GENERAL D ESCRIP TIO N

T he AD7225 contains four 8-bit voltage output digital-to-

analog converters, with output buffer amplifiers and interface

logic on a single monolithic chip. Each D/A converter has a

separate reference input terminal. No external trims are re-

quired to achieve full specified performance for the part.

1. DACs and Amplifiers on CMOS Chip

T he single-chip design of four 8-bit DACs and amplifiers al-

lows a dramatic reduction in board space requirements and

offers increased reliability in systems using multiple convert-

ers. Its pinout is aimed at optimizing board layout with all

analog inputs and outputs at one end of the package and all

digital inputs at the other.

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

ters per channel–an input register and a DAC register. Control

inputs A0 and A1 determine which input register is loaded when

WR goes low. Only the data held in the DAC registers deter-

mines the analog outputs of the converters. T he double-

buffering allows simultaneous update of all four outputs under

control of LDAC. 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. Single or Dual Supply Operation

T he voltage-mode configuration of the AD7225 allows single

supply operation. T he part can also be operated 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.

Each output buffer amplifier is capable of developing +10 V

across a 2 kΩ load.

3. Versatile Interface Logic

T he AD7225 has a common 8-bit data bus with individual

DAC latches, providing a versatile control architecture for

simple interface to microprocessors. T he double-buffered in-

terface allows simultaneous update of the four outputs.

T he AD7225 is fabricated on an all ion-implanted high-speed

Linear Compatible CMOS (LC²MOS) process which has been

specifically developed to integrate high speed digital logic cir-

cuits and precision analog circuitry on the same chip.

4. Separate Reference Input for Each DAC

T he AD7225 offers great flexibility in dealing with input sig-

nals with a separate reference input provided for each DAC

and each reference having variable input voltage capability.
