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