LTC2605/LTC2615/LTC2625  
Octal 16-/14-/12-Bit  
Rail-to-Rail DACs in 16-Lead SSOP  
U
DESCRIPTIO  
FEATURES  
The LTC®2605/LTC2615/LTC2625 are octal 16-, 14-  
and 12-bit,2.7Vto5.5Vrail-to-railvoltage-outputDACsin  
16-lead narrow SSOP packages. They have built-in  
high performance output buffers and are guaranteed  
monotonic.  
Smallest Pin-Compatible Octal DACs:  
LTC2605: 16 Bits  
LTC2615: 14 Bits  
LTC2625: 12 Bits  
Guaranteed Monotonic Over Temperature  
400kHz I2C Interface  
Wide 2.7V 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 the 2-wire I2C compatible serial interface.  
The LTC2605/LTC2615/LTC2625 operate in both the  
standard mode (maximum clock rate of 100kHz) and the  
fast mode (maximum clock rate of 400kHz).  
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  
27 Selectable Addresses  
LTC2605/LTC2615/LTC2625: Power-On Reset to  
Zero Scale  
The LTC2605/LTC2615/LTC2625 incorporate a power-on  
LTC2605-1/LTC2615-1/LTC2625-1: Power-On Reset  
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.  
The power-on reset circuit resets the LTC2605-1/  
LTC2615-1/LTC2625-1 to midscale. The voltage output  
stays at midscale until a valid write and update  
takes place.
