BL6290

BL(Shanghai Belling) · Audio Power OpAmps · SOP-8

BL6290 from BL(Shanghai Belling), in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 SHD input Shut-down logical control; a logic '0' is the active state that places the amplifier in shutdown.
2 BP bidirectional Analog ground for the inner OPAs, held at about half of VDD and bypassed with Cb.
3 INP input Positive (non-inverting) amplifier input.
4 INN input Negative (inverting) amplifier input.
5 Vout1 output Negative BTL output.
6 VDD power_in Power supply, 2.2 V to 5.5 V per the operating ratings.
7 GND power_in Ground reference.
8 Vout2 output Positive BTL output.
