Description

BH2221FV is an 8bit D/A converter for electronic adjustment. The 12-channel DC output voltage can be independently controlled by three-wire serial interface from micro-controller. The D/A converter BH2221FV 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.
