RS222XK 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 | OUT A | output | Output of amplifier A; the datasheet gives no output-specific limit beyond the rail-to-rail swing and a source current of 27 mA typical. |
| 2 | -IN A | input | Inverting input of amplifier A; input terminals are diode-clamped to the supply rails and must stay within -0.5V to (V+)+0.5V, with input current limited to ±10 mA. |
| 3 | +IN A | input | Non-inverting input of amplifier A; common-mode range is -0.1V to 5.6V with Vs = 5.5V. |
| 4 | V- | power_in | Negative supply rail; the part operates from 2.5V to 5.5V total supply (±1.25V to ±2.75V) and the absolute maximum V+ to V- is 7.0V. |
| 5 | +IN B | input | Non-inverting input of amplifier B; common-mode range is -0.1V to 5.6V with Vs = 5.5V. |
| 6 | -IN B | input | Inverting input of amplifier B; input terminals are diode-clamped to the supply rails and must stay within -0.5V to (V+)+0.5V, with input current limited to ±10 mA. |
| 7 | OUT B | output | Output of amplifier B; the datasheet gives no output-specific limit beyond the rail-to-rail swing and a source current of 27 mA typical. |
| 8 | V+ | power_in | Positive supply rail; the part operates from 2.5V to 5.5V total supply, with an absolute maximum V+ to V- of 7.0V. |
