8-Bit, Multiplying D/A Converters
Features
Description
• 8-Bit, 9-Bit and 10-Bit Linearity
• Low Gain and Linearity Temperature Coefficients
• Full Temperature Range Operation
• Static Discharge Input Protection
• TTL/CMOS Compatible
• Supply Range . . . . . . . . . . . . . . . . . . . . . . . . +5V to +15V
• Fast Settling Time at 25oC . . . . . . . . . . . . 150ns (Max)
• Four Quadrant Multiplication
• AD7533 Direct AD7520 Equivalent
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.
