LTC6259IMS8#PBF

Instrumentation, Op Amps, Buffer Amps Overview

The LTC6259IMS8#PBF is a dual operational amplifier featuring rail-to-rail input and output capabilities. It operates on supply voltages ranging from 1.8V to 5.25V with a quiescent current of 20µA per amplifier. The device offers a gain-bandwidth product of 1.3MHz, an input offset voltage maximum of 400µV, and an input bias current of 75nA maximum. It includes a shutdown pin that reduces current consumption to 7µA maximum. The component is housed in an 8-lead MSOP package and supports an operating temperature range from –40°C to 85°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix #PBF indicates RoHS and WEEE compliance status before finalizing procurement orders. Confirm the IMS8 designation corresponds to the 8-lead plastic MSOP package variant required for your PCB layout. Ensure the 'I' grade temperature range meets your environmental specifications. Cross-reference the manufacturer part number with official distributor catalogs to confirm availability and authenticity.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for applications requiring low power consumption combined with high bandwidth. The dual configuration is suitable for differential signal processing or stereo channels. Consider the shutdown feature if power management is critical. Verify that the 1.3MHz gain-bandwidth product meets your frequency requirements. Ensure the 20µA quiescent current aligns with your system's energy efficiency goals.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the LTC6258/LTC6259/LTC6260 family of power-efficient rail-to-rail I/O operational amplifiers. The family includes single, dual, and quad variants sharing similar electrical characteristics. The dual version provides two independent amplifiers in a compact package. These devices are designed as plug-in replacements for many commercially available op amps to improve performance and reduce power.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Consult the manufacturer documentation for direct pin-compatible substitutes within the same family. Verify that any replacement maintains the 1.8V to 5.25V supply voltage range. Ensure the alternative device supports the required capacitive load driving capability. Check that the shutdown functionality and current consumption levels meet your design constraints.

Instrumentation, Op Amps, Buffer Amps FAQ

Does the LTC6259 support unity gain stability with capacitive loads?

Yes, the LTC6259 is designed to be unity gain stable with or without capacitive loads, capable of driving up to 100nF directly.

How does the shutdown pin affect the amplifier's operation?

Driving the SHDN pin below 0.6V shuts down the amplifier, reducing the supply current to a maximum of 7µA. Leaving it unconnected keeps the amplifier enabled.

What is the input common mode voltage range?

The inputs can extend beyond the negative and positive power supplies, allowing for ground sensing and true zero output swing capabilities.
