OPA4340UA

Instrumentation, Op Amps, Buffer Amps Overview

The OPA4340UA is a quad operational amplifier from Texas Instruments featuring rail-to-rail input and output capabilities. It operates within a supply voltage range of 2.7 V to 5.5 V, consuming 750 uA of operating current. Key electrical specifications include a gain-bandwidth product of 5.5 MHz, a slew rate of 6 V/us, and an input offset voltage of 500 uV. The device provides 92 dB common-mode rejection ratio and 25 nV/sqrt Hz input voltage noise density. It supports 50 mA per channel output current and functions reliably across temperatures from -40 C to +85 C in a SOIC-14 package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix to confirm the packaging format, as the base part number may be available in tubes or reels. Ensure the component meets RoHS requirements if mandated by your design standards. Confirm that the SOIC-14 package dimensions align with your PCB footprint constraints before finalizing procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a quad amplifier with rail-to-rail I/O is required under a 5.5 V maximum supply. It is appropriate for designs prioritizing low power consumption alongside moderate bandwidth needs. Consider the SOIC-14 package availability and thermal characteristics relative to your board layout and ambient temperature conditions.

Instrumentation, Op Amps, Buffer Amps Part Context

This device belongs to the OPA4340 series of low-power, precision operational amplifiers. It is designed for applications requiring multiple channels in a compact form factor. The series emphasizes efficiency and signal integrity in single-supply environments, distinguishing it from higher-voltage or dual-channel variants within the manufacturer's portfolio.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Check for OPA4340UAG4 or OPA4340EA/250G4 for alternative packaging options such as tape-and-reel or SSOP formats. Verify pinout compatibility and electrical parameter equivalence before substituting.
