LTC2606/LTC2616/LTC2626 16-/14-/12-Bit Rail-to-Rail DACs 2 with I C Interface Fea T Descrip T n Smallest Pin-Compatible Single DACs: The LTC 2606/LTC2616/LTC2626 are single 16-, 14- LTC2606: 16 Bits and 12-bit, 2.7V-to-5.5V rail-to-rail voltage output DACs LTC2616: 14 Bits in a 10-lead DFN package. They have built-in high per- LTC2626: 12 Bits formance output buffers and are guaranteed monotonic. n Guaranteed 16-Bit Monotonic Over Temperature These parts establish new board-density benchmarks for n 27 Selectable Addresses 16- and 14-bit DACs and advance performance standards 2 n 400kHz I C Interface for output drive and load regulation in single-supply, volt- n Wide 2.7V to 5.5V Supply Range age-output DACs. n Low Power Operation: 270A at 3V 2 n The parts use a 2-wire, I C compatible serial interface. The Power Down to 1A, Max n LTC2606/LTC2616/LTC2626 operate in both the standard High Rail-to-Rail Output Drive (15mA, Min) n mode (clock rate of 100kHz) and the fast mode (clock rate Double-Buffered Data Latches n of 400kHz). An asynchronous DAC update pin (LDAC) is Asynchronous DAC Update Pin n also included. LTC2606/LTC2616/LTC2626: Power-On Reset to Zero Scale The LTC2606/LTC2616/LTC2626 incorporate a power-on n LTC2606-1/LTC2616-1/LTC2626-1: Power-On Reset reset circuit. During power-up, the voltage outputs rise to Mid-Scale less than 10mV above zero scale and after power-up, n Tiny (3mm 3mm) 10-Lead DFN Package they stay at zero scale until a valid write and update take place. The power-on reset circuit resets the LTC2606-1/ a T LTC2616-1/LTC2626-1 to mid-scale. The voltage outputs stay at mid-scale until a valid write and update take place. n Mobile Communications L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks of Analog n Process Control and Industrial Automation Devices, Inc.
