Data Sheet Isolation Amplifer
Insulation and Safety-Related Specifications Parameter Symbol Value Units Conditions
Minimum External Air Gap L(101) 7.4 mm Measured from input terminals to output terminals, (Clearance) shortest distance through air. Minimum External Tracking L(102) 8.0 mm Measured from input terminals to output terminals, (Creepage) shortest distance path along the body. Minimum Internal Plastic Gap 0.5 mm Through insulation distance conductor to conductor, (Internal Clearance) usually the straight line distance thickness between the emitter and the detector. Tracking Resistance CTI >175 V DIN IEC 112/VDE 0303 Part 1 (Comparative Tracking Index) Isolation Group III a Material Group (DIN VDE 0110, 1/89, Table 1)

Ambient Operating Temperature TA –40 85 °C Supply Voltage VDD1, VDD2 4.5 5.5 V Input Voltage (accurate and linear) VIN+, VIN– –200 200 mV a Input Voltage (functional) VIN+, VIN– –2 2 V a. Broadcom recommends operation with VIN– = 0V (tied to GND1). Limiting VIN+ to 100 mV improves DC nonlinearity and nonlinearity drift. If VIN– is brought above VDD1 – 2V, an internal test mode may be activated. This test mode is for testing LED coupling and is not intended for customer use.
NOTE:
For the following tables, Typical values represent the mean value of all characterization units at the nominal operating conditions. Typical drift specifications are determined by calculating the rate of change of the specified parameter versus the drift parameter (at nominal operating conditions) for each characterization unit, and then averaging the individual unit rates. The corresponding drift figures are normalized to the nominal operating conditions and show how much drift occurs as the particular drift parameter is varied from its nominal value, with all other parameters held at their nominal operating values. Note that the typical drift specifications in the following tables may differ from the slopes of the mean curves shown in the corresponding figures.
