Isolated_D_A_converters_with_serial_input

Published:2009/7/24 10:24:00 Author:Jessie | From:SeekIC

In this circuit, two MAX543 serial-input 12-bit D/A converters (DACs) receive power and data from a MAX250 receiver/transmitter. Clock and data lines are shared by both DACs, but separate LOAD1 and LOAD2 inputs latch the data in. The MAX250 also has a shutdown input (SHDN) that powers down the circuit and cuts supply current to less than 10μA. Maxim, 1992, Applications and Product Highlights, p. 2-9.
