The MS8311 is a precision single-operational amplifier with SOT-23 (Small Outline Transistor) package and ROHS (Restrictions on Hazardous Substances) compliance. It is manufactured by Ruimeng and has a slew rate of 0.6 V/ms with a voltage gain of 1000, making it suitable for high-accuracy applications such as medical and industrial instrumentation. The device comes in a 3-pin SOT-23 package and requires a single supply voltage of 2.7V to 36V for operation. It features low distortion, low input bias current, wide bandwidth, low offset voltage, and high input impedance. This makes it suitable for signal conditioning, filtering, and precision signal processing in various end-user setups.
