ALD1801

ADVANCED LINEAR DEVICES, INC. ALD1801A/ALD1801B ALD1801 8 BIT MICROPOWER MULTIPLYING D/A CONVERTER 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’ "FunctionSpecific" 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.
