AD5724/AD5734/AD5754 THEORY OF OPERATION The AD5724/AD5734/AD5754 are quad, 12-/14-/16-bit, serial input, unipolar/bipolar, voltage output DACs. They operate from unipolar supply voltages of +4 +16 bipolar supply voltages of ±4 ±16 addition, the ...
Page 19
Standalone Operation The serial interface works with both a continuous and noncon- tinuous serial clock. A continuous SCLK source can be used only if SYNC is held low for the correct number of clock cycles. In gated clock mode, a ...
