Connect to V – for single supply operation. V – (Pin 2): Negative Supply. Connect to ground for single supply operation. Potential should be more negative than GND. IN + (Pin 3): Noninverting Comparator Input. Input com- mon mode range from V – to V + –1.3V. Input current typically 10pA at 25 °C. IN – (Pin 4): Inverting Comparator Input. Input common mode range from V – to V + –1.3V. Input current typically 10pA at 25 °C. HYST (Pin 5): Hysteresis Input. Connect to REF if not used. Input voltage range is from VREF to VREF – 50mV. REF (Pin 6): Reference Output. 1.182V with respect to V –. Can source up to 200 µA and sink 15µA at 25°C. Drive 0.01 µF bypass capacitor without oscillation. V + (Pin 7): Positive Supply. 2V to 11V. OUT (Pin 8): Comparator CMOS Output. Swings from GND to V +. Output can source up to 40mA and sink 5mA. LTC1441 OUT A (Pin 1): Comparator A CMOS Output. Swings from V – to V +. Output can source up to 40mA and sink 5mA. V – (Pin 2): Negative Supply. IN A+ (Pin 3): Noninverting Input of Comparator A. Input common mode range from V – to V + –1.3V.
