Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix JE2 against the manufacturer's datasheet to confirm the SOP-J14 package variant. Ensure the component meets RoHS compliance requirements for your target market. Confirm that the industrial temperature range aligns with your environmental specifications. Cross-reference the ordering code with official ROHM documentation to avoid substitution errors during procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when full input and output voltage swing is required from a single low-voltage supply. It is appropriate for designs prioritizing low power consumption alongside moderate bandwidth. Compare its 1.5 MHz gain-bandwidth product against higher-speed alternatives if signal fidelity at elevated frequencies is critical. Ensure the 90 mA output drive capability meets the load requirements of the application circuit.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the LMR series of low-voltage operational amplifiers from ROHM Semiconductor. The series is designed for portable applications requiring efficient power usage. The LMR934 variant specifically integrates four independent amplifier channels within a compact footprint, distinguishing it from dual-channel or single-channel counterparts in the same family.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The LMR934FV-GE2 is a documented substitute offering identical electrical characteristics but utilizing an SSOP-14 package instead of the SOP-J14 form factor. Verify pin compatibility and thermal performance before substituting.
