3.3V ELECTRICAL CHARACTERISTICS ⁽¹⁾ (continued)
Unless otherwise specified, all limits are specified for T_A= 25°C, V_{CM_REF} = 1.2V, both inputs tied to 0.3V through 50Ω(R_S1 &
R_S2) each ⁽²⁾, V_S = 3.3V, R_L = 100Ω differential, V_OUT = 0.8 V_PP. See DEFINITION OF TERMS AND SPECIFICATIONS
(ALPHABETICAL ORDER) for definition of terms used throughout the datasheet. Boldface limits apply at the temperature
extremes.

(8) Drift determined by dividing the change in parameter at temperature extremes by the total temperature change.
(9) Positive current is current flowing into the device.
(10) Total supply current is affected by the input voltages connected through R_S1 and R_S2. Supply current tested with input removed.
