OPA2340UA/2K5

Instrumentation, Op Amps, Buffer Amps Overview

The OPA2340UA/2K5 is a dual-channel precision CMOS operational amplifier optimized for low-voltage single-supply operation. It features rail-to-rail input and output capabilities, making it suitable for driving analog-to-digital converters. The device operates on a supply voltage range of 2.5 V to 5.5 V with a typical quiescent current of 750 µA per channel. Key electrical specifications include a gain-bandwidth product of 5.5 MHz, a slew rate of 6 V/µs, an input offset voltage of 0.5 mV, and an input bias current of 10 pA. It provides high dynamic response while maintaining low power consumption.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix /2K5 indicates tape-and-reel packaging when ordering. Confirm the SOIC-8 package dimensions match your PCB footprint requirements. Ensure the operating temperature range of -40°C to +85°C aligns with your system environment. Check for RoHS compliance status if required by your manufacturing standards. Validate that the humidity sensitivity level meets your assembly process constraints.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when both precision and speed are required in a low-power single-supply environment. The rail-to-rail I/O eliminates the need for negative supplies or complex biasing networks. Consider the 5.5 MHz bandwidth for applications requiring faster settling times than standard micropower amplifiers offer. The low input bias current makes it suitable for high-impedance sensor interfaces.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to Texas Instruments' MicroAmplifier series, designed for battery-powered and portable devices. The OPA2340 variant specifically offers precision characteristics compared to other members like the OPA2343 which prioritizes wider bandwidth over lower offset. The family includes single, dual, and quad versions sharing similar electrical specifications to simplify multi-channel designs.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

OPA2340UA (tray packaging) serves as a functional equivalent with identical electrical characteristics but different shipping format. OPA2340EA/2K5 offers the same performance in an 8-VSSOP package for space-constrained layouts. Verify pin compatibility and thermal requirements when substituting packages within the same series.
