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 Input Voltage Range 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 Figure 22 through Figure 25 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 26 and Figure 28 for details.
7 Unbalanced dual supplies can be used, such as −VS = −0.5 V and +VS = +2 V. The positive supply rail must be at least 2 V above the negative supply and reference
voltage.
