The Texas Instruments OPA365AIDBVR is a 50 MHz rail-to-rail CMOS operational amplifier from the zerø-crossover series. It combines 25 V/µs slew rate, 4.5 nV/√Hz noise and 100 µV typical offset with rail-to-rail input and output for single-supply designs. Supplied in a 5-pin SOT-23, it is optimised for driving sampling ADCs and precision signal conditioning.

FAQ
What does “zerø-crossover” mean for the OPA365AIDBVR?
Its input topology avoids the crossover distortion common to rail-to-rail CMOS amplifiers, achieving 0.0004% THD+N across the full common-mode range.
What is the supply range of the OPA365AIDBVR?
It operates from a single 2.2 V to 5.5 V supply with rail-to-rail input and output, ideal for low-voltage and battery-powered signal chains.
