OPA820IDBVR

Instrumentation, Op Amps, Buffer Amps Overview

The OPA820IDBVR is a high-speed, unity-gain stable voltage feedback operational amplifier manufactured by Texas Instruments. It features a gain-bandwidth product of 260 MHz and a slew rate of 200 V/µs. The device operates on a single supply voltage ranging from 5 V to 12 V or dual supplies of ±2.5 V to ±6 V. Key electrical specifications include an input bias current of ±400 nA, an input offset voltage of ±750 µV, and an output current capability of 110 mA. It is housed in an 8-pin SOIC surface-mount package with an operating temperature range of -40°C to 85°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the complete part number including the suffix 'DBVR' to confirm the specific tape-and-reel packaging variant. Confirm that the required operating temperature range aligns with the industrial specification limits. Ensure compatibility with the target PCB footprint for the 8-pin SOIC package. Cross-reference the manufacturer's latest datasheet for any updates regarding pin configuration or recommended operating conditions before finalizing procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a unity-gain stable, high-speed amplifier is required for video or broadband applications. The 260 MHz gain-bandwidth product and 200 V/µs slew rate distinguish it from lower-speed general-purpose amplifiers. Consider the 110 mA output drive capability for driving low-impedance loads. Evaluate the power supply requirements against the 5 V to 12 V single-supply constraint. Compare noise performance against other high-speed op-amps if signal integrity is critical.

Instrumentation, Op Amps, Buffer Amps Part Context

The OPA820IDBVR belongs to the OPA820 series of high-speed operational amplifiers from Texas Instruments. This series is designed for applications requiring fast transient response and wide bandwidth. The 'I' designation indicates the industrial temperature grade, while 'D' specifies the SOIC package type. The 'BVR' suffix denotes the specific reel-based packaging format used for automated assembly processes.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Consult the official Texas Instruments substitution guide for verified alternatives. Direct replacements must match the 8-pin SOIC package and unity-gain stability. Verify that substitute parts meet or exceed the 260 MHz gain-bandwidth product and 200 V/µs slew rate specifications. Ensure thermal and electrical compatibility within the 5 V to 12 V supply range.
