TDA7492P is a 25-watt + 25-watt dual BTL class-D audio amplifier with wide-range single-supply operation, high efficiency, selectable fixed gain settings, differential inputs, standby and mute features, short-circuit protection, thermal overload protection, etc.
The document describes the TDA7492P, a dual bridge-tied load (BTL) Class-D audio amplifier designed for LCD TVs and monitors. It delivers 25 watts per channel of continuous output power at THD = 10% with a supply voltage of 20 V and an 8 Ω load. The device operates on a wide single-supply range from 8 V to 26 V.
| Output power (typical) | 25 W + 25 W |
|---|---|
| Supply voltage range | 8 V to 26 V |
| Efficiency | 90% |
The device provides 25 watts per channel at THD = 10% with a 20 V supply and 8 Ω load.
No, thanks to its high efficiency and exposed-pad-down package, no heatsink is required.
The amplifier offers four selectable fixed gains: 21.6 dB, 27.6 dB, 31.1 dB, and 33.6 dB.
