Brand: Fairchild
The Fairchild 542 is a quadrical amplifier built using bipolar junction transistors (BJTs) manufactured by Fairchild Semiconductor. It operates on a supply voltage range of 4.5V to 36V and provides four independent NPN transistors inside a single integrated circuit (IC). Each of these transistors can be utilized as a switching transistor or amplifier for small-signal applications. The Fairchild 542 offers a wide bandwidth, low noise, and high gain making it a suitable choice for various analog applications such as audio amplifiers, instrumentation amplifiers, and voltage regulators. It is also internationally recognized as a RoHS-compliant, lead-free, and environment-friendly product.
