OPA2340EA/250G4

Instrumentation, Op Amps, Buffer Amps Overview

The OPA2340EA/250G4 is a dual-channel, low-offset voltage operational amplifier from Texas Instruments' MicroAmplifier series. It features rail-to-rail input and output capabilities, supporting single-supply operation between 2.5 V and 5.5 V. Key electrical parameters include a gain-bandwidth product of 5.5 MHz, a slew rate of 6 V/µs, and an input bias current as low as 10 pA. The device operates within a temperature range of -40°C to +85°C and is housed in an 8-VSSOP package.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Rail-to-rail input and output functionality for maximum dynamic range in single-supply applications.
• Low offset voltage specification ensures high precision in signal conditioning circuits.
• CMOS architecture provides low power consumption with a typical supply current of 750 µA.

Instrumentation, Op Amps, Buffer Amps Applications

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the suffix G4 indicates RoHS compliance and lead-free construction per manufacturer standards. Confirm the EA/250 designation corresponds to the specific 8-VSSOP package variant and commercial temperature grade. Ensure compatibility with existing PCB footprints before integration.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when both rail-to-rail performance and low offset voltage are required in a compact surface-mount package. Compare against the OPA2340UA variant if SOIC packaging is preferred. Consider the OPA2340NA for single-channel requirements or the OPA4340 for quad-channel configurations.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the OPA2340 family of micro-power, precision amplifiers. It shares core electrical characteristics with other variants like the OPA2340UA and OPA2340PA, differing primarily in package type and pinout configuration. The family is designed for general-purpose precision applications requiring low power and high accuracy.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct pin-compatible alternatives include the OPA2340UA/2K5 (SOIC-8) and OPA2340PA (DIP-8). Verify that the substitute maintains the same rail-to-rail input/output specifications and offset voltage limits to ensure circuit performance parity.
