BH2220FVM
BH2220FVM is 8bit 3 channel D/A converter for electronic adjustment. The 3-channel DC output can be independently
controlled by three-wire serial interface from micro-controller.
The D/A converter can generate without loss by Rail to Rail output within the setting voltage.
This small MSOP8 package is suitable for portable appliances.
!Applications
The voltage adjustment for DVC, DSC etc.
!Features
1) 8bit 3-channel D/A converters adopting R-2R system.
2) 3-wire 10-bit serial interface.
3) POWER ON RESET circuit.
4) The full scale output voltage range : 2.7V∼5.5V.
5) MSOP8 package.
