GENERAL D ESCRIP TIO N
T he AD7524 is a low cost, 8-bit monolithic CMOS DAC
designed for direct interface to most microprocessors.
O RD ERING GUID E
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 typi-
cal power dissipation of less than 10 milliwatts.

A newly improved design eliminates the protection Schottky
previously required and guarantees T T L compatibility when
using a +5 V supply. Loading speed has been increased for
compatibility with most microprocessors.
Featuring operation from +5 V to +15 V, the AD7524 inter-
faces directly to most microprocessor buses or output ports.
Excellent multiplying characteristics (2- or 4-quadrant) make
the AD7524 an ideal choice for many microprocessor con-
trolled gain setting and signal control applications.
