TDA7491LP
Description
The TDA7491LP 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.
Key Features
- 5 W + 5 W continuous output power: RL = 8 Ω, THD = 10% at VCC = 9 V
- 5 W + 5 W continuous output power: RL = 4 Ω, THD = 10% at VCC = 6.6 V
- Wide range single supply operation (5 V - 14 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
