3 Description

The OPA986 and OPA2986 (OPAx986) are 48V capable, low noise, high precision, rail-to-rail, CMOS operational amplifiers on Texas Instruments latest process technology.

The OPAx986 enables next generation platforms supporting a wider input and output dynamic range. These systems can benefit from improved signal integrity and accuracy. The combination of high input impedance, rail-to-rail inputs, low noise, and wide bandwidth make these devices an excellent choice for data acquisition systems that interface with a wide range of sensors. The Mux-Friendly technology of these op amps provide a robust input stage that can improve settling behavior in multiplexed applications.

The OPAx986 are available in industry standard packages and can provide a drop-in upgrade to existing legacy sockets. These op amps are also available in industry leading, tiny packages to fit a variety of space constrained applications.
