LM224DG

Overview

The LM224DG is a single supply quad operational amplifier manufactured by onsemi. It features four independent, high-gain amplifiers with internal frequency compensation. The device operates from a single power supply ranging from 3.0 V to 32 V or split supplies of ±1.5 V to ±16 V. Key electrical characteristics include an input bias current of up to 90 nA and an input offset voltage maximum of 7.0 mV at elevated temperatures. The operating ambient temperature range is specified from -25°C to +85°C.

Feature Summary

• True differential input stage allows common mode voltage range to extend to the negative supply rail.
• Outputs are short-circuit protected for enhanced reliability under fault conditions.
• ESD clamps integrated on inputs increase device ruggedness without affecting operation.
• Industry standard pinouts facilitate easy integration into existing designs.

Applications

• Transducer amplifiers
• DC gain blocks
• Integrators

Procurement Notes

Verify that the ordering suffix 'DG' corresponds to the SOIC-14 package and lead-free construction as defined in the official datasheet. Confirm the specific temperature grade matches the required application environment, as suffixes denote distinct operating ranges within the series. Ensure compliance with RoHS standards if applicable to the target market regulations.

Selection Notes

Select this component when a low-cost quad op-amp with true differential inputs is required for single-supply applications. The LM224DG offers an extended industrial temperature range compared to commercial variants. Consider the internal compensation and wide supply voltage flexibility when designing circuits that need to operate across varying power levels without external biasing components.

Part Context

This part belongs to the LM324 series family, which includes multiple variants differentiated by temperature ratings and performance grades. The LM224 variant specifically targets industrial environments with a wider operating temperature span than the standard LM324. All members share the same fundamental architecture and pinout configuration.
