在音频应用中往往需要把单端输入变换成平衡输出对。ＤＲＶ１３４和ＤＲＶ１３５就是为这种应用而设计的差分输出放大器。这种平衡音频驱动器由具有片上精密电阻器的高性能运放组成（见图１）。它们完全符合高性能音频应用，具有特别好的ａｃ特性，这包括低失真（在１ｋＨｚ为?
In audio applications it is often necessary to transform single-ended inputs into balanced output pairs. The DRV134 and DRV135 are differential output amplifiers designed for this application. This balanced audio driver consists of a high-performance op amp with an on-chip precision resistor (see Figure 1). They are fully compliant with high performance audio applications and have exceptionally good ac characteristics, including low distortion (at 1kHz?
