LMR324FVJ-E2

Instrumentation, Op Amps, Buffer Amps Overview

The LMR324FVJ-E2 is a four-channel ground sense low power operational amplifier manufactured by ROHM Semiconductor. It operates within a supply voltage range of 2.7 V to 5.5 V, drawing a typical quiescent current of 410 uA. Key electrical specifications include a gain-bandwidth product of 3 MHz, a slew rate of 1 V/us, and an input offset voltage of 1 mV. The device provides a channel output current of 70 mA and features a common-mode rejection ratio of 65 dB with an input voltage noise density of 39 nV/sqrt Hz. It is housed in a TSSOP-14 package and supports an operating temperature range from -40 C to +85 C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix E2 against the manufacturer's latest datasheet to confirm pinout compatibility and RoHS status. Ensure the TSSOP-14 package dimensions match your PCB footprint requirements. Confirm that the operating temperature range meets your environmental design constraints before finalizing procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when single-supply operation near ground is required alongside low power constraints. Compare the 3 MHz bandwidth and 410 uA quiescent current against higher-speed or lower-power alternatives in the LMR series. Verify that the 70 mA output current meets load drive requirements for your specific application circuit.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the LMR324 series of low power operational amplifiers from ROHM Semiconductor. The series includes variants such as LMR324FJ-GE2 and LMR324FV-GE2, which share similar electrical characteristics but may differ in package type or manufacturing revision. The LMR324FVJ-E2 specifically utilizes the TSSOP-14 package format.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Check for direct substitutes like LMR324FJ-GE2 or LMR324FV-GE2, ensuring package compatibility. Verify that any replacement maintains the ground sense input feature and similar electrical parameters.
