DIN: The Serial Interface Data. CS/LD: The Serial Interface Enable and Load Control. When CS/LD is low the CLK signal is enabled, so the data can be clocked in. When CS/LD is pulled high data is loaded from the shift register into the DAC registers, updating the DAC outputs. DOUT: The output of the shift register which becomes valid on the rising edge of the serial clock. GND: Ground. VOUT A,VOUT B: Buffered DAC Outputs. VCC: Positive Supply Input. 4.5V ≤ VCC ≤ 5.5V (LTC1446), 2.7V ≤ VCC ≤ 5.5V (LTC1446L). Requires a bypass capacitor to ground.
