It achieves 100 dB minimum CMRR with no input stage crossover distortion, a critical advantage over traditional CMOS op amps that exhibit CMRR degradation near the supply rails. The 100 uV maximum offset voltage, 1 uV\/C drift, and 4.5 nV\/sqrt(Hz) noise make it ideal for precision signal conditioning. The output swings within 10 mV of both rails, maximizing dynamic range in single-supply applications from 2.2V to 5.5V.","working_principle":"The OPA2365AIDR uses TI proprietary zero-crossover input stage topology. Traditional rail-to-rail CMOS op amps use two complementary differential pairs (PMOS and NMOS) that alternate as the common-mode voltage traverses the input range, causing CMRR degradation at the crossover point. The OPA2365 eliminates this by using a single differential pair with a charge-pump-boosted supply that keeps the input pair biased in its optimal region across the entire common-mode range. This results in 100 dB minimum CMRR with zero crossover distortion and 0.0004% THD+N. The output stage uses a class AB CMOS push-pull topology that swings to within 10 mV of each rail under light loads. Internal compensation ensures stability with capacitive loads up to 1 nF.","pin_description":"
