Features and Benefits
- Smallest Pin-Compatible Octal DACs:

- Wide 2.7V to 5.5V Supply Range
- Low Power Operation: 250µA per DAC at 3V
- Individual Channel Power-Down to 1µA (Max)
- Ultralow Crosstalk Between DACs (<10µV)

- 27 Selectable Addresses
- LTC2605/LTC2615/LTC2625: Power-On Reset to Zero-Scale
- LTC2605-1/LTC2615-1/LTC2625-1: Power-On Reset to Mid-scale
- Tiny 16-Lead Narrow SSOP Package
The LTC2605/LTC2615/LTC2625 are octal 16-, 14- and 12-bit, 2.7V 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 monotonic.
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).
The LTC2605/LTC2615/LTC2625 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. The power-on reset circuit resets the LTC2605-1/LTC2615-1/LTC2625-1 to mid-scale. The voltage output stays at mid-scale until a valid write and update takes place.

Product Lifecycle Production
At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
Tools & Simulations
Linduino is Analog Devices’ Arduino compatible system for developing and distributing firmware libraries and example code for our integrated circuits. Each Linduino-supported product includes an example main program, defined in the LTSketchbook/Part Number folder and driver code, defined in the LTSketchbook/libraries folder.
Precision DAC Error Budget Tool
The Precision DAC Error Budget Tool is a web application that calculates the DC Accuracy of precision DAC signal chains. It shows how the static errors accumulate throughout your signal chain to quickly evaluate the design tradeoffs. Calculations include the DC errors introduced by Voltage References, Operation Amplifiers and Precision DACs.
ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. "Zero defects" for shipped products is always our goal.
