LTC2630
PIN FUNCTIONS
⎯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 specified 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.
VCC (Pin 4): Supply Voltage Input. 2.7V ≤ VCC ≤ 5.5V
(LTC2630-L) or 4.5V ≤ VCC ≤ 5.5V (LTC2630-H). Also
used as the reference input when the part is programmed
to operate in supply as reference mode. Bypass to GND
with a 0.1μF capacitor.
GND (Pin 5): Ground.
VOUT (Pin 6): DAC Analog Voltage Output.
