LM224DR2G

Overview

The LM224DR2G is a low-power quad operational amplifier manufactured by onsemi, housed in a 14-pin SOIC package. It operates within a single supply voltage range of 3.0 V to 32 V or split supplies of ±1.5 V to ±16 V. The device features four internally compensated amplifiers with true differential inputs that extend to the negative supply rail. Key electrical specifications include a gain-bandwidth product of 1 MHz, a typical input offset voltage of 5 mV at 25°C, and an input bias current of up to 150 nA. It supports a quiescent current of approximately 1.2 mA per amplifier and provides short-circuit protected outputs capable of sourcing up to 40 mA.

Feature Summary

• True differential input stage allows common mode voltage range to include the negative power supply, eliminating the need for external biasing components in many single-supply applications.
• Outputs are short-circuit protected, enhancing device ruggedness during fault conditions without affecting normal operation.
• Internally frequency compensated design simplifies circuit implementation by removing the requirement for external compensation capacitors.
• Input ESD clamps increase device robustness against electrostatic discharge events while maintaining standard operational characteristics.

Applications

• Transducer amplifiers for signal conditioning
• DC gain blocks in instrumentation circuits
• All classic op amp circuits adaptable to single supply operation

Procurement Notes

Verify the specific suffix DR2G corresponds to the SOIC-14 package and tape & reel shipping configuration. Confirm the operating temperature range matches the LM224 specification (-25°C to +85°C) rather than the commercial LM324 variant. Ensure RoHS compliance requirements align with the Pb-Free designation indicated in the ordering information.

Selection Notes

Select this component when single-supply operation down to 3 V is required alongside high voltage tolerance up to 32 V. Consider the LM224 variant over the LM324 if extended industrial temperature performance below 0°C is necessary. Evaluate the 1 MHz bandwidth and 600 mV/us slew rate against application speed requirements before finalizing the design.

Part Context

This part belongs to the LM324 series family, which includes LM324, LM224, LM2902, and NCV2902 devices. These are low-cost quad operational amplifiers designed for versatile use in various analog signal processing tasks. The LM224 specifically denotes the industrial temperature grade version within this lineup.
