LTC2601/LTC2611/LTC2621 16-/14-/12-Bit Rail-to-Rail DACs in 10-Lead DFN FEATURES DESCRIPTION n Smallest Pin-Compatible Single DACs: The LTC 2601/LTC2611/LTC2621 are single 16-, 14- and LTC2601: 16 Bits 12-bit, 2.5V-to-5.5V rail-to-rail voltage output DACs in a LTC2611: 14 Bits 10-lead DFN package. They have built-in high performance LTC2621: 12 Bits output buffers and are guaranteed monotonic. n Guaranteed Monotonic Over Temperature These parts establish new board-density benchmarks for n Wide 2.5V to 5.5V Supply Range 16- and 14-bit DACs and advance performance standards n Low Power Operation: 300A at 3V for output drive and load regulation in single-supply, volt- n Power Down to 1A, Max age-output DACs. n High Rail-to-Rail Output Drive (15mA, Min) n The parts use a simple SPI/MICROWIRE compatible 3-wire Double-Buffered Data Latches n serial interface which can be operated at clock rates up to Asynchronous DAC Update Pin n 50MHz. Daisy-chain capability, hardware CLR and asyn- LTC2601-1/LTC2611-1/LTC2621-1: Power-On Reset chronous DAC update (LDAC) pins are included. to Midscale n Tiny (3mm 3mm) 10-Lead DFN Package The LTC2601/LTC2611/LTC2621 incorporate a power-on reset circuit. During power-up, the voltage outputs rise APPLICATIONS less than 10mV above zero scale until a valid write and update take place. The power-on reset circuit resets the n Mobile Communications LTC2601-1/LTC2611-1/LTC2621-1 to midscale. The volt- n Process Control and Industrial Automation age outputs stay at midscale until a valid write and update n Instrumentation take place. n Automatic Test Equipment L, LT, LTC and LTM are registered trademarks of Linear Technology Corporation.
