DESCRIPTION
The OPAx375 family includes single (OPA375), dual (OPA2375) and quad-channel (OPA2375) generalpurpose CMOS operation amplifiers (op amp) that provide an extremely low noise figure of 3.5 nV/√Hz, a low offset of 500 µV (maximum) and a wide bandwidth of 10 MHz. The low noise and wide bandwidth make the OPAx375 family attractive for a variety of precision applications that require a good balance between cost and performance.
