LTC2601/LTC2611/LTC2621 16-/14-/12-Bit Rail-to-Rail DACs in 10-Lead DFN Features s DESCRIPTIO s s s s s s s s Smallest Pin-patible Single DACs: LTC2601: 16 Bits LTC2611: 14 Bits LTC2621: 12 Bits Guaranteed Monotonic Over Temperature Wide 2.5V to 5.5V Supply Range Low Power Operation: 300µA at 3V Power Down to 1µA, Max High Rail-to-Rail Output Drive (± 15m A, Min) Double-Buffered Data Latches Asynchronous DAC Update Pin Tiny (3mm × 3mm) 10-Lead DFN Package The LTC®2601/LTC2611/LTC2621 are single 16-, 14and 12-bit, 2.5V-to-5.5V rail-to-rail voltage output DACs in a 10-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 multiples. The parts use a simple SPI/MICROWIRETM patible 3-wire serial interface which can be operated at clock rates up to 50MHz. Daisy-chain capability, hardware CLR and asynchronous DAC update (LDAC) pins are included. The LTC2601/LTC2611/LTC2621 incorporate a power-on reset circuit. During power-up, the voltage outputs rise less than 10m V above zero scale; and after power-up, they stay at zero scale until a valid write and update take place. , LTC and LT are registered trademarks of Linear Technology Corporation.
