PIN FUNCTIONS
BLOCK DIAGRAM
LTC2630
⎯ C ⎯ S /LD (Pin 1): Serial Interface Chip Select/Load Input.
When ⎯ C ⎯ S /LD is low, SCK is enabled for shifting data on
SDI into the register. When ⎯ C ⎯ S /LD is taken high, SCK
is disabled and the specifi ed command (see Table 1) is
executed.
SCK (Pin 2): Serial Interface Clock Input. CMOS and TTL
compatible.
SDI (Pin 3): Serial Interface Data Input. Data on SDI
is clocked into the DAC on the rising edge of SCK. The
LTC2630 accepts input word lengths of either 24 or 32
bits.
