Overview
The LM224DR2G is a quad operational amplifier manufactured by onsemi, housed in a SOIC-14 package. It operates from a single supply voltage ranging from 3.0 V to 32 V or split supplies of ±1.5 V to ±16 V. The device features an input common mode voltage range that includes the negative supply and ground. Electrical characteristics include a maximum input bias current of 90 nA, a typical power supply current of 1.2 mA at 5.0 V, and a large signal open-loop voltage gain of 100 V/mV. The output stage provides short-circuit protection and can source up to 40 mA.
Feature Summary
- True differential input stage allows common mode voltage to extend to the negative supply rail.
- Outputs are internally short-circuit protected against ground faults.
- Internally frequency compensated for stability without external components.
- Low quiescent current consumption independent of supply voltage magnitude.
Applications
- Transducer amplifiers
- DC gain blocks
- Integrators
Procurement Notes
Verify the specific ordering suffix 'R2G' corresponds to the tape and reel packaging configuration required for automated assembly processes. Confirm the component meets RoHS compliance standards as indicated in the manufacturer's documentation. Ensure the SOIC-14 package dimensions align with the target PCB footprint design constraints.
Selection Notes
Select this component when applications require operation from a single low-voltage supply down to 3.0 V. The wide common mode input range simplifies circuit design by eliminating the need for external biasing networks. Verify that the required operating temperature range falls within the -25°C to +85°C specification limits defined for the LM224 series.
Part Context
This part belongs to the LM324 series family of low-cost quad operational amplifiers. The LM224 variant specifically denotes the industrial temperature grade (-25°C to +85°C), distinguishing it from the commercial LM324 (0°C to +70°C) and automotive NCV2902 grades. All variants share identical pinouts and electrical performance profiles.
