Gainsil · Comparators · SOP-8
GS8705-SR from Gainsil, in a SOP-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 | INA+ | input | Non-inverting input of comparator A, rail-to-rail with common-mode range of -0.1V to +5.6V at VS = 5.5V. |
| 2 | INA- | input | Inverting input of comparator A, rail-to-rail with common-mode range of -0.1V to +5.6V at VS = 5.5V. |
| 3 | INB+ | input | Non-inverting input of comparator B, rail-to-rail with common-mode range of -0.1V to +5.6V at VS = 5.5V. |
| 4 | INB- | input | Inverting input of comparator B, rail-to-rail with common-mode range of -0.1V to +5.6V at VS = 5.5V. |
| 5 | VSS | power_in | Negative supply or ground; VDD to VSS is rated -0.5V to +7.5V absolute maximum. |
| 6 | OUTB | output | Push-pull, rail-to-rail, CMOS/TTL-compatible output of comparator B, short-circuit source 22mA and sink 20mA typical at VS = 5V. |
| 7 | OUTA | output | Push-pull, rail-to-rail, CMOS/TTL-compatible output of comparator A, short-circuit source 22mA and sink 20mA typical at VS = 5V. |
| 8 | VDD | power_in | Positive supply, operating range 1.4V to 5.5V, with a 0.1uF ceramic bypass capacitor recommended close to the pin. |
