OPA310IDBVR

Instrumentation, Op Amps, Buffer Amps Overview

The OPA310IDBVR is a single-channel operational amplifier from the Texas Instruments OPAx310 family, housed in a 5-pin SOT-23 package. It operates on a supply voltage ranging from 1.5V to 5.5V and features rail-to-rail input and output capabilities. Key electrical specifications include a gain-bandwidth product of 3MHz, a slew rate of 3V/µs, and an input offset voltage of ±250µV typical. The device delivers high output current with a typical short-circuit current of ±150mA at 5.5V and maintains a low quiescent current of 165µA per channel.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• High output current capability with internal current limit and thermal shutdown protection for robust operation under heavy loads.
• Rail-to-rail input and output swing allows signal processing close to power supply rails across the full operating temperature range.
• Integrated RFI and EMI rejection filter provides noise immunity without phase reversal during input overdrive conditions.
• Fail-safe input structure eliminates diodes between inputs and the positive supply rail, enhancing system reliability.

Instrumentation, Op Amps, Buffer Amps Applications

• Optical modules
• Reference buffers and guard amplifiers
• Microphone pre-amplifiers
• Lighting and LED drivers
• 4-20mA loop drivers

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix 'DBVR' corresponds to the SOT-23-5 package configuration required for your design. Confirm that the component meets all RoHS compliance standards applicable to your region. Ensure that the supply chain source provides valid traceability documentation consistent with Texas Instruments manufacturing protocols.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a single-channel amplifier requires high drive strength combined with low power consumption. The OPA310IDBVR is suitable for applications needing rail-to-rail performance within a compact footprint. Consider the OPA310S variant if active shutdown functionality is necessary for duty-cycled signal chains.

Instrumentation, Op Amps, Buffer Amps Part Context

This device belongs to the OPAx310 series, which includes dual (OPA2310) and quad (OPA4310) channel variants. All members share similar electrical characteristics, including the 3MHz bandwidth and high output current profile. The OPA310IDBVR specifically represents the single-channel version optimized for space-constrained designs requiring independent control.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct pin-compatible substitutes within the same family include the OPA310IDCKR (SC70-5 package). For designs requiring shutdown control, the OPA310S series offers equivalent performance with added enable/disable functionality.
