TDA7491HV Audio Amplifiers are dual Bridge-Tied Load (BTL) class-D audio amplifiers with a single power supply designed for LCD TVs and monitors. Features include Short-circuit protection, thermal overload protection, and external synchronization. These audio amplifiers are pin-to-pin compatible with the TDA7491P and TDA7491LP amplifiers.
20W + 20W continuous output power:
RL = 8Ω, THD = 10% @ VCC = 18V
Wide-range single-supply operation (5V - 18V)
High efficiency (η = 90%)
Four selectable, fixed gain settings of nominally 20dB, 26dB, 30dB, and 32dB
