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.  
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.  
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 WR goes low. The control logic is speed-compat-  
ible with most 8-bit microprocessors.  
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.  
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.  
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.  
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 (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.
