RS122XK

Jiangsu RUNIC Tech · Operational Amplifier · SOP-8

RS122XK 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 OUT A output Amplifier A output, rail-to-rail with about 3mV swing from the rail at RL = 2kΩ and 25mA short-circuit current.
2 -IN A input Amplifier A inverting input, rail-to-rail, diode-clamped to the supplies and limited to ±10mA if driven beyond 0.5V past the rails.
3 +IN A input Amplifier A non-inverting input, rail-to-rail with a common-mode range of -0.1V to 5.6V at Vs = 5.5V.
4 V- power_in Negative supply (ground in single-supply use); total supply V+ to V- is 2.5V to 5.5V with 7.0V absolute maximum.
5 +IN B input Amplifier B non-inverting input, rail-to-rail with a common-mode range of -0.1V to 5.6V at Vs = 5.5V.
6 -IN B input Amplifier B inverting input, rail-to-rail, diode-clamped to the supplies and limited to ±10mA if driven beyond 0.5V past the rails.
7 OUT B output Amplifier B output, rail-to-rail with about 3mV swing from the rail at RL = 2kΩ and 25mA short-circuit current.
8 V+ power_in Positive supply, 2.5V to 5.5V relative to V- (7.0V absolute maximum), with a 0.1uF capacitor placed closely across the supply pins.
