(1) Typical values represent most likely parametric norms at T_A = +25ºC, and at the Recommended Operation Conditions at the time of
product characterization and are not ensured.
(2) Datasheet min/max specification limits are specified by test or statistical analysis.
(3) This is the distortion of the LME49610 operating in a closed loop configuration with an LME49710. When operating in an operational
amplifier's feedback loop, the amplifier's open loop gain dominates, linearizing the system and determining the overall system distortion.
