The TDA7491P 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-down (EPD) package no separate heatsink is required.
Furthermore, the filterless operation allows a reduction in the external component count.
The TDA7491P is pin-to-pin compatible with the TDA7491LP and TDA7491HV.
- 10 W + 10 W continuous output power:RL= 6 Ω, THD = 10% at VCC = 11 V
- 9.5 W + 9.5 W continuous output power:RL= 8 Ω, THD = 10% at VCC = 12 V
- Wide range single supply operation (5 V - 18 V)
- High efficiency (η = 90%)
- Four selectable, fixed gain settings of nominally 20 dB, 26 dB, 30 dB and 32 dB
- Differential inputs minimize common-mode noise
- Filterless operation
- No ‘pop’ at turn-on/off
- Standby and mute features
- Short-circuit protection
- Thermal overload protection
- Externally synchronizable
