● Easy Interface to MicroprocessorsGENERAL DESCRIPTION
Data is transferred to either of the two D/A Converter latches via a common 8-bit TTL/5 V CMOS compatible input port. The control input DAC A/DAC B determines which D/A is to be loaded. The device operates from a 4.5 V to 5.5 V power supply, and is TTL-compatible over this range. Power dissipation is only 10 mW. Both DACs offer excellent four quadrant multiplication characteristics, and include separate reference inputs and feedback resistors. An improved latch-up resistant design eliminates the need for external protective Schottky diodes in most applications.
