LP324DRG4

Instrumentation, Op Amps, Buffer Amps Overview

The LP324DRG4 is a quad ultra-low-power operational amplifier manufactured by Texas Instruments. It features four independent amplifiers in a single package, designed for low-voltage applications. Key electrical parameters include a gain-bandwidth product of 100 kHz and a slew rate of 50 mV/us. The input offset voltage is specified at 4 mV, with an input bias current of 10 nA. It operates on a supply voltage range from 3 V to 32 V, drawing an operating supply current of 85 uA. Each channel provides an output current of 10 mA. The device supports rail-to-rail input and offers a common-mode rejection ratio of 90 dB. It is housed in a SOIC-14 surface-mount package.

Instrumentation, Op Amps, Buffer Amps Applications

• Battery-powered sensor interfaces
• Low-voltage signal conditioning circuits
• Portable instrumentation systems

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific datasheet revision for the LP324DRG4 part number to ensure alignment with design requirements. Confirm that the SOIC-14 package dimensions match the PCB footprint. Check for any lead-free or RoHS compliance documentation if required by regulatory standards. Ensure the operating temperature range meets the environmental conditions of the target application.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when low quiescent current is critical compared to standard general-purpose op amps like the LM324. The LP324 offers lower power but reduced bandwidth and slew rate relative to higher-speed alternatives. Consider the rail-to-rail input feature if signal swings approach the supply rails. Verify that the 10 mA output current per channel is sufficient for the load requirements.

Instrumentation, Op Amps, Buffer Amps Part Context

The LP324 series belongs to Texas Instruments' portfolio of low-power operational amplifiers. It serves as a power-efficient alternative to the legacy LM324 family. The 'DRG4' suffix indicates a tape-and-reel packaging format with lead-free composition, distinguishing it from other packaging variants like the DR or D packages.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The LM324DRG4 is a functional substitute within the same manufacturer's lineup, though it exhibits higher power consumption and different electrical characteristics. Other quad op amps may require verification of pin compatibility and performance parameter alignment.
