vs Temperature

CLK: The Serial Interface Clock.

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.

on the rising edge of the serial clock.

GND: Ground.

4.5V

(LTC1446L). Requires a bypass capacitor to ground.
