Analog Devices OP221 Dual Low Power Operational Amplifier Datasheet
The document describes the OP221 as a monolithic dual operational amplifier suitable for use in either single or dual supply configurations. Key features include excellent temperature coefficient of input offset voltage match, maximum low input offset voltage, and maximum low supply current, making it ideal for battery or unregulated power supply applications.
The datasheet provides comprehensive electrical specifications, including input offset voltage, bias currents, common-mode rejection ratio, and power supply rejection ratio. It also includes typical performance characteristics graphs covering open-loop gain, phase margin, slew rate, noise density, and output swing versus frequency and temperature.
