BH2222FV Standard ICs 8bit 20ch D/A converter BH2222FV BH2222FV is an 8bit D/A converter for electronic adjustment. The 20-channel output voltage can be independently controlled by three-wire serial interface from micro-controller. The built-in power on reset circuit keeps the output state Low after the power is on. 4-channel have data register function. Two kinds of set voltage can be retained, and output voltage can be switched by SEL pin. zApplications The voltage adjustment for DVC, DSC et.
