NOTES
1
For best performance, bypass +5 V dc supplies to com. at or near the device (0.01
μ
F). +5 V dc supplies are also internally bypassed with 0.05
μ
F.
2
As the supply voltage is applied to either side of the AD260, the internal circuitry will go into a power-up reset mode (all lines disabled) for about 30
μ
s after the point where
+5 V dc
SYS & FLD
passes above 3.3 V.
3
“Operating” isolation voltage is derived from the Isolation Test Voltage in accordance with such methods as found in VDE-0883 wherein a device will be “hi-pot” tested at twice
the operating voltage, plus one thousand volts. Partial discharge testing, with an acceptance threshold of 80 pC of discharge may be considered the same as a hi-pot test (but
nondestructive).
4
Partial Discharge at 80 pC THLD.
5
Supply Current will increase slightly, but otherwise the unit will function within specification to –40
°
C.
Specifications are subject to change without notice.
