LMR822FJ-GE2

Instrumentation, Op Amps, Buffer Amps Overview

The LMR822FJ-GE2 is a dual-channel operational amplifier from ROHM Semiconductor, designed for low supply current and full output swing applications. It operates within a voltage range of 2.5 V to 5.5 V with a typical circuit current of 650 uA. Key electrical parameters include a gain-bandwidth product of 5.5 MHz, a slew rate of 2 V/us, and an input offset voltage of 1 mV. The device features an input bias current of 40 nA, an output current capability of 45 mA per channel, and a common-mode rejection ratio of 72 dB. It is housed in an SOP-8 package and functions across a temperature range of -40 C to +85 C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix GE2 indicates RoHS compliance and lead-free status as per manufacturer standards. Confirm the SOP-8 package variant matches the footprint requirements of the target PCB design. Ensure the operating temperature range of -40 C to +85 C aligns with the environmental conditions of the intended application. Cross-reference the datasheet revision date to ensure all electrical parameter limits are current.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a dual-channel op amp with low quiescent current and rail-to-rail output is required under single supply voltages. Compare against the LMR822FV-GE2 if SSOP-8 packaging is preferred over SOP-8. Consider the 5.5 MHz bandwidth and 2 V/us slew rate for moderate-speed signal conditioning tasks. Evaluate the 1 mV input offset voltage for accuracy requirements in low-gain configurations.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the LMR Series of low supply current operational amplifiers manufactured by ROHM Semiconductor. The series focuses on providing high performance in low-power environments, making it suitable for portable electronics. The LMR822FJ-GE2 specifically offers two channels in a surface-mount package, balancing power efficiency with sufficient drive capability for general-purpose analog applications.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The LMR822FV-GE2 serves as a direct functional substitute with identical electrical characteristics but utilizes an SSOP-8 package instead of SOP-8. Verify pin compatibility and physical footprint differences before substitution. No other cross-model replacements are confirmed in the provided documentation.
