LMV934IDRG4

Instrumentation, Op Amps, Buffer Amps Overview

The LMV934IDRG4 is a quad operational amplifier manufactured by Texas Instruments, characterized by low-voltage operation and rail-to-rail input/output capabilities. It operates within a supply voltage range of 1.8 V to 5 V, making it suitable for portable applications powered by single-cell Li-ion or two-cell batteries. The device features a gain bandwidth product of 1.4 MHz at 1.8 V and 1.5 MHz at 5 V, with a typical quiescent current of approximately 100 μA per amplifier. Input offset voltage is specified at a maximum of 7.5 mV across the full temperature range. The component is housed in a 14-pin SOIC package (D) and supports an operating temperature range from -40°C to +125°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix to confirm the package type and reel quantity. The 'IDR' suffix indicates a SOIC-14 package supplied on a reel of 2500 units. Confirm RoHS compliance status and moisture sensitivity level ratings prior to procurement. Ensure the design accounts for the device being marked as obsolete or not recommended for new designs if applicable to long-term availability requirements.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for designs requiring quad amplification in space-constrained environments. It is appropriate for battery-powered systems due to its low supply current and wide input common-mode range. Consider the rail-to-rail output performance when driving loads close to the supply rails. Verify that the 1.4 MHz gain bandwidth meets the frequency response requirements of the application.
