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. |
