LTC6247CMS8#TRPBF

Instrumentation, Op Amps, Buffer Amps Overview

The LTC6247CMS8#TRPBF is a dual-channel, low-power, high-speed operational amplifier featuring unity gain stability and rail-to-rail input/output capabilities. It operates within a supply voltage range of 2.5V to 5.25V with a typical quiescent current of 1mA per amplifier. Key electrical specifications include a 180MHz gain-bandwidth product, a 90V/µs slew rate, and an input-referred noise density of 4.2nV/√Hz at 100kHz. The device includes a shutdown pin that reduces current consumption to 42µA when disabled.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging configuration. Confirm the 'C' grade designation aligns with the required commercial operating temperature range of 0°C to 70°C. Ensure the MSOP-8 package type matches the target PCB footprint requirements. Cross-reference the manufacturer part number against official Analog Devices documentation to validate authenticity and revision status.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for applications requiring high bandwidth and low power consumption simultaneously. The dual-channel configuration is suitable for differential signal processing or stereo buffering. Verify that the 1mA supply current meets system power budgets. Consider the shutdown feature if power management during idle states is necessary. Ensure the load conditions do not exceed the specified output current limits.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the LTC6246/LTC6247/LTC6248 family of power-efficient rail-to-rail I/O op amps. The LTC6247 specifically denotes the dual-channel variant, whereas the LTC6246 is single-channel and the LTC6248 is quad-channel. All variants share identical electrical characteristics and pinouts relative to their channel count.
