Electrical Specifications (Tested with HCPL-0872 or Sinc3 Filter)
Unless otherwise noted, all specifications are at VIN+ = -200 mV to +200 mV and VIN- = 0 V; all Typical specifications are
at TA = 25°C and VDD1 = VDD2 = 5 V, and all Minimum and Maximum specifications apply over the following ranges: TA = -
40°C to +85°C, VDD1 = 4.5 to 5.5 V and VDD2 = 4.5 to 5.5 V.
