LTC6911IMS-2#PBF

Instrumentation, Op Amps, Buffer Amps Overview

The LTC6911IMS-2#PBF is a dual matched amplifier with digitally programmable gain in a 10-lead MSOP package. It features a 3-bit parallel interface for inverting gains of 0, 1, 2, 4, 8, 16, 32, and 64 V/V. The device operates on single or dual supplies from 2.7V to 10.5V total. Key electrical parameters include an 11MHz gain-bandwidth product, 10nV/√Hz input noise density, and 0.1dB maximum channel-to-channel gain matching. It provides rail-to-rail input and output swing capabilities.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and tube packaging when sourcing. Confirm the IMS-2 designation matches the required power grade and gain step configuration (0, 1, 2, 4, 8, 16, 32, 64 V/V). Ensure the 10-lead MSOP footprint aligns with the target PCB layout constraints before finalizing procurement orders.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when precise digital gain control is required for dual-channel signal conditioning. The -2 option specifically provides binary-weighted gain steps suitable for wide dynamic range applications. Consider the input resistance variations at higher gain settings when interfacing with source impedances to minimize gain errors.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the LTC6911 family of low-noise programmable gain amplifiers. The IMS-2 variant specifies the industrial temperature range (-40°C to 85°C) and the specific binary gain ladder. It serves as a compact solution for replacing discrete resistor networks in precision analog front ends.
