TYPICAL PERFOR A CE CHARACTERISTICS
CLK (Pin 1): The TTL Level Input for the Serial Interface
Clock.
D
Data. Data on the D
on the rising edge of the serial clock and is loaded MSB
first. The LTC1658 requires a 16-bit word to be loaded in.
The last two bits are don’t cares.
CS/LD (Pin 3): The TTL Level Input for the Serial Inter-
face 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 register, updating the DAC output.
