DAC1243 Overview
Features PRELIMINARY The DAC1242/1243 are 12-bit digital-to-analog converters with 4-20mA current loop output. The DAC1242 is a current-sinking device, while the DAC1243 provides true current sourcing into a ground referenced load. The digital input registers are similar to an INS8255, allowing direct TTL interfacing to a variety of 8-bit microprocessors (8080, 8085, 8048, 8070, 8073, NSC800, Z80, et al).
