Zero-crossover topology eliminates input stage crossover distortion common in RRIO amplifiers, providing 100dB CMRR and 0.0004% THD+N. 100uV offset, 0.2pA bias current, 4.5nV\/sqrtHz noise. 2.2-5.5V supply with output swinging within 10mV of rails.","working_principle":"Uses TI's zero-crossover distortion topology where the input pair is dynamically biased to maintain constant transconductance across the entire common-mode range. This eliminates the crossover region distortion that occurs in conventional RRIO amplifiers when the common-mode voltage transitions between the N-channel and P-channel input pairs. The result is seamless 100dB CMRR across the full input range. Rail-to-rail output uses a common-source output stage with adaptive biasing.","pin_description":"
