Overview
TDA7491HV Datasheet 20 W + 20 W dual BTL class-D audio amplifier PowerSSO-36 exposed pad up PowerSSO-36 with exposed pad down Features • 20 W + 20 W continuous output power: – RL = 8 Ω, THD = 10% at VCC = 18 V • Wide-range single-supply operation (5 - 18 V) • High efficiency (η = 90%) • Four selectable, fixed gain settings of nominally 20 dB, 26 dB, 30 dB and 32 dB • Differential input minimize common-mode noise • No ‘pop’ at turn-on/off • Standby and mute features • Short-circuit protection • Thermal overload protection • External synchronisation Description The TDA7491HV is a dual BTL class-D audio amplifier with single power supply designed for LCD TVs and monitors.
Thanks to the high efficiency and exposed-pad-up (EPU) and down (EPD) packages, no separate heatsink is required.
The TDA7491HV is pin-to-pin compatible with the TDA7491P and TDA7491LP.
