LTC2604/LTC2614/LTC2624  
Quad 16-Bit Rail-to-Rail DACs  
in 16-Lead SSOP  
U
FEATURES  
DESCRIPTIO  
The LTC®2604/LTC2614/LTC2624 are quad 16-,14- and  
12-bit 2.5V to 5.5V rail-to-rail voltage output DACs in  
16-lead narrow SSOP packages. These parts have sepa-  
rate reference inputs for each DAC. They have built-in  
high performance output buffers and are guaranteed  
monotonic.  
Smallest Pin Compatible Quad 16-Bit DAC:  
LTC2604: 16-Bits  
LTC2614: 14-Bits  
LTC2624: 12-Bits  
Guaranteed 16-Bit Monotonic Over Temperature  
Separate Reference Inputs for each DAC  
Wide 2.5V to 5.5V Supply Range  
These parts establish advanced performance standards  
for output drive, crosstalk and load regulation in single-  
supply, voltage output multiples.  
The parts use a simple SPI/MICROWIRETM compatible  
3-wire serial interface which can be operated at clock  
ratesupto50MHz.Daisy-chaincapabilityandahardware  
CLR function are included.  
Low Power Operation: 250µA per DAC at 3V  
Individual DAC Power-Down to 1µA, Max  
Ultralow Crosstalk Between DACs (<5µV)  
High Rail-to-Rail Output Drive (±15mA)  
Double Buffered Digital Inputs  
16-Lead Narrow SSOP Package  
U
APPLICATIO S  
The LTC2604/LTC2614/LTC2624 incorporate a power-  
on reset circuit. During power-up, the voltage outputs  
rise less than 10mV above zero scale; and after power-  
up, they stay at zero scale until a valid write and update  
take place.
