Notes to the characteristics
1. Hysteresis between rise and fall voltage when MSB pin is controlled with real voltage source (the hysteresis depends
on resistor connected to MSB pin).
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.
