AD7520, AD7521
10-Bit, 12-Bit, Multiplying D/A Converters
The AD7520 and AD7521 are monolithic, high accuracy, low
cost 10-bit and 12-bit resolution, multiplying digital-to-analog
converters (DAC). Intersil’s thin-film on CMOS processing
gives up to 10-bit accuracy with TTL/CMOS compatible
operation. Digital inputs are fully protected against static
discharge by diodes to ground and positive supply.
Typical applications include digital/analog interfacing,
multiplication and division, programmable power supplies,
CRT character generation, digitally controlled gain circuits,
integrators and attenuators, etc.
