Product Details

Audio Amp 2 click is a highly efficient class D audio amplifier, using the TDA7491, a dual BTL class-D audio amplifier IC, capable of delivering up to 20W to 8Ω load. This amplifier IC features high-efficiency output stage drivers and clever design, allowing it to deliver a reasonably high power to the connected speakers, using only GND polygon on the PCB for heat dissipation. In the BTL topology, the output DC blocking capacitors are not required. This allows for simpler design and lower power losses, especially with no input signal. The TDA7491 amplifier IC is equipped with a set of protection features, that allow reliable operation.

20 W + 20 W continuous output power: RL =8 Ω, THD = 10% at VCC = 18 V
Wide-range single-supply operation (5 V - 18 V)
High efficiency (Ƞ = 90%)
Four selectable, fixed gain settings of
nominally 20 dB, 26 dB, 30 dB and 32 dB
Differential inputs minimize common mode noise
No ’pop’ at turn-on/off
Standby and mute features
Short-circuit protection
Thermal overload protection
Externally synchronizable
