8 BIT MICROPOWER MULTIPLYING D/A CONVERTER  
FEATURES  
GENERAL DESCRIPTION  
• Low voltage 3V to 12V operation  
• Low power 1.8mW max @ 3.3V  
• Single supply operation (5V or 3.3V)  
• Direct CMOS logic interface  
• Complementary current outputs  
• Nonlinearity to 0.1% max over  
temperature range  
The ALD1801 is an 8-bit monolithic current output digital to analog  
converterdesignedtoprovidelowpower, lowoperatingvoltageandsimple  
operation. It offers industry pin configuration of DAC-08 types, and is  
intended for a wide range of digital to analog conversion and control  
applications in +5V single power supply and ±5V dual power supply  
systems, as well as +3V to +12V battery operated systems. Device  
characteristics are specified for +5V single supply and 3.3V dual supply  
systems.  
• High input impedance  
• Low full scale current  
• High output impedance  
The ALD1801 is manufactured with Advanced Linear Devices’ enhanced  
ACMOS silicon gate CMOS process and has been designed to be also  
used as a linear cell element in Advanced Linear Devices’ "Function-  
Specific"ASIC,asitis fullycompatibleindesign,operation,andmanufacture  
with all other linear elements in Advanced Linear Devices’ product family.

N/C  
The ALD1801 is designed with matching between reference and full scale  
currents. Digital inputs are standard CMOS logic inputs to provide ease  
of interface. Output currents can be directly converted to a voltage output  
by using a pair of resistors. When used with ALD’s rail-to-rail output  
operational amplifiers such as the ALD1702, full scale output of 0 to +5V  
can be easily achieved with single +5V power supply.
