Description
The AD7523 and AD7533 are monolithic, low cost, high
performance, 8-bit and 10-bit accurate, multiplying digital-to-
analog converter (DAC), in a 16 pin DIP.
Intersil’ thin film resistors on CMOS circuitry provide 10-bit
resolution (8-bit, 9-bit and 10-bit accuracy), with TTL/CMOS
compatible operation.
The AD7523 and AD7533s accurate four quadrant
multiplication, full military temperature range operation, full
input protection from damage due to static discharge by
clamps to V+ and GND, and very low power dissipation
make it a very versatile converter.
Low noise audio gain controls, motor speed controls,
digitally controlled gain and digital attenuators are a few of
the wide range of applications of the AD7523 and AD7533.
