GENERAL DESCRIPTION
The AD7545A, a 12-bit CMOS multiplying DAC with internal
data latches, is an improved version of the industry standard
AD7545. This new design features a WR pulse width of 100 ns,
which allows interfacing to a much wider range of fast 8-bit and
16-bit microprocessors. It is loaded by a single 12-bit-wide word
under the control of the CS and WR inputs; tying these control
inputs low makes the input latches transparent, allowing unbuf-
fered operation of the DAC.
