应用功能:10-Bit, 12-Bit, Multiplying D/A Converters The AD7520/AD7530 and AD7521/AD7531 are monolithic,high accuracy, low cost 10-bit and 12-bit resolution,multiplying digital-to-analog converters (DAC). Intersil’thin-film on CMOS processing gives up to 10-bit accuracywith TTL/CMOS compatible operation. Digital inputs are fullyprotected against static discharge by diodes to ground andpositive supply.
