NOTES: (1) Ratings in parenthesis are between P- (pin 20) and O/P Com (pin 17). Other isolation ratings are between I/P Com and O/P Com or I/P Com and P–.
(2) See Performance Curves. (3) May be trimmed to zero. (4) If output swing is unipolar, or if the output is not loaded, specification same as if external supply were used.
(5) Includes effects of A
1
and A
2
offset voltages and bias currents if recommended resistors used. (6) Versus the sum of all external currents drawn from V+, V–, +V,
–V (= ISO). (7) Effects of A

bias currents and offset currents are included in Offset Voltage specifications. (8) With respect to I/P Com (pin 3) for A

and with
respect to O/P Com (pin 17) for A

. CMR for A
1
and A
2
is 100dB, typical. (9) In configuration of Figure 3. Ripple frequency approximately 750kHz. Measurement bandwidth
is 30kHz. (10) Decreases linearly from 16VDC at 85°C to 12VDC at 100°C. (11) Instantaneous peak current required from pins 19 and 20 at turn-on is 100mA for slow
rising voltages (50ms) and 300mA for fast rises (50µs). (12) Load current is sum drawn form +V, –V, V+, V– (= I
ISO
). (13) Maximum voltage rating at pins 1 and 4 is
±18VDC;
maximum voltage rating at pins 12 and 16 is
±18VDC.
(14) Isolation ratings may degrade if exposed to 125°C for more than 1000 hours or 90°C for more than 50,000
hours.
