T he AD7224 is a precision 8-bit voltage-output, digital-to-

analog 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.

1. DAC and Amplifier on CMOS Chip

T he single-chip design of the 8-bit DAC and output amplifier

is inherently more reliable than multi-chip designs. CMOS

fabrication means low power consumption (35 mW typical

with single supply).

T he double buffered interface logic consists of two 8-bit regis-

ters–an input register and a DAC register. Only the data held in

the DAC registers determines the analog output of the con-

verter. T he double buffering allows simultaneous update in a

system containing multiple AD7224s. 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 cali-

bration cycles. All logic inputs are T T L and CMOS (5 V) level

compatible and the control logic is speed compatible with most

8-bit microprocessors.

2. Low T otal Unadjusted Error

T he fabrication of the AD7224 on Analog Devices Linear

Compatible CMOS (LC²MOS) process coupled with a novel

DAC switch-pair arrangement, enables an excellent total un-

adjusted error of less than 1 LSB over the full operating tem-

perature range.

3. Single or Dual Supply Operation

T he voltage-mode configuration of the AD7224 allows opera-

tion from a single power supply rail. T he part can also be op-

erated with dual supplies giving enhanced performance for

some parameters.

Specified performance is guaranteed for input reference voltages

from +2 V to +12.5 V when using dual supplies. T he part is also

specified for single supply operation using a reference of +10 V.

T he output amplifier is capable of developing +10 V across a

2 kΩ load.

4. Versatile Interface Logic

T he high speed logic allows direct interfacing to most micro-

processors. Additionally, the double buffered interface en-

ables simultaneous update of the AD7224 in multiple DAC

systems. T he part also features a zero override function.

T he AD7224 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.
