6 dB, 31.1 dB和33.6 dB。采用PowerSSO-36封装。

TDA7492MV主要特性:

• 50 W continuous output power:RL = 6 Ω, THD = 10% at V_CC = 25 V
• 40 W continuous output power:RL = 8 Ω, THD = 10% at V_CC = 25 V
• Wide range single supply operation (10 - 26 V)
• High efficiency (η = 90%)
• Four selectable, fixed gain settings ofnominally 21.6 dB, 27.6 dB, 31.1 dB and33.6 dB
• Differential inputs minimize common-modenoise
• Standby and mute features
• Short-circuit protection
• Thermal-overload protection
• Externally synchronizable
