LM224DTBR2G

Overview

The LM224DTBR2G is a low-power quad operational amplifier manufactured by onsemi, featuring true differential inputs and internal frequency compensation. It operates from a single power supply ranging from 3.0 V to 32 V or split supplies of ±1.5 V to ±16 V. The device includes four amplifiers per package with short-circuit protected outputs and an input common mode voltage range that extends to the negative supply. Electrical characteristics include a maximum input bias current of 150 nA, a typical input offset voltage of 5.0 mV at 25°C, and a large signal open-loop voltage gain of 100 V/mV. It is housed in a TSSOP-14 package.

Feature Summary

• Features true differential input stages allowing operation with input common mode voltage extending to the negative supply rail.
• Includes internally compensated amplifiers designed for stable performance across wide power supply ranges.
• Outputs are short-circuit protected to enhance device reliability during fault conditions.
• Provides industry standard pinouts compatible with existing designs.

Applications

• Transducer amplifiers
• DC gain blocks
• Integrators

Procurement Notes

Verify the specific suffix DTBR2G corresponds to the TSSOP-14 package and tape & reel shipping configuration. Confirm the operating temperature range matches the LM224 specification (-25°C to +85°C) rather than commercial variants. Ensure RoHS compliance requirements align with project standards before finalizing procurement orders.

Selection Notes

Select this component when single-supply operation down to 3.0 V is required alongside high input impedance. The LM224 variant offers extended temperature capabilities compared to standard LM324 versions. Consider the TSSOP-14 package for applications requiring higher pin density than SOIC-14 options while maintaining surface mount compatibility.

Part Context

This part belongs to the LMx24 series of low-cost quad operational amplifiers. It shares architectural similarities with the LM324 and LM2902 but is distinguished by its specific industrial temperature rating and package configuration. The series utilizes a two-stage amplifier design with reduced transconductance to minimize chip area while maintaining adequate gain-bandwidth product.
