KST9014L with Transistors (NPN/PNP) SOT23 RoHS is a low-noise, high-gain, low-dropout two-stage amplifier manufactured by KEXIN. It is designed to amplify and boost a wide range of frequencies and is ideal for use in audio applications. The device features two transistors, an NPN and a PNP, which makes it suitable for a wide range of circuit topologies, such as direct-coupled, common source/gate, and common collector/gate. The KST9014L also has an integrated ESD protection circuit, making it resistant to electrostatic discharge. It is RoHS compliant and is packaged in the small SOT23 form factor.
