This is a stress rating only and functional operation of the device at those or any other conditions above those indicated in the operational listings of this specification is not implied. Expo- sure to maximum rating conditions for extended periods may affect device reliability. DC CHARACTERISTICS Electrical Characteristics: Unless otherwise indicated: V DD = +1.8V to +5.5V, VSS = GND, TA = +25°C, VIN+ = VDD/2, VIN- = VSS, Parameters Symbol Min Typ Max Units Conditions Power Supply Supply Voltage VDD 1.8 — 5.5 V Quiescent Current per comparator IQ 60 100 130 µA IOUT = 0 Power Supply Rejection Ratio PSRR 63 70 — dB VCM = VSS Input Input Offset Voltage VOS -10 ±3+10 mV Input Offset Drift ΔV OS/ΔT— ±2— µV/°C VCM = VSS Input Offset Current IOS — ±1— pA VCM = VSS Input Bias Current IB —1 — pA TA = +25°C, VIN- = VDD/2 —60 — pA TA = +85°C, VIN- = VDD/2 — 1500 5000 pA TA = +125°C, VIN- = VDD/2 Input Hysteresis Voltage VHYST 1.0 — 5.0 mV Input Hysteresis Linear Temp.

The input hysteresis is the difference between the input-referred trip points. 2: VHYST at different temperatures is estimated using VHYST (TA) = VHYST @ +25°C + (TA - 25°C) TC1 + (TA - 25°C) 2 TC 2. 3: Limit the output current to Absolute Maximum Rating of 50 mA. 4: The pull up voltage for the open drain output VPULL_UP can be as high as the absolute maximum rating of 10.5V.
