(1) Electrostatic discharge (ESD) to measure device sensitivity and immunity to damage caused by assembly line electrostatic discharges in to the device.
(2) Level listed above is the passing level per ANSI, ESDA, and JEDEC JS-001. JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process.
(3) Level listed above is the passing level per EIA-JEDEC JESD22-C101. JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process.

(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) The maximum power dissipation is a function of TJ(MAX), θJA, and TA. The maximum allowable power dissipation at any ambient temperature is PD = (TJ(MAX) - TA)/ θJA . All numbers apply for packages soldered directly onto a PC board.
(3) The package thermal impedance is calculated in accordance with JESD 51-7.
(4) Electrical Characteristics Table values apply only for factory testing conditions at the temperature indicated. Factory testing conditions result in very limited self-heating of the device such that TJ = TA. Parametric performance shown in the electrical tables is not ensured under conditions of internal self-heating where TJ > TA.
(5) Electrical Characteristics apply only when SWIF is inactive. Glitches may appear on SWDRV during a SWIF transmission.
(6) Typical values represent the most likely parametric norm as determined at the time of characterization. Actual typical values may vary over time and will also depend on the application and configuration. The typical values are not tested and are not ensured on shipped production material.
(7) Limits are ensured by testing, design, or statistical analysis at 25°C. Limits over the operating temperature range are ensured through correlations using statistical quality control (SQC) method.
(8) There are tradeoffs between power consumption, switching speed, RP to Digital conversion and oscillation frequency.
(9) Supply current is higher when there is not an LC tank connected to Terminals INA and INB because an internal protection circuit is enabled. See the Supply Current vs Supply Voltage graphs in the
Typical Characteristics section.
(10) The loop supply must be able to momentarily supply 30mA.
