LM324APT

Instrumentation, Op Amps, Buffer Amps Overview

The LM324APT is a low-power, low input bias current quad operational amplifier manufactured by STMicroelectronics. It consists of four independent, high-gain amplifiers with internal frequency compensation. The device operates from a single power supply over a wide voltage range (3 V to 30 V) or split supplies (±1.5 V to ±15 V). Key electrical parameters include a gain-bandwidth product of 1.3 MHz, a maximum input offset voltage of 2 mV, and an output current per channel of 40 mA. It features a typical supply current of 1.5 mA and operates within a temperature range of 0°C to 70°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'APT' corresponds to the 14-TSSOP package and commercial temperature grade (0°C to 70°C) as defined in the official datasheet. Confirm RoHS compliance status and ensure the ordering quantity matches the manufacturer's standard packaging specifications for this part number.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select the LM324APT when a general-purpose quad op-amp is required for single-supply applications. It is suitable for designs needing low power consumption and wide common-mode input voltage range including ground. Ensure the application does not require industrial temperature ratings or shutdown functionality, which are available in other variants.

Instrumentation, Op Amps, Buffer Amps Part Context

The LM324APT belongs to the LMx24 family of low-power quad operational amplifiers. This family includes variants such as the LM124, LM224, and LM324, differentiated primarily by temperature ranges and performance grades. The 'A' suffix typically denotes improved specifications like lower offset voltage compared to standard versions.
