Brief Description TDA1554 is a 4*11W single ended or 2*22W power amplifier IC, with an integrated Class-B output amplifier. TDA1554Q comes in a 17 lead single-in-line package. The internal circuitry contains a 4*11W single ended or 2*22W bridge amplifier. Among all four amplifiers two are inverting and other two are non-inverting. Also, each amplifier has a gain of 20dB (26dB in BTL). TDA1554q also have mute/stand-by feature. TDA1554Q is mainly designed for car radio applications. How to Use? TDA1554 is an amplifier IC and can be used for designing 2*22 watt and 4*11 watt stereo audio power amplifier circuit. The circuit dissipated nearly 28 watt of heat so a good heatsink is necessary. The circuit operates at 12v and 5 amps at full volume. Reducing the volume lowers the current consumption and less heat will be dissipated. Now, as we know we can use this IC for 2*22 watt and 4*11 watt stereo audio power amplifier circuit. The connection diagram for both are given below: 2*22 Watt Stereo Audio Power Amplifier Circuit
