2 I2C-BUS COMPATIBLE OCTAL 8BIT D/A CONVERTER

DESCRIPTION The UD6221 is an 8-bit monolithic CMOS digital-to-analog converter using the R-2R technique. The UD6221 2 incorporates an 8-channel digital-to-analog converters and I C-bus compatible Interface The designer needs only 2 signals (Serial Data and Serial Clock) to Interface and CAN use 8-ICs (64-channels) on same bus to control chip- select terminals. The UD6221 incorporates Output CMOS Buffer to achieve wide output voltage range and two reference voltage terminals. The UD6221 is ideal for Automatic control for color-television.
