OPA2340UAG4

Instrumentation, Op Amps, Buffer Amps Overview

The OPA2340UAG4 is a dual-channel, precision CMOS operational amplifier from Texas Instruments' microPOWER 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 a maximum input offset voltage of 150 µV. The device draws a typical quiescent current of 750 µA for both channels. It is housed in an 8-pin SOIC package with lead-free (G4) termination.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Rail-to-rail input and output performance optimized for low-voltage single-supply operation
• Precision characteristics including low input offset voltage and low bias current
• High-speed operation with 5.5 MHz gain-bandwidth product and 6 V/µs slew rate
• Low power consumption with 750 µA total supply current for the dual-channel design

Instrumentation, Op Amps, Buffer Amps Applications

• Driving analog-to-digital converters (ADCs)
• General-purpose signal conditioning circuits
• Audio applications requiring high fidelity
• Current-to-voltage conversion at digital-to-analog converter (DAC) outputs

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the G4 suffix indicates lead-free compliance and RoHS 3 standards. Confirm the SOIC-8 package dimensions match the target PCB footprint. Ensure the operating temperature range of -40°C to +85°C aligns with system requirements. Check moisture sensitivity level (MSL 2) handling procedures if storage conditions exceed limits.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a dual-channel amplifier with rail-to-rail I/O is required under a 5.5 V maximum supply. The 750 µA current draw suits battery-powered designs. The 5.5 MHz bandwidth supports moderate-speed signal processing. Compare against OPA2340 variants with different packaging or channel counts if pinout flexibility is needed.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the OPA2340 family of microPOWER op amps, which includes dual (OPA2340), quad (OPA4340), and single (OPA1340) channel versions. All variants share identical electrical specifications to simplify multi-channel design scaling. The OPA2340UAG4 specifically denotes the dual-channel version in an 8-SOIC package with green (lead-free) terminations.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct functional equivalents within the same family include OPA2340UA (standard leaded SOIC-8). For lead-free alternatives in different packages, consider OPA2340EA/250 (VSSOP-8). Verify that substitute parts maintain the 5.5 MHz bandwidth and 750 µA current consumption constraints.
