BH2223FV
BH2223FV is an 8bit D/A converter for electronic adjustment. The 10-channel DC output voltage 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. The built-in power on reset circuit keeps the output state Low after the power is on and
prevents the unstable output state.
!Applications
The voltage adjustment for DVC, DSC etc.
!Features
1) 8bit 10-channel D/A converters adopting R-2R system.
2) 3-wire 12-bit serial interface.
3) POWER ON RESET circuit.
4) The full scale output voltage range : 2.7V∼5.5V.
5) SSOPB16 package.
