uPD6222 Datasheet | Renesas

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 patible 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 chipselect 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. FEATURES - 12-channel 8-bit digital-to-analog converter using the R-2R ladder technique - I2C-bus patible serial interface (Serial Data and Serial Clock) - 8-ICs (96-channels) can be connected by chip-select terminals - Output CMOS Buffer to achieve wide output voltage range - Two reference voltage ORDERING INFORMATION PART NO. µPD6222CS µPD6222GS PACKAGE 24-pin plastic shrink DIP (300 mil) 24-pin plastic SOP (300 mil) Caution Purchase of NEC I2C ponents conveys a license under the Philips I2C patent Right to use these ponents in an I2C system, provided that the system conforms to the I2C Standard Specification as defined by Philips.
