RS8522XM

Jiangsu RUNIC Tech · Precision OpAmps · MSOP-8

RS8522XM from Jiangsu RUNIC Tech, in a MSOP-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 output: swings to within ~10 mV of V+ / V- with 10 kΩ load; typical short-circuit current 25 mA.
2 -IN A input Amplifier A inverting input. Rail-to-rail common-mode input range from (V-)-0.1 V to (V+)+0.1 V; input bias current ~10 pA typical.
3 +IN A input Amplifier A non-inverting input. Rail-to-rail common-mode input range from (V-)-0.1 V to (V+)+0.1 V; input bias current ~10 pA typical. Diode-clamped to supply rails; limit currents beyond rails to ≤10 mA.
4 V- power_in Negative supply / ground. Single supply operation: tie to GND. Dual-supply range: -1.25 V to -2.75 V. V+ to V- must not exceed 7 V absolute maximum.
5 +IN B input Amplifier B non-inverting input. Rail-to-rail common-mode input range from (V-)-0.1 V to (V+)+0.1 V; input bias current ~10 pA typical.
6 -IN B input Amplifier B inverting input. Rail-to-rail common-mode input range from (V-)-0.1 V to (V+)+0.1 V; input bias current ~10 pA typical.
7 OUT B output Amplifier B output. Rail-to-rail output: swings to within ~10 mV of V+ / V- with 10 kΩ load; typical short-circuit current 25 mA.
8 V+ power_in Positive supply. Operating range +2.5 V to +5.5 V (single supply) or ±1.25 V to ±2.75 V (dual). Bypass with a 0.1 uF ceramic close to the pin. V+ to V- absolute maximum 7 V.
