... Application hint 6.1 Input signal dynamic range The STG5678 negative analog switch allows input signals that fall below pass through the switch without signal distortion. The input signal dynamic range VI consists of a positive-region and a negative-region. The positive-region is limited by the level of V difference between V the operating range in the negative region ...
