GENERAL DESCRIPTION
The ALD1801 is an 8-bit monolithic current output digital to analog
converter designed to provide low power, low operating voltage and simple
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.
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, as it is fully compatible in design, operation, and manufacture
with all other linear elements in Advanced Linear Devices’ product family.
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.
