• Manufacturer Part Number: LTC2600
• Description: (LTC2600 - LTC2620) 3V/5V Octal 12-bit Rail-to-rail DAC
• Manufacturer: Linear Technology

LTC2600/LTC2610/LTC2620
TYPICAL PERFOR A CE CHARACTERISTICS
LTC2620
PIN
GND (Pin 1): Analog Ground.
V
Voltage Outputs. The output range is 0 – V
REF (Pin 6): Reference Voltage Input. 0V V
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 dis-
abled and the specified command (see Table 1) is ex-
ecuted.
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

LTC2600 accepts input word lengths of either 24 or 32
bits.
SDO (Pin 10): Serial Interface Data Output. The serial
output of the shift register appears at the SDO pin. The data
transferred to the device via the SDI pin is delayed 32 SCK
rising edges before being output at the next falling edge.
This pin is used for daisy-chain operation.
CLR (Pin 11): Asynchronous Clear Input. A logic low at
this level-triggered input clears all registers and causes
the DAC voltage outputs to drop to 0V. CMOS and TTL
compatible.
