Bus Structured Instruments GENERAL DESCRIPTION The AD7524 is a low cost, 8-bit monolithic CMOS DAC
designed for direct interface to most microprocessors.
Basically an 8-bit DAC with input latches, the AD7524’s load
cycle is similar to the “write” cycle of a random access
memory. Using an advanced thin-film on CMOS fabrication
process, the AD7524 provides accuracy to 1/8 LSB with a typical power dissipation of less than 10 milliwatts.
A newly improved design eliminates the protection Schottky
previously required and guarantees TTL compatibility when
using a +5 V supply. Loading speed has been increased for …
