The OP220 is a monolithic dual operational amplifier that can be used either in single or dual supply operation. Its low offset voltage and input offset voltage tracking (as low as 1.0 mV/∞C) make it the first micropower precision dual operational amplifier. Its excellent specifications make it very attractive in portable applications.
The document describes the OP220 as a monolithic dual operational amplifier designed for single or dual supply operation. Key features include excellent temperature coefficient of input offset voltage (TCVos) matching, low input offset voltage, and very low supply current suitable for battery-powered applications.
The datasheet provides comprehensive electrical specifications for various grades (A/E, F, C/G, N), including input offset voltage, bias currents, common-mode rejection ratio (CMRR), power supply rejection ratio (PSRR), bandwidth, and slew rate. It also includes absolute maximum ratings, pin configurations for different package types, ordering guides, and typical performance characteristics graphs.
