In some configurations, the input voltage range may be limited by the internal op amp (see the Input Voltage Range section for details). 4 Internal resistors are trimmed to be ratio matched but have ±20% absolute accuracy. Common-mode resistance was calculated with both inputs in parallel. Common- mode impedance at only one input is 2× the resistance listed. Rev.
