LTC8722YS8 from Linearin, in a SOIC-8L. 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 | OUT A | output | Comparator A push-pull output, swings to within 0.1 V of either supply rail and tolerates continuous short-circuit to either rail. |
| 2 | -IN A | input | Comparator A negative input, voltage range from (VS- - 0.1 V) to (VS+ + 0.1 V). |
| 3 | +IN A | input | Comparator A positive input, same voltage range as -IN: (VS- - 0.1 V) to (VS+ + 0.1 V). |
| 4 | -VS | power_in | Negative power supply, normally tied to ground, or to another voltage as long as VS+ to VS- is 1.7 V to 5.5 V. |
| 5 | +IN B | input | Comparator B positive input, same voltage range as -IN: (VS- - 0.1 V) to (VS+ + 0.1 V). |
| 6 | -IN B | input | Comparator B negative input, voltage range from (VS- - 0.1 V) to (VS+ + 0.1 V). |
| 7 | OUT B | output | Comparator B push-pull output, swings to within 0.1 V of either supply rail and tolerates continuous short-circuit to either rail. |
| 8 | +VS | power_in | Positive power supply, 1.7 V to 5.5 V; split supplies allowed if VS+ to VS- is 1.7 V to 5.5 V. |
