Overview
The LM224DTB is a single supply quad operational amplifier from the LM324 series, manufactured by ON Semiconductor. It features four independent high-gain amplifiers with internal frequency compensation. The device operates on 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 common mode voltage range that includes ground, low input bias current (maximum 90 nA), and large signal open-loop voltage gain of 100 V/mV. The output voltage swing extends to the negative supply rail.
Feature Summary
- True differential input stage allows common mode voltage to extend to the negative supply.
- Outputs are short-circuit protected for enhanced reliability.
- Internally compensated for stability without external components.
- ESD clamps on inputs increase ruggedness.
Applications
- Transducer amplifiers
- DC gain blocks
- Integrators
Procurement Notes
Verify the specific suffix DTB corresponds to the TSSOP-14 package (Case 948G) as listed in the ordering information. Confirm the operating temperature range is -25°C to +85°C for the LM224 variant. Ensure compliance with RoHS and Pb-Free requirements if applicable to the project specifications.
Selection Notes
Select this component when a low-cost quad op-amp with true differential inputs is required for single-supply applications. It is suitable for designs needing operation down to 3.0 V. Consider the LM224 variant specifically for industrial environments requiring the -25°C to +85°C temperature range compared to commercial grades.
Part Context
The LM224DTB belongs to the LM324 series of single supply quad operational amplifiers. This family is characterized by low cost and distinct advantages over standard types in single supply applications. The series includes variants like LM324, LM2902, and NCV2902, sharing similar pinouts and functional architectures but differing in temperature ranges and automotive qualifications.
