OPA2392YBJT

Instrumentation, Op Amps, Buffer Amps Overview

The OPA2392YBJT is a dual-channel precision operational amplifier from the OPAx392 family, utilizing e-trim technology for ultra-low offset voltage and drift. It features rail-to-rail input and output capabilities with a gain-bandwidth product of 13 MHz and a slew rate of 4.5 V/µs. The device operates on supply voltages ranging from 1.7 V to 5.5 V, drawing a quiescent current of 1.22 mA per amplifier. Key electrical specifications include an input bias current of 10 fA, input voltage noise density of 4.4 nV/√Hz at 10 kHz, and short-circuit protection providing +65 mA sourcing and -55 mA sinking currents.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Analog input modules and process analytics

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify that the specific YBJ ordering suffix corresponds to the DSBGA package variant containing the Enable pin functionality. Confirm that the component matches the production data status rather than preview information. Ensure compatibility with the specified operating temperature range and supply voltage requirements before integration into the final design.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when both dual-channel configuration and ultra-low DC precision are required. The YBJ package offers a compact footprint but includes an enable pin not present in other package variants like DGK or D. Consider the 1.22 mA quiescent current if power efficiency is critical compared to lower-power alternatives. Verify thermal dissipation requirements for the DSBGA package in dense layouts.

Instrumentation, Op Amps, Buffer Amps Part Context

The OPA2392YBJT belongs to the OPAx392 family, which also includes the single-channel OPA392 and quad-channel OPA4392. All variants share the same core e-trim architecture and electrical characteristics. The YBJ suffix specifically denotes the dual-channel version housed in a 9-pin DSBGA package, distinguishing it from SOIC or VSSOP options.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct functional replacements within the same family include OPA392YBJ for single-channel needs and OPA4392RTE for quad-channel configurations. Other package variants such as OPA2392DGK or OPA2392D offer identical electrical performance but differ in physical footprint and pinout.
