1 Includes amplifier voltage and current noise, as well as noise of internal resistors.
2 Includes input bias and offset errors.
3 At voltages beyond the rails, internal ESD diodes begin to turn on. In some configurations, the input voltage range may be limited by the internal op amp (see the
section for details).
Input Voltage Range
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.
