PIN FUNCTIONS

GND (Pin 1): Analog Ground.

VOUT A to VOUT H (Pins 2-5 and 12-15): DAC Analog

Voltage Outputs. The output range is 0 – VREF.

REF (Pin 6): Reference Voltage Input. 0V

≤ VREF ≤ VCC.

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, LTC2610 and LTC2620 accept 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.

VCC (Pin 16): Supply Voltage Input. 2.5V ≤ VCC ≤ 5.5V.
