The LM4558M/TR with SOP-8 Differential OpAmps ROHS manufactured by HGSEMI is an audio operational amplifier with two independent, high gain internally frequency compensated inverting or non-inverting amplifier. It features low noise, low distortion and an excellent power supply rejection ratio. Its high output transimpedance makes it ideal for different audio applications including preamplifiers, tone controls, active filters, straight line level signals and additional gain stages. This LM4558M/TR device comes in an 8-pin plastic surface mount SOIC package with a lead-free RoHS, halogen-free finish for improved environmental performance. The device also includes protection against the device open, excessive power supply and thermal overload damage. This device provides improved power supply rejection ratio and low offset voltage drift in addition to its high gain, low noise and low distortion performance.
