* These parameters are characterized but not tested. † Data in “Typ” column is at 3.0V, 25°C unless otherwise stated. These parameters are for design guidance only and are not tested. Note: Output swing depends on load. Internal resistor ladder consists of multiple unit resistors 'R'. Internal gain set to Noninverting (1 + R2/R1).
