LTC6911HMS-1#TRPBF

Instrumentation, Op Amps, Buffer Amps Overview

The LTC6911HMS-1#TRPBF is a dual matched digitally programmable gain amplifier in a 10-lead MSOP package. It features a 3-bit parallel interface for selecting inverting voltage gains of 0, 1, 2, 5, 10, 20, 50, and 100 V/V. The device operates on single or dual supplies ranging from 2.7V to 10.5V. Key electrical characteristics include an 11MHz gain-bandwidth product, 10nV/√Hz input noise density, and rail-to-rail output swing. The H-grade variant supports an operating temperature range of -40°C to +125°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm the H-grade designation matches the required extended temperature range specifications for your application environment. Ensure the digital interface logic levels are compatible with the host controller driving the G0, G1, and G2 pins.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select the LTC6911HMS-1#TRPBF over the -2 option when gains of 0, 1, 2, 5, 10, 20, 50, and 100 V/V are required. Consider the input resistance variations at higher gain settings when interfacing with high-impedance sources. Verify that the supply voltage range accommodates the required output swing and headroom for the specific application load.

Instrumentation, Op Amps, Buffer Amps Part Context

This component belongs to the LTC6911 family of low-noise digitally programmable gain amplifiers. The family includes variants with different gain steps (-1 and -2 options) and temperature grades (C, I, and H). The MSOP package provides a compact footprint suitable for space-constrained designs requiring precision analog signal processing.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

LTC6911IMS-1#TRPBF offers identical functionality with a commercial temperature range. LTC6911CMS-1#TRPBF is available for standard industrial applications. For non-inverting requirements or different gain sets, the LTC6912 series may be considered.
