Integrated Circuit Details

The LH0032 is a general-purpose operational amplifier (op-amp) IC. It's a three-terminal integrated circuit that can amplify and buffer electronic signals. These op-amps are widely used in various analog circuits, including amplifiers, filters, and oscillators. They are known for their relatively low input bias and offset currents and low input capacitance, which makes them suitable for high-speed applications. They operate over a wide supply voltage range and offer excellent stability. The device utilizes a dual-complementary symmetry (DCS) input stage for superior noise performance. [/=h3]
