GENERAL DESCRIPTION

PRODUCT HIGHLIGHTS

The AD7226 contains four 8-bit voltage-output digital-to-

analog converters, with output buffer amplifiers and interface

logic on a single monolithic chip. No external trims are required

to achieve full specified performance for the part.

Separate on-chip latches are provided for each of the four D/A

converters. Data is transferred into one of these data latches

through a common 8-bit TTL/CMOS (5 V) compatible input

port. Control inputs A0 and A1 determine which DAC is

loaded when

goes low. The control logic is speed-compat-

ible with most 8-bit microprocessors.

Each D/A converter includes an output buffer amplifier capable

of driving up to 5 mA of output current. The amplifiers’ offsets

are laser-trimmed during manufacture, thereby eliminating any

requirement for offset nulling.

Specified performance is guaranteed for input reference voltages

from 2 V to 12.5 V with dual supplies. The part is also specified

for single supply operation at a reference of 10 V.

The AD7226 is fabricated in an all ion-implanted high speed

Linear Compatible CMOS (LC

MOS) process, which has been

specifically developed to allow high speed digital logic circuits

and precision analog circuits to be integrated on the same chip.

1. DAC-to-DAC Matching

Since all four DACs are fabricated on the same chip at the

same time, precise matching and tracking between the DACs

is inherent.

2. Single-Supply Operation

The voltage mode configuration of the DACs allows the

AD7226 to be operated from a single power supply rail.

3. Microprocessor Compatibility

The AD7226 has a common 8-bit data bus with individual

DAC latches, providing a versatile control architecture for

simple interface to microprocessors. All latch enable signals

are level triggered.

4. Small Size

Combining four DACs and four op amps plus interface logic

into a 20-pin package allows a dramatic reduction in board

space requirements and offers increased reliability in systems

using multiple converters. Its pinout is aimed at optimizing

board layout with all the analog inputs and outputs at one

end of the package and all the digital inputs at the other.
