LP324MT

Instrumentation, Op Amps, Buffer Amps Overview

The LP324MT/NOPB is a quad operational amplifier manufactured by Texas Instruments, housed in a 14-pin TSSOP package. It features a gain-bandwidth product of 100 kHz and a slew rate of 50 mV/us. The device operates on a single supply voltage ranging from 3 V to 32 V, or dual supplies of ±1.5 V to ±16 V. Input offset voltage is typically 4 mV with an input bias current of 10 nA. Each channel provides an output current of 10 mA while consuming only 21 µA per channel. The common-mode rejection ratio is 90 dB, and the input voltage noise density is 80 nV/√Hz. It supports rail-to-rail input operation within the commercial temperature range of 0°C to +70°C.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Quad configuration providing four independent low-power operational amplifiers in a compact surface-mount package.
• Rail-to-rail input capability allows signal processing near the negative supply rail for enhanced dynamic range.
• Ultra-low quiescent current consumption enables extended battery life in portable and energy-efficient designs.

Instrumentation, Op Amps, Buffer Amps Applications

• Battery-powered sensor interfaces requiring minimal power draw
• Signal conditioning circuits for transducers and measurement systems
• General-purpose analog processing in consumer electronics

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix (e.g., NOPB) against the datasheet to confirm lead-free compliance and exact electrical specifications. Ensure the TSSOP-14 package matches the PCB footprint. Confirm the commercial temperature grade (0°C to +70°C) aligns with the application environment requirements before finalizing procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when low power consumption is critical alongside moderate bandwidth requirements. The rail-to-rail input feature distinguishes it from standard bipolar op-amps that cannot handle signals near the negative rail. Compare against the LM324 if higher speed is needed, or the LPV324 if wider temperature ranges are required.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the LP324 family of micropower quad operational amplifiers from Texas Instruments. It serves as a low-cost, low-power alternative to the industry-standard LM324, offering improved input characteristics and lower current consumption while maintaining similar pinouts and functionality for easy design upgrades.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

LP324MTX/NOPB is a tape-and-reel variant of the same device. LP324DR offers identical electrical performance in an SOIC-14 package. LM324AN/NOPB is a higher-speed alternative but consumes significantly more current.
