**Linearin** · Comparators · MSOP-8

LTC8702YV8 from Linearin, in a MSOP-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 | OUTA | output | Comparator A push-pull output, which pulls to within 0.1 V of either supply rail and tolerates a continuous short circuit to either rail. |
| 2 | -INA | input | Comparator A negative input, with a voltage range from (VS- - 0.1 V) to (VS+ + 0.1 V). |
| 3 | +INA | input | Comparator A positive input, with the 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 | +INB | input | Comparator B positive input, with the same voltage range as -IN, (VS- - 0.1 V) to (VS+ + 0.1 V). |
| 6 | -INB | input | Comparator B negative input, with a voltage range from (VS- - 0.1 V) to (VS+ + 0.1 V). |
| 7 | OUTB | output | Comparator B push-pull output, which pulls to within 0.1 V of either supply rail and tolerates a continuous short circuit to either rail. |
| 8 | +VS | power_in | Positive power supply, 1.7 V to 5.5 V between VS+ and VS- (split supplies are allowed within that span). |
