RS622AXQ from Jiangsu RUNIC Tech, in a TSSOP-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 specifies rail-to-rail output with about 40 mV swing from the rail at RL=2kΩ and 7 mV at RL=10kΩ. |
| 2 | -IN A | input | Inverting input of amplifier A; input voltage must stay within the absolute maximum range of -0.5 V to (V+) + 0.5 V, with input current limited to ±10 mA. |
| 3 | +IN A | input | Non-inverting input of amplifier A; common-mode range is -0.1 V to 5.6 V at Vs = 5.5 V, and inputs are diode-clamped to the supply rails. |
| 4 | V- | power_in | Negative supply rail; the device operates from a single supply of 2.5 V to 5.5 V (or dual ±1.25 V to ±2.75 V) and the absolute maximum supply voltage V+ to V- is 7.0 V. |
| 5 | +IN B | input | Non-inverting input of amplifier B; common-mode range is -0.1 V to 5.6 V at Vs = 5.5 V, and inputs are diode-clamped to the supply rails. |
| 6 | -IN B | input | Inverting input of amplifier B; input voltage must stay within the absolute maximum range of -0.5 V to (V+) + 0.5 V, with input current limited to ±10 mA. |
| 7 | OUT B | output | Output of amplifier B; the datasheet specifies rail-to-rail output with about 40 mV swing from the rail at RL=2kΩ and 7 mV at RL=10kΩ. |
| 8 | V+ | power_in | Positive supply rail; the device operates from 2.5 V to 5.5 V and the absolute maximum supply voltage V+ to V- is 7.0 V. |
