RS8920XK-G

Jiangsu RUNIC Tech · Comparators · SOP-8

RS8920XK-G from Jiangsu RUNIC Tech, 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 OUTA output Channel A open-drain comparator output, which needs an external pull-up and may be wire-ANDed with other open-collector outputs.
2 -INA input Channel A inverting input; the common-mode voltage range is V- to (V+) - 1.5V, and input signals should stay within (V-) - 0.3V to (V+) + 0.3V.
3 +INA input Channel A noninverting input with the same common-mode range of V- to (V+) - 1.5V, and input signals beyond the rails by more than 0.3V should be current-limited to 10mA or less.
4 V- power_in Negative (lowest) power supply; the device runs from 2.8V to 36V single-supply or ±1.4V to ±18V dual-supply.
5 +INB input Channel B noninverting input with the same common-mode range of V- to (V+) - 1.5V, and input signals beyond the rails by more than 0.3V should be current-limited to 10mA or less.
6 -INB input Channel B inverting input; the common-mode voltage range is V- to (V+) - 1.5V, and input signals should stay within (V-) - 0.3V to (V+) + 0.3V.
7 OUTB output Channel B open-drain comparator output, which needs an external pull-up and may be wire-ANDed with other open-collector outputs.
8 V+ power_in Positive (highest) power supply; the supply range is 2.8V to 36V with an absolute maximum of 40V.
