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.
