AD7533
FN3105.3
10-Bit Multiplying D/A Converter
The AD7533 is a monolithic, low cost, high performance,
10-bit accurate, multiplying digital-to-analog converter
(DAC), in a 16 pin DIP.
Intersil’s thin film resistors on CMOS circuitry provide 10-bit
resolution (8-bit accuracy), with TTL/CMOS compatible
operation.
The AD7533’s accurate four quadrant multiplication, full
input protection from damage due to static discharge by
clamps to V+ and GND, and very low power dissipation
make them very versatile converters.
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 AD7533.
