ISC300

SPECIFICATIONS (CONT)

ELECTRICAL

At VCC = 15V, VDD = 5V, TA = +25°C, unless otherwise noted.

NOTES: (1) See “High Voltage Testing” Section. (2) IMR is defined with respect to the voltage between Com 1 and Com 2 with both inputs tied to Com 1. (3) CMR is

defined with respect to the input common, Com 1, only. (4) Deviation from a straight line between the end points of the output voltage. (5) Device output remains

monotonic. (6) Limit referred to VREF1.
