    The SY2A54024 is a differential amplifier designed for car radio applications. It is especially useful in applications with long connections between signal sources and amplifiers where ground noise elimination is crucial. The device utilizes an instrumentation amplifier topology with 0dB gain, ensuring high input impedance and a high common-mode rejection ratio (CMRR). The SY2A54024 achieves a typical common-mode rejection of 106dB, maintaining its effectiveness even with mismatched source impedances.

    The SY2A54024 device is designed to operate at a high level of performance in audio line-receiver applications with minimal external components. Figure 1 illustrates the use of SY2A54024 in professional audio applications. In these applications, the line receiver recovers a differential audio signal that may have been affected by considerable common-mode noise.

    The SY2A54024 is available in a compact TSSOP14 package.
