The TDA1013B is a high-performance audio power amplifier IC that features a DC volume control circuit with a logarithmic response. It offers a control range of up to 80dB, making it ideal for precise sound adjustment. This IC operates over a wide supply voltage range (10V to 40V), and delivers output power between 4W and 10W, making it an excellent choice for TV receivers and other audio applications. It includes a built-in preamplifier and power amplifier stage, along with DC volume control that allows for smooth and quiet adjustments within a voltage range of 2V to 7V. With a maximum power gain of 38dB at 18V supply and 8Ω load, it requires minimal external components, ensuring a compact and efficient design. Additionally, it produces low heat and eliminates switching noise, enhancing overall performance and user experience. The device comes in a single-row 9-pin plastic package (SIL type), offering a simple and reliable solution for various audio systems.
