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.
