Description

The AD7224KR-18 is a precision 8-bit voltage-output, digital-toanalog converter, with output amplifier and double buffered interface logic on a monolithic CMOS chip. No external trims are required to achieve full specified performance for the part.The double buffered interface logic consists of two 8-bit registersan input register and a DAC register. Only the data held in the DAC registers determines the analog output of the converter.The double buffering allows simultaneous update in a system containing multiple AD7224KR-18s. Both registers may be made transparent under control of three external lines, CS, WR and LDAC. With both registers transparent, the RESET line functions like a zero override; a useful function for system calibration cycles. All logic inputs are TTL and CMOS (5 V) level compatible and the control logic is speed compatible with most 8-bit microprocessors.

Specified performance is guaranteed for input reference voltages from +2 V to +12.5 V when using dual supplies. The part is also specified for single supply operation using a reference of +10 V.The output amplifier is capable of developing +10 V across a 2 k load.The AD7224KR-18 is fabricated in an all ion-implanted high speed Linear Compatible CMOS (LC2MOS) process which has been specifically developed to allow high speed digital logic circuits and precision analog circuits to be integrated on the same chip.
