LM324BIDR

Instrumentation, Op Amps, Buffer Amps Overview

The LM324BIDR is a quad operational amplifier manufactured by Texas Instruments, housed in a 14-pin SOIC surface-mount package. It operates within a supply voltage range of 3V to 36V and supports dual supplies from ±1.5V to ±18V. The device features a gain-bandwidth product of 1MHz and a slew rate of 0.5V/µs. Key electrical parameters include a maximum input offset voltage of 3mV, an input bias current of 50nA, and a quiescent current of 240µA per amplifier. It functions across an industrial temperature range of -40°C to +85°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify that the specific suffix 'IDR' corresponds to the industrial temperature grade (-40°C to +85°C) and SOIC-14 package configuration. Confirm the component is the B-version with the specified 3mV max offset voltage. Ensure compatibility with existing PCB footprints designed for standard SOIC packages. Cross-reference the manufacturer datasheet for exact pinout and thermal characteristics before finalizing procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when replacing older LM324 versions to benefit from lower offset voltage and higher ESD tolerance. It is suitable for cost-sensitive designs requiring high-voltage operation up to 36V. The low quiescent current makes it appropriate for battery-powered or energy-efficient systems. Verify that the industrial temperature range meets the environmental requirements of the target application.
