The MS8552 is a precision opamp ROHS manufactured by Ruimeng. It is a SOP-8 package, and is designed for use in audio and instrumentation applications. The MS8552 has a number of features, including low noise, high bandwidth, low input bias current, low input offset voltage, high output full swing, and short-circuit protected output. It is compatible with both TTL and CMOS logic levels. The operation temperature range is from -40 °C to +85 °C, and it has a high input impedance of 100 MO. It has a low impedance output allowing direct connection to an ADC, DAC, or other component. The MS8552 is also RoHS compliant.
