MOS INTEGRATED CIRCUIT

µPD6222

DESCRIPTION

The

µPD6222 is an 8-bit monolithic CMOS digital-to-analog converter using the R-2R technique. The µPD6222

incorporates a 12-channel digital-to-analog converters and I2C-bus compatible interface. The designer needs only

2 signals (Serial Data and Serial Clock) to interface and can use 8-ICs (96-channels) on same bus to control chip-

select terminals.

The

µPD6222 incorporates Output CMOS Buffer to achieve wide output voltage range and two reference voltage

terminals.

The

µPD6222 is ideal for automatic control for color-television.
