If the application calls for the input to sink current there will be approximately an additional 1 mV of output offset voltage for each 3 mA of current. Sink current should be limited to 100 mA max to avoid choke burnout. For higher supply voltages, up to ±15 volts, the positive supply pin must include a series current limiting resistor, Rs = (Vs – 5) / 0.01 (e.g., Vs = +15v, Rs = 1.0K Ω). Average power –13 dBm. detection is obtained at power levels below approximately For best pulse response the supply pins should be bypassed with an additional 1.0 µF capacitor. The unit contains 0.01 µF internal capacitors.
