Note 2: âAbsolute Maximum Ratingsâ are those values beyond which the safety of the device cannot be guaranteed. They are not meant to imply that the devices
should be operated at these limits. The tables of âElectrical Characteristicsâ provide conditions for actual device operation.
Note 3: Unless otherwise specified Min/Max limits apply across the â55ËC to +125ËC temperature range for DS9637AM and across the 0ËC to +70ËC range for the
DS9637ASC. All typicals are given for VCC = 5V and TA = 25ËC.
Note 4: All currents into the device pins are positive; all currents out of the device pins are negative. All voltages are referenced to ground unless otherwise specified.
Note 5: Only one output at a time should be shorted.
Note 6: VDIFF (Differential Input Voltage) = (VI+) â (VIâ). VCM (Common Mode Input Voltage) = VI+ or VIâ.
Note 7: 500⦠±1% in series with inputs.
Note 8: The input not under test is tied to ground.
