rs522xk.lbr rebuild the library on adom-lbr 2.32.0. The published copy was built by 2.18.0, which imported every KiCad roundrect and oval pad as a SQUARE EAGLE smd; this carries the real pad shape across (0 -> 8 rounded pads) and stops dropping geometry drawn on KiCad User.N layers. Attributes, connects, pads and the pin-1 marker are gated against decreasing and are unchanged. · Ray 1mo ago

RS522XK

Jiangsu RUNIC Tech · Operational Amplifier · SOIC-8

RS522XK from Jiangsu RUNIC Tech, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 OUT A output Amplifier A output. Rail-to-rail push-pull CMOS output; swings within ~7mV of the rails at RL=10kOhm and delivers ~80mA short-circuit current.
2 -IN A input Inverting input of amplifier A. High-impedance CMOS input, IB ~1pA typical, common-mode range -0.1V to +5.6V at Vs=5.5V. Diode-clamped to the supply rails.
3 +IN A input Non-inverting input of amplifier A. High-impedance CMOS input, rail-to-rail common-mode range (-0.1V to Vs+0.1V). Input signals more than 0.5V beyond the rails must be current-limited to 10mA.
4 V- power_in Negative supply / ground. In single-supply operation tie to GND; in split-supply operation connect to the negative rail. Total supply span V+ to V- must not exceed 7.0V (absolute maximum).
5 +IN B input Non-inverting input of amplifier B. High-impedance CMOS input, rail-to-rail common-mode range (-0.1V to Vs+0.1V).
6 -IN B input Inverting input of amplifier B. High-impedance CMOS input, IB ~1pA typical.
7 OUT B output Amplifier B output. Rail-to-rail push-pull CMOS output; ~80mA short-circuit current, unity-gain stable driving CL=100pF.
8 V+ power_in Positive supply. Operating range +2.5V to +5.5V referenced to V-. Bypass with a 0.1uF ceramic (and 10uF bulk) placed close to the pin per the datasheet layout guidance.
