# RS8452XK

**Jiangsu RUNIC Tech** · Operational Amplifier · SOP-8

RS8452XK 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 | Output of channel A. |
| 2 | -INA | input | Inverting input of channel A; the common-mode range is (V-) to (V+)-2V per the electrical characteristics. |
| 3 | +INA | input | Noninverting input of channel A; the input can operate from the negative rail up to 2V below the positive rail. |
| 4 | V- | power_in | Negative (lowest) power supply or ground for single-supply operation; single-supply range is 5V to 36V with respect to V+. |
| 5 | +INB | input | Noninverting input of channel B; the input can operate from the negative rail up to 2V below the positive rail. |
| 6 | -INB | input | Inverting input of channel B; the common-mode range is (V-) to (V+)-2V per the electrical characteristics. |
| 7 | OUTB | output | Output of channel B. |
| 8 | V+ | power_in | Positive (highest) power supply; total supply Vs = (V+) - (V-) must stay within 5V to 36V single-supply or ±2.5V to ±18V dual-supply. |
