b. See the Definitions section.

c. Gain temperature drift can be normalized and expressed as Temperature Coefficient of Gain (TCG) of –50 ppm/°C.

d. When FSR is exceeded, outputs saturate.

All Typical values are under Typical Operating Conditions at T_A= 25°C, V_DD1= 5 V, V_DD2= ±.± V.

Because of the switched-capacitor nature of the input sigma-delta converter, time-averaged values are shown.

Under Typical Operating Conditions, part-to-part variation ±0.04 V.

g. Under Typical Operating Conditions, part-to-part variation ±1 dB.

h. Under Typical Operating Conditions, part-to-part variation ±1 dB.

Ripple voltage applied to V_DD1with a 0.1 μF bypass capacitor connected; differential amplitude of the ripple outputs measured. See Definitions section.

The input supply current decreases as the differential input voltage (V_IN+– V_IN–) decreases.

In accordance with UL 1577, each optocoupler is proof tested by applying an insulation test voltage ≥ 9000Vrms for 1 second (leakage detection current limit,

_I-O≤ 5μ A). This test is performed before the 100% production test for partial discharge (method b) shown in IEC/EN/DIN EN 60747-5-5 Insulation

Characteristic Table.

b. The Input-Output Momentary Withstand Voltage is a dielectric voltage rating that should not be interpreted as an input-output continuous voltage rating.

For the continuous voltage rating, refer to the IEC/EN/DIN EN 60747-5-5 insulation characteristics table and your equipment level safety specification.

This is a two-terminal measurement: pins 1–4 are shorted together and pins 5–8 are shorted together.
