LTC2630AISC6-LM10TRPBF

Single 12-/10-/8-Bit Rail-to-Rail DACs with Integrated Reference in SC70

Linear Technology 

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.
