LTC2604/LTC2614/LTC2624
TYPICAL PERFOR A CE CHARACTERISTICS
(LTC2614)
(LTC2624)
GND (Pin 1): Analog Ground.
REF LO (Pin 2): Reference Low. The voltage at this pin sets
the zero scale (ZS) voltage of all DACs. The voltage range
is 0 REF LO V
REF A, REF B, REF C, REF D (Pins 3, 6, 12, 15): Reference
Voltage Inputs for each DAC. REF x sets the full scale
voltage of the DACs. 0V REF x V
V
Outputs. The output range is from REF LO to REF x.

CS/LD (Pin 7): Serial Interface Chip Select/Load Input.
When CS/LD is low, SCK is enabled for shifting data on SDI
into the register. When CS/LD is taken high, SCK is
disabled and the specified command (see Table 1) is
executed.
SCK (Pin 8): Serial Interface Clock Input. CMOS and TTL
compatible.
SDI (Pin 9): Serial Interface Data Input. Data is applied to
SDI for transfer to the device at the rising edge of SCK. The
LTC2604/LTC2614/LTC2624 accepts input word lengths
of either 24 or 32 bits.
