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. |
