OPA244NA/3K1G4

Instrumentation, Op Amps, Buffer Amps Overview

The OPA244NA/3K1G4 is a single-channel operational amplifier from the MicroAmplifier series, manufactured by Texas Instruments. It features a gain-bandwidth product of 430 kHz and operates within a supply voltage range of +2.2V to +36V (single) or ±1.1V to ±18V (dual). The device draws 50 μA per channel quiescent current. Key electrical parameters include an input offset voltage of ±1.5 mV, input bias current of -25 nA, and open-loop gain of 106 dB. It utilizes SOT-23-5 packaging.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix /3K1G4 against the manufacturer's latest Package Option Addendum to confirm active production status and RoHS compliance. Ensure the SOT-23-5 package type matches the intended PCB footprint. Confirm moisture sensitivity level ratings prior to assembly planning.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for designs requiring low power consumption alongside moderate bandwidth. The wide supply range allows flexibility in system architecture. Verify that the input common-mode voltage range includes ground if single-supply grounding is required. Check thermal resistance specifications for the SOT-23-5 package under expected load conditions.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the OPA244 family, which includes dual (OPA2244) and quad (OPA4244) variants. All versions share similar performance characteristics but differ in channel count and package options. The OPA244NA specifically denotes the single-channel version in the SOT-23-5 surface-mount package.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct functional replacements within the same family include OPA2244 and OPA4244, provided pin compatibility and channel requirements are met. Other packages such as SOIC-8 (OPA244UA) offer identical electrical performance with different physical dimensions.
