1 Includes input bias and offset current errors, RTO (referred to output).
2 The input voltage range may also be limited by absolute maximum input voltage or by the output swing. See the
section for details.
3 Internal resistors are trimmed to be ratio matched and have ±20% absolute accuracy.
4 Output voltage swing varies with supply voltage and temperature. See Figur
for details.
5 Includes amplifier voltage and current noise, as well as noise from internal resistors.
6 Supply current varies with supply voltage and temperature. See Figure
for details.
