DAC1008 Datasheet | National Semiconductor

Description The DAC1006 7 8 are advanced CMOS Si-Cr 10- 9- and 8-bit accurate multiplying DACs which are designed to interface directly with the 8080 8048 8085 Z-80 and other popular microprocessors These DACs appear as a memory location or an I O port to the m P and no interfacing logic is needed These devices bined with an external amplifier and voltage reference can be used as standard D A converters and they are very attractive for multiplying applications (such as digitally controlled gain blocks) since their linearity error is essentially independent of the voltage reference They bee equally attractive in audio signal processing equipment as audio gain controls or as programmable attenuators which marry high quality audio signal processing to digitally based systems under microprocessor control All of these DACs are double buffered They can load all 10 bits or two 8-bit bytes and the data format is left justified The analog section of these DACs is essentially the same as that of the DAC1020 The DAC1006 series are the 10-bit members of a family of microprocessor-patible DAC’s (MICRO-DACTM ’s) For applications requiring other resolutions the DAC0830 series (8 bits) and the DAC1208 and DAC1230 (12 bits) are available alternatives Part DAC1006 DAC1007 DAC1008 Accuracy (bits) 10 9 8 20 Pin Description Features Y Y Y Y Y Uses easy to adjust END POINT specs NOT BEST STRAIGHT LINE FIT Low power consumption Direct interface to all popular microprocessors Integrated thin film on CMOS structure Double-buffered single-buffered or flow through digital data inputs Loads two 8-bit bytes or a single 10-bit word Logic inputs which meet TTL voltage level specs (1 4V logic threshold) Works with g 10V reference full 4-quadrant multiplication Operates STAND ALONE (without m P) if desired Available in 0 3 standard 20-pin package Differential non-linearity selection available as special order Key Specifications Output Current Settling Time Resolution...
