12-Bit, Buffered, Multiplying CMOS DAC
Description
The AD7545 is a low cost monolithic 12-bit, CMOS
multiplying DAC with on-board data latches. Data is loaded
in a single 12-bit wide word which allows interfacing directly
to most 12-bit and 16-bit bus systems. Loading of the input
latches is under the control of the CS and WR inputs. A logic
low on these control inputs makes the input latches transpar-
ent allowing direct unbuffered operation of the DAC.
