LTC6255CDC#TRMPBF

Instrumentation, Op Amps, Buffer Amps Overview

The LTC6255CDC#TRMPBF is a single operational amplifier from Analog Devices, featuring rail-to-rail input and output capabilities. It operates on supply voltages ranging from 1.8V to 5.25V with a typical quiescent current of 65µA per amplifier. The device offers a gain-bandwidth product of 6.5MHz and a slew rate of 1.8V/µs. Key electrical specifications include a maximum input offset voltage of 350µV, a maximum input bias current of 50nA, and common mode rejection and power supply rejection ratios of 100dB. It is housed in a 6-lead (2mm × 2mm × 0.8mm) plastic DFN package.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Rail-to-rail input and output stages enable full signal swing across the supply range.
• C-Load technology ensures unity gain stability when driving large capacitive loads up to 100nF.
• Low noise performance with an input voltage noise density of 20nV/√Hz at 1kHz.
• Integrated shutdown function reduces supply current to less than 7µA for power conservation.

Instrumentation, Op Amps, Buffer Amps Applications

• Micropower active filters
• Portable instrumentation systems
• Battery or solar powered devices
• Automotive electronics

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix #TRMPBF indicates tape and reel packaging with mini-reel quantities. Confirm the CDC designation corresponds to the commercial temperature range of 0°C to 70°C. Ensure the lead-free finish matches project requirements. Cross-reference the manufacturer part number with official Analog Devices documentation to validate authenticity and revision status before procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for applications requiring low power consumption alongside high bandwidth. The rail-to-rail I/O capability makes it suitable for single-supply systems operating at low voltages like 1.8V. Consider the shutdown feature if power management is critical. Verify that the 65µA quiescent current meets system budget constraints compared to higher-performance but more power-hungry alternatives.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the LTC6255/LTC6256/LTC6257 family of micropower, low distortion op amps. While the LTC6255 is a single channel, the family includes dual and quad variants. The CDC suffix specifically denotes the commercial grade version in a 6-lead DFN package, distinct from industrial or automotive grades which may offer wider temperature ranges.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Consult official Analog Devices documentation for verified pin-compatible substitutes within the same family. Ensure any replacement maintains the 6.5MHz gain-bandwidth product and 65µA supply current characteristics. Verify that the alternative package matches the 6-lead DFN footprint and thermal requirements.

Instrumentation, Op Amps, Buffer Amps FAQ

Does the LTC6255CDC support driving capacitive loads?

Yes, the device features C-Load technology, allowing it to drive capacitive loads up to 100nF while maintaining unity gain stability.

What is the input voltage range of the LTC6255CDC?

The inputs are rail-to-rail, extending from V– – 0.1V to V+ + 0.1V, allowing for ground sensing and operation beyond the supply rails.

How does the shutdown pin affect operation?

Driving the SHDN pin below 0.6V above the negative rail shuts down the amplifier, reducing supply current to a maximum of 7µA and placing the output in a high-impedance state.
