Notes

1. Hysteresis between the rise and fall voltage when pin STANDBY is controlled with low ohmic voltage source.

2. At lower VP the voltage at the STANDBY pin for on condition will be adjusted automatically to maintain an

on condition at low battery voltage (down to 8 V) when using one-pin operation.

3. The noise output is measured in a bandwidth of 20 Hz to 20 kHz.
