Features and Benefits
- 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
- 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 and 20-Lead 4mm × 5mm QFN Packages
The LTC2600/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 and 20-lead 4mm × 5mm QFN 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 a simple SPI/MICROWIRE compatible 3-wire serial interface which can be operated at clock rates up to 50MHz. Daisychain capability and a hardware CLR function are included.
The LTC2600/LTC2610/LTC2620 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.

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.
