Product Details
The LTC2607/LTC2617/LTC2627 are dual 16-, 14- and 12-bit, 2.7V to 5.5V rail-to-rail voltage output DACs in a 12-lead DFN package. 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 and load regulation in single-supply, voltage-output DACs.
The parts use a 2-wire, I2C compatible serial interface. The LTC2607/LTC2617/LTC2627 operate in both the standard mode (clock rate of 100kHz) and the fast mode (clock rate of 400kHz). An asynchronous DAC update pin (LDAC) is also included.
The LTC2607/LTC2617/LTC2627 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 LTC2607-1/LTC2617-1/ LTC2627-1 to mid-scale. The voltage outputs stay at midscale until a valid write and update takes place.

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.
