See the Input Voltage Range section in the Theory of Operation 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 Figure 19 through Figure 22 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 24 and Figure 25 for details. 7 Power dissipation (PDISS) at quiescent condition is computed by multiplying the supply voltage and quiescent supply current (IQ). PDISS = VS × IQ, PDISS = 2.7 V × 200 µA, PDISS = 0.54 mW. Rev.
