APPLICATION NOTES
This unit is DC coupled and employs a RF choke at the input (DC short). 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

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.
