Audio Balanced Line Driver Ic

Op amps in line driver and receiver circuits part 2.

Audio balanced line driver ic.

Open in new find other audio line drivers description. U1 is a balanced line driver ic. 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. The drv134 and drv135 are differential output amplifiers that convert a single ended input to a balanced output pair.

This balanced audio driver consists of high performance op amps with on chip precision resistors. They are fully specified for high performance audio applications. They help increase the volume output without over driving your source or amplifier. The inductance of ferrite beads f1 f2 react with the capacitance of c5 c6 to shunt rfi noise to the chassis away from the audio circuit.

Line drivers will enhance your audio signal output coming from any factory or aftermarket head unit receiver. Based on a high performance fully differential op amp and laser trimmed thin film resistors both exhibit low noise and distortion high slew rate and wide output swing. In this article we consider audio line drivers and receivers. The mini board converts unbalance audio signal into balance audio signal the project is based on ssm2142 or drv135 ic which are differential output amplifier that converts a single ended audio signal input to a balanced output pair.

By walt jung and adolfo garcia download pdf. 1646 ti drv134 and ssm2142 are all pin compatible. Choose from our large selection of quality name brand line drivers. Open in new find other audio line drivers description.

The drv134 and drv135 are differential output amplifiers that convert a single ended input to a balanced output pair. The parts are stable when driving difficult loads and have short. These balanced audio drivers consist of high performance op amps with on chip precision resistors.
