Notes
1. Long time stability of COMIN switch point VSP and voltage trip point VTRIP: within 10 years of continuous operation
at VDD(max) and an average operating temperature of 55 °C the drift of VSP will not exceed ±10 mV. The maximum
drift for VTRIP will not exceed (±VTRIP(typ)/VSP(typ)) 10 mV.
2. Values given per degree Kelvin; tested on a sample basis.
3. Conformance to these specifications is only guaranteed if the slew rate of VDD is less than 25 V/ms.
