s DATA CONFIGURATION

The MB88347L has a 12-bit shift register for chip control.

The 12-bit shift register must be used to set up data in the configuration shown below.

The data configuration has a total of 12 bits, for address selection and eight for D/A data output.

• D/A converter control signals

Note: VLB = (VDD – VSS)/256

• Address selection signals
