OPA340NA/250

Instrumentation, Op Amps, Buffer Amps Overview

The OPA340NA/250 is a single-channel, low-offset voltage operational amplifier from the Texas Instruments MicroAmplifier series. It operates on a single supply voltage ranging from 2.5 V to 5.5 V and features rail-to-rail input and output capabilities. Key electrical specifications include a gain-bandwidth product of 5.5 MHz, a slew rate of 6 V/µs, and an input offset voltage as low as 150 µV. The device draws 750 µA of supply current and delivers up to 50 mA of output current per channel. It is housed in a SOT-23-5 surface-mount package and functions within a temperature range of -40°C to +85°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix /250 against the manufacturer datasheet to confirm packaging configuration and reel quantity. Ensure the component meets RoHS compliance requirements for your region. Cross-reference the MSL rating for moisture sensitivity handling during assembly. Confirm that the SOT-23-5 footprint matches your PCB design constraints before finalizing procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a balance of moderate bandwidth and low power consumption is required. The rail-to-rail performance makes it suitable for single-supply applications where signal swing is critical. Consider the 150 µV offset voltage for precision tasks, but verify if lower noise or higher drive current is needed for specific load conditions compared to other family members.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the OPA340 family of micro-power, rail-to-rail operational amplifiers. It shares core architectural similarities with variants like the OPA340NA/3K and OPA340PA, differing primarily in packaging type and reel quantity. The family is designed for general-purpose analog signal processing in space-constrained, battery-operated environments.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct substitutes include OPA340NA/3K for identical electrical performance in different reel quantities. For through-hole applications, the OPA340PA offers the same functionality in a PDIP-8 package. Verify pinout compatibility and thermal characteristics when transitioning between these variants.
