AN855 Datasheet, PDF (2/3 Pages) Silicon Laboratories – ADJUSTING HYSTERESIS ON A DUAL COMPARATOR USING ONE RESISTOR

AN855
The new feedback network consisting of R2 as 1 M and R1 as 17.2 k, the resulting hysteresis band is equal to
40 mV with an upper threshold occurring at 1.202 V and a low threshold occurring at 1.202 V.
As shown in this application note, the hysteresis band for Silicon Labs’ TS9002 low-power dual comparator can be
easily adjusted by only changing the value of one resistor within the feedback network.
