RS622AXQ

Jiangsu RUNIC Tech · Operational Amplifier · TSSOP-8

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.
