Audio Line Driver Circuit

The response graph shows the measured frequency response with the differential feed a balanced line driver figure 1 and receiver figure 2.

Audio line driver circuit.

Figure 4 overall frequency response of differential feed and both circuits. The signal is 1db down at 10hz and 30khz which is pretty good considering the overall simplicity of the circuits. Audio systems by eliminating power line hum rf interference voltage drops and other externally generated noise commonly encountered with long audio cable runs. The 25 mhz bandwidth low distortion and high output current of the ic makes it possible to drive medium impedance loads at a high level of modulation.

This is the circuit diagram of a two channel audio line driver using the high performance dual opamp ic tsh22 from st microelectronics. The 25 mhz bandwidth low distortion and high output current of the ic makes it possible to drive medium impedance loads at a high level of modulation. Here is the schematic diagram. By walt jung and adolfo garcia download pdf.

Line drivers will enhance your audio signal output coming from any factory or aftermarket head unit receiver. They help increase the volume output without over driving your source or amplifier. Balanced line driver that s 1646 balanced line driver is a very simple ic to implement requiring very few external components. Op amps in line driver and receiver circuits part 2.

Choose from our large selection of quality name brand line drivers. Integrated operational amplifiers are not always suitable for applications where a high signal level u o v rms is required for driving a relatively low impedance z 50 600 ω the amplifier described here is eminently suitable as a high dynamic range line driver of power buffer in public address systems and af. A stereo pair will fit on the d4 prototyping board with room to spare. Excellent rejection of common mode noise and offset errors is achieved by laser trimming of the onboard resistors assuring high gain accuracy.

Audio line driver this preamplifier has a low output impedance and is designed to drive long cables allowing you to listen to a remote music source without having to buy expensive screened cables. Audio line driver circuit. So that the lt1206 can also be used for audio applications. A complete schematic including rfi protection and power supply bypassing is shown in fig.

Posted by circuit diagram in amplifier wiring diagrams. Ic sockets are optional. In this article we consider audio line drivers and receivers. This is the circuit diagram of a two channel audio line driver using the high performance dual opamp ic tsh22 from st microelectronics.

The first article in this series analog dialogue 26 2 covering general line driving and buffer design considerations gave examples of video line driver and receiver designs.
