XBL8551S

XBLW · Precision Op Amps · SOT-23-5

XBL8551S from XBLW, in a SOT-23-5. 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 output Amplifier output. Rail-to-rail output swing; short-circuit source current typ 40 mA and sink typ 50 mA. Recommended to drive capacitive loads up to 500 pF directly; use series R_ISO for larger loads.
2 -Vs power_in Negative (lowest) power supply. Total supply voltage (Vs+ to Vs-) 1.8 V to 5.5 V (10 V absolute maximum). Typically tied to ground in single-supply applications.
3 +IN input Non-inverting input of the amplifier. Rail-to-rail input common-mode range from Vs- - 0.1 V to Vs+ + 0.1 V. Very high input impedance (typ 100 GOhm) and low input bias current (typ 70 pA).
4 -IN input Inverting input of the amplifier. Rail-to-rail input common-mode range from Vs- - 0.1 V to Vs+ + 0.1 V. Very high input impedance (typ 100 GOhm) and low input bias current (typ 70 pA).
5 +Vs power_in Positive (highest) power supply. Supply range 1.8 V to 5.5 V (10 V abs max Vs+ to Vs-). Bypass with a local 0.1 uF ceramic capacitor to -Vs.
