LMV822MX

Instrumentation, Op Amps, Buffer Amps Overview

The LMV822MX is a dual operational amplifier from the LMV82x series manufactured by Texas Instruments. It operates on a single supply voltage ranging from 2.5 V to 5.5 V with a maximum operating supply current of 400 μA at 5 V. The device features a gain bandwidth product of 5.5 MHz and a slew rate of 2 V/μs. Input offset voltage is specified at a maximum of 3.5 mV, while input bias current is limited to 100 nA. Common mode rejection ratio ranges from 72 dB to 90 dB. The output current per channel is rated at 16 mA. It utilizes an SOIC-Narrow-8 package and supports an extended operating temperature range from -40°C to +125°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the manufacturer designation as Texas Instruments, as National Semiconductor was acquired. Confirm the specific suffix MX indicates the SOIC-8 surface mount package variant. Ensure the NOPB designation is present if RoHS compliance is required. Cross-reference part numbers carefully due to historical branding changes.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when rail-to-rail output is required alongside a gain bandwidth product exceeding standard LMV321 devices. It is appropriate for designs needing low offset voltage and high common mode rejection in single-supply systems. Consider the extended temperature range if the application involves automotive or industrial environments.

Instrumentation, Op Amps, Buffer Amps Part Context

The LMV822MX belongs to the LMV82x family, which includes single (LMV821), dual (LMV822), and quad (LMV824) variants. This family is designed to outperform industry standards like the LMV321, particularly regarding gain bandwidth. Other members such as the LMV820 include shutdown features not present in the standard LMV822.
