GENERAL DESCRIPTION
The AD7545 is a monolithic 12-bit CMOS multiplying DAC with onboard data latches. It is loaded by a single 12-bit wide word and directly interfaces to most 12- and 16-bit bus systems. Data is loaded into the input latches under the control of the CS and WR inputs; tying these control inputs low makes the input latches transparent, allowing direct unbuffered operation of the DAC.
The AD7545 is particularly suitable for single supply operation and applications with wide temperature variations....
