TYPICAL PERFORMANCE CHARACTERISTICS
I
the DAC current output can be biased from – 15V to 2V or
– 15V to 2.5V respectively.
V
supply must be kept free from noise and ripple by bypass-
ing directly to the ground plane.
SHDN (Pin 3): Shutdown. A logic low puts the chip
into Shutdown mode. The digital setting for the DAC is
retained.
CLK (Pin 4): Shift Clock. This clock synchronizes the serial
data in 3-wire mode. This pin has a Schmitt trigger input.

CS (Pin 5): Chip Select Input. In 3-wire mode, a logic low
on this CS pin enables the LTC1329. Upon power-up, a
logic high at CS puts the chip into pulse mode. If CS ever
goes low, the chip is configured in 3-wire mode until the
next power is cycled.
GND (Pin 6): Ground. Ground should be tied directly to a
ground plane.

data is shifted into D
mode, upon power-up a logic high at D
