Electrical Specifications (Tested with HCPL-0872 or Sinc
3
Filter)
Unless otherwise noted, all specifications are at V
IN+
= -200 mV to +200 mV and V
IN-
= 0 V; all Typical specifications are
at T
A
= 25°C and V
DD1
= V
DD2
= 5 V, and all Minimum and Maximum specifications apply over the following ranges: T
A
= -
40°C to +85°C, V
DD1
= 4.5 to 5.5 V and V
DD2
= 4.5 to 5.5 V.
