LTC1841/LTC1842/LTC1843
PIN FUNCTIONS
OUT A (Pin 1): Comparator A Open-Drain Output. Output
can typically sink greater than 20mA.
V – (Pin 2): Negative Supply.
IN A+ (Pin 3): Noninverting Input of Comparator A. Input
common mode range extends from V – to V + – 1.3V. Input
current is typically 10pA at 25°C.
IN A – (Pin 4) (LTC1841): Inverting Input of Comparator A.
Input common mode range extends from V – to V + – 1.3V.
Input current is typically 10pA at 25°C.
IN B+ (Pin 4) (LTC1842): Noninverting Input of Compara-
tor B. Input common mode range extends from V – to
V + – 1.3V. Input current is typically 10pA at 25°C.
IN B– (Pin 4) (LTC1843): Inverting Input of Comparator B.
Input common mode range extends from V – to V + – 1.3V.
Input current is typically 10pA at 25°C.
IN B– (Pin 5) (LTC1841): Inverting Input of Comparator B.
Input common mode range extends from V – to V + – 1.3V.
Input current is typically 10pA at 25°C.
HYST (Pin 5) (LTC1842/LTC1843): Hysteresis Input.
Connect to REF if not used. Input voltage range is from
VREF to VREF – 50mV.
IN B + (Pin 6) (LTC1841): Noninverting Input of Compara-
tor B. Input common mode range extends from V – to
V + – 1.3V. Input current is typically 10pA at 25°C.
REF (Pin 6) (LTC1842/LTC1843): Reference Output.
1.182V with respect to V –. Can typically source greater
than 1mA and sink 10µA at 25°C. Can drive 0.01µF bypass
capacitor without oscillation.
V + (Pin 7) (LTC1841): Positive Supply. 2V to 11V.
V + (Pin 7) (LTC1842/LTC1843): Positive Supply. 2.5V to
11V.
OUT B (Pin 8): Comparator B Open-Drain Output. Output
can typically sink greater than 20mA.
