Overview
The LM224DT is a quad low-power operational amplifier manufactured by STMicroelectronics, belonging to the LM224 series. It features four independent high-gain amplifiers with internal frequency compensation. The device supports single supply voltages from 3V to 30V and dual supplies from ±1.5V to ±15V. Key electrical parameters include a gain-bandwidth product of 1.3MHz, a slew rate of 0.4V/µs, and an input bias current of 40nA. It operates within a temperature range of -40°C to +105°C and is housed in a 14-pin SOIC surface-mount package.
Feature Summary
- Quad configuration with four independent high-gain operational amplifiers
- Internal frequency compensation eliminates external component requirements
- Wide single and dual power supply voltage operation capability
- Input common-mode voltage range includes ground potential
Applications
- Industrial signal conditioning circuits
- General-purpose analog processing systems
- Sensor interface applications requiring ground-referenced inputs
Procurement Notes
Verify the specific suffix 'DT' corresponds to the SOIC-14 package and industrial temperature grade (-40°C to +105°C) as documented in official STMicroelectronics datasheets. Confirm RoHS compliance status through current manufacturer documentation. Ensure pinout compatibility matches the target PCB footprint design before integration.
Selection Notes
Select this component for designs requiring multiple op-amps on a single chip with low quiescent current consumption. The wide supply voltage range accommodates various system architectures without level shifting. Verify that the 7mV maximum input offset voltage meets the precision requirements of the specific application circuit.
Part Context
This part belongs to the LM224 family, which shares architectural similarities with the LM124 and LM324 series. These devices are standard general-purpose quad operational amplifiers widely used in consumer and industrial electronics. The LM224 specifically denotes the commercial/industrial temperature variant distinct from military or extended grade counterparts.
Replacement Considerations
LM324DT: Pin-compatible alternative with potentially different offset voltage specifications. LM124DT: Similar architecture but may differ in temperature rating or reliability standards. Verify electrical parameter equivalence and package dimensions before substitution.
