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 etc.

zFeatures
1) 8bit 20-channel D/A converters adopting R-2R system.
2) 3-wire + 1-wire 16-bit serial interface.
3) POWER ON RESET circuit.
4) The full scale output voltage range : 2.7 ~ 5.5V.
5) It is possible to set the two output full scale level independently.
6) 4-channel date Register extension function.
