Overview
The LM224KD is a quad operational amplifier from Texas Instruments, featuring four independent high-gain frequency-compensated circuits. It operates on single supplies of 3 V to 32 V or dual supplies of ±1.5 V to ±16 V. Key electrical parameters include a gain-bandwidth product of 1.2 MHz, a slew rate of 0.5 V/µs, and an input offset voltage of 5 mV. The device draws 1.4 mA of supply current and provides 20 mA output current per channel. It is housed in a 14-SOIC package with an operating temperature range of -25°C to +85°C.
Feature Summary
- Four independent high-gain frequency-compensated operational amplifiers
- Designed for operation from a single supply over a wide voltage range
- Low supply-current drain independent of the magnitude of the supply voltage
Applications
- Transducer amplifiers
- DC amplification blocks
- Single-supply-voltage systems
Procurement Notes
Verify the specific suffix 'K' against official documentation to confirm ESD protection ratings. Confirm the 'D' suffix indicates the SOIC-14 surface-mount package. Ensure the component matches the required industrial temperature range and electrical specifications before integration.
Selection Notes
Select this component for applications requiring multiple op-amps in a single package with low power consumption. It is suitable for digital systems using standard 5-V supplies without needing additional negative rails. Consider the 1.2 MHz bandwidth and 0.5 V/µs slew rate for signal conditioning tasks.
Part Context
The LM224 belongs to the LMx24 family of low-power quad operational amplifiers. This series is designed to replace older multi-op-amp solutions by offering integrated frequency compensation and simplified single-supply operation. The device serves as a versatile building block for analog signal processing in cost-sensitive electronics.
