The MAX547 contains eight 13-bit, voltage-output digital-toanalog converters (DACs). On-chip precision output amplifiers provide the voltage outputs. The MAX547 operates from a 5V supply. Bipolar output voltages with up to 4.5V voltage swing can be achieved with no external components. The MAX547 has four separate reference inputs; each is connected to two DACs, providing different fullscale output voltages for every DAC pair. The MAX547 features double-buffered interface logic with a 13-bit parallel data bus. Each DAC has an input latch and a DAC latch. Data in the DAC latch sets the output voltage. The eight input latches are addressed with three address lines. Data is loaded to the input latch with a single write instruction. --
