Analog Devices · Comparators · SO-8

LT1720IS8#PBF from Analog Devices, in a SO-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 +IN A input Noninverting input of comparator A; the common-mode input range is 100mV below ground to 1.2V below VCC.
2 -IN A input Inverting input of comparator A.
3 -IN B input Inverting input of comparator B.
4 +IN B input Noninverting input of comparator B; the common-mode input range is 100mV below ground to 1.2V below VCC.
5 GND power_in Ground reference for the device.
6 OUT B output Output of comparator B; with light loads it swings to within 200mV of the supply rails and with heavy loads to within 400mV.
7 OUT A output Output of comparator A; with light loads it swings to within 200mV of the supply rails and with heavy loads to within 400mV.
8 VCC power_in Positive supply voltage; operating range is 2.7V to 6V, with a 7V absolute maximum.
