LTC2600/LTC2610/LTC2620  
Octal 16-/14-/12-Bit  
Rail-to-Rail DACs in 16-Lead SSOP

DESCRIPTIO  
FEATURES  
The LTC®2600/LTC2610/LTC2620 are octal 16-, 14- and  
12-bit, 2.5V-to-5.5V rail-to-rail voltage-output DACs in  
16-lead narrow SSOP packages. They have built-in high  
performance output buffers and are guaranteed mono-  
tonic.  
Smallest Pin-Compatible Octal DACs:  
LTC2600: 16 Bits  
LTC2610: 14 Bits  
LTC2620: 12 Bits  
Guaranteed 16-Bit Monotonic Over Temperature  
Wide 2.5V to 5.5V Supply Range  
These parts establish new board-density benchmarks for  
16- and 14-bit DACs and advance performance standards  
for output drive, crosstalk and load regulation in single-  
supply, voltage-output multiples.  
The parts use a simple SPI/MICROWIRETM compatible  
3-wireserialinterfacewhichcanbeoperatedatclockrates  
up to 50MHz. Daisy-chain capability and a hardware CLR  
function are included.  
Low Power Operation: 250µA per DAC at 3V  
Individual Channel Power-Down to 1µA, Max  
Ultralow Crosstalk between DACs (<10µV)  
High Rail-to-Rail Output Drive (±15mA, Min)  
Double-Buffered Digital Inputs  
Pin-Compatible 10-/8-Bit Versions  
(LTC1660/LTC1665)  
Tiny 16-Lead Narrow SSOP Package  
U
The LTC2600/LTC2610/LTC2620 incorporate a power-on  
reset circuit. During power-up, the voltage outputs rise  
lessthan10mVabovezeroscale;andafterpower-up, they  
stay at zero scale until a valid write and update take place.
