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.主な特徴
- 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
