LTC2602/LTC2612/LTC2622
PIN FUNCTIONS
CS/LD (Pin 1): 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 dis-
abled and the specified command (see Table 1) is ex-
ecuted.
SCK (Pin 2): Serial Interface Clock Input. CMOS and TTL
compatible.
SDI (Pin 3): Serial Interface Data Input. Data is applied to
SDI for transfer to the device at the rising edge of SCK. The
LTC2602/LTC2612/LTC2622 accept input word lengths
of either 24 or 32 bits.
REF (Pin 4): Reference Voltage Input. 0V ≤ VREF ≤ VCC.
VOUT B and VOUT A (Pins 5 and 8): DAC Analog Voltage
Outputs. The output range is 0 – VREF.
VCC (Pin 6): Supply Voltage Input. 2.5V ≤ VCC ≤ 5.5V.
GND (Pin 7): Analog Ground.
