The TDA1013B is an audio power amplifier integrated circuit that features a DC volume control circuit with a logarithmic curve. It offers a control range of up to 80dB, making it ideal for precise sound adjustment. This IC operates on a wide supply voltage range from 10V to 40V, delivering output power between 4W and 10W. Its design includes a separate preamplifier and power amplifier section, allowing for greater flexibility in audio applications. The device supports a power gain of up to 38dB at 18V supply voltage and 8Ω load. It requires minimal external components, which simplifies the overall design. Additionally, it generates very little heat, reducing the need for large heat sinks. The TDA1013B also eliminates switch-on/off noise, ensuring a smooth user experience. It comes in a compact, single-row 9-pin plastic package (SIL) for easy integration into various systems.
