XL7650-8

XINLUDA · Operational Amplifier · SOP-8

XL7650-8 from XINLUDA, in a SOP-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 CEXTA passive External nulling capacitor A. Stores the correcting nulling potential; typically 0.1uF film capacitor (mylar or polypropylene preferred for low dielectric absorption).
2 -IN input Inverting input of the op-amp. High-impedance input with extremely low bias current (10pA max). Common-mode range +3.5V to -5V.
3 +IN input Non-inverting input of the op-amp. High-impedance input with extremely low bias current (10pA max). Common-mode range +3.5V to -5V.
4 V- power_in Negative supply rail. Total supply (V+ to V-) must not exceed 8V absolute maximum. Typical supply current 2mA.
5 CRETN passive Capacitor return. Low-impedance return node for the external nulling capacitors CEXTA and CEXTB.
6 OUTPUT output Amplifier output. High-impedance stage (~18k) internally compensated for unity gain. Best frequency response with load >=10k; short-circuit safe for indefinite duration.
7 V+ power_in Positive supply rail. Total supply (V+ to V-) must not exceed 8V absolute maximum. Typical supply current 2mA.
8 CEXTB passive External nulling capacitor B. Stores the correcting nulling potential; typically 0.1uF film capacitor (mylar or polypropylene preferred for low dielectric absorption).
