Jiangsu RUNIC Tech · Operational Amplifier · SOIC-8
RS8702XK from Jiangsu RUNIC Tech, in a SOIC-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 | Output of channel A; the datasheet states the output is short-circuit protected to ground with a continuous short-circuit rating, one amplifier per package. |
| 2 | -INA | input | Inverting input of channel A; input signals that swing more than 0.5 V beyond the supply rails should be current-limited to 10 mA or less. |
| 3 | +INA | input | Noninverting input of channel A; the input common-mode range includes both supply rails, and input signals that swing more than 0.5 V beyond the supply rails should be current-limited to 10 mA or less. |
| 4 | V- | power_in | Negative (lowest) power supply; the supply range (V+) - (V-) is 2.2 V to 5.5 V single-supply. |
| 5 | +INB | input | Noninverting input of channel B; the input common-mode range includes both supply rails, and input signals that swing more than 0.5 V beyond the supply rails should be current-limited to 10 mA or less. |
| 6 | -INB | input | Inverting input of channel B; input signals that swing more than 0.5 V beyond the supply rails should be current-limited to 10 mA or less. |
| 7 | OUTB | output | Output of channel B; the datasheet states the output is short-circuit protected to ground with a continuous short-circuit rating, one amplifier per package. |
| 8 | V+ | power_in | Positive (highest) power supply; the supply range (V+) - (V-) is 2.2 V to 5.5 V single-supply, with absolute maximum 5.5 V. |
