The 16-bit LTC2606 digital-to-analog converter (DAC) comes in a 3-mm2 DFN package with an I2C interface and 27 user-selectable slave addresses. As a result, many DACs can use the same bus while minimizing address conflicts with other components. Its guaranteed monotonic performance makes it useful for digital calibration, trim/adjust, and level-setting applications in a wide variety of products. The DAC's 2.7- to 5.5-V supply range draws a 270-µA operating current and 1-µA maximum shutdown current. Capacitive loads can be directly driven up to 1000 pF; current loads, up to 15 mA. Its 9-mV maximum output offset provides a low starting code voltage, and it's closer to 0 V than competing devices. Less output filtering is needed thanks to its 15-µV p-p 0.1- to 10-Hz noise. The LTC2606 powers up at zero-scale. The LTC2606-1 version powers up at midscale. Other variants include pin-compatible 14-bit and 12-bit DACs, which permit multiple price/performance options for one design. Pricing starts at $2.84 each in 1000-piece quantities.
