Dual op-amp for general-purpose signal conditioning
The Analog Devices LT1112IS8#TRPBF is a dual general-purpose operational amplifier in an 8-SOIC package. It combines a 750 kHz gain-bandwidth product with a 25 µV maximum input offset voltage and a supply current of 350 µA per channel, making it a fit for precision low-level signal amplification in industrial and portable systems. The 2 V to 40 V supply span lets it work from a single lithium cell to a 24 V industrial rail.
Supply voltage range: 2 V to 40 V — one part covers low-voltage portable and industrial rails
The 2 V minimum supply span lets the LT1112 run from a single Li-ion cell or a 3.3 V regulated rail without a boost converter. At the other end, the 40 V maximum covers 24 V industrial buses with headroom for transients. This wide range simplifies inventory — one op-amp type for both battery-powered and line-powered boards.
Temperature grade: industrial range for outdoor and factory environments
Rated for -40°C to 85°C, the LT1112IS8#TRPBF suits outdoor telecom cabinets, factory-floor sensor interfaces, and engine-bay electronics where the ambient can swing below freezing. The 25 µV offset holds across the temperature range — no need to re-trim the null circuit when the board heats up.
Package and footprint: 8-SOIC with standard 0.154" width
The 8-SOIC (0.154" body width, 3.90 mm) with supplier device package 8-SO is a widely used footprint shared by many dual op-amps. This simplifies PCB layout and opens up second-source options without a board spin.
Lifecycle and sourcing: active, no obsolescence risk
The LT1112IS8#TRPBF carries an active lifecycle status with ROHS3 compliance.
