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 typi-

cal 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

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.

FEATURES

Microprocessor Compatible (6800, 8085, Z80, Etc.)

TTL/CMOS Compatible Inputs

On-Chip Data Latches

Endpoint Linearity

Low Power Consumption

Monotonicity Guaranteed (Full Temperature Range)

Latch Free (No Protection Schottky Required)

APPLICATIONS

Microprocessor Controlled Gain Circuits

Microprocessor Controlled Attenuator Circuits

Microprocessor Controlled Function Generation

Precision AGC Circuits
