LTC2600/LTC2610/LTC2620 Octal 16-/14-/12-Bit Rail-to-Rail DACs in 16-Lead SSOP FEATURES DESCRIPTION n Smallest Pin-Compatible Octal DACs: The LTC 2600/LTC2610/LTC2620 are octal 16-, 14- and LTC2600: 16 Bits 12-bit, 2.5V-to-5.5V rail-to-rail voltage-output DACs in LTC2610: 14 Bits 16-lead narrow SSOP and 20-lead 4mm 5mm QFN LTC2620: 12 Bits packages. They have built-in high performance output n Guaranteed 16-Bit Monotonic Over Temperature buffers and are guaranteed monotonic. n Wide 2.5V to 5.5V Supply Range These parts establish new board-density benchmarks for n Low Power Operation: 250A per DAC at 3V 16- and 14-bit DACs and advance performance standards for n Individual Channel Power-Down to 1A, Max output drive, crosstalk and load regulation in single-supply, n Ultralow Crosstalk Between DACs (<10V) voltage-output multiples. n High Rail-to-Rail Output Drive (15mA, Min) n The parts use a simple SPI/MICROWIRE compatible 3-wire Double-Buffered Digital Inputs n serial interface which can be operated at clock rates up Pin-Compatible 10-/8-Bit Versions (LTC1660/LTC1665) n to 50MHz. Daisychain capability and a hardware CLR Tiny 16-Lead Narrow SSOP function are included. and 20-Lead 4mm 5mm QFN Packages The LTC2600/LTC2610/LTC2620 incorporate a power-on APPLICATIONS reset circuit. During power-up, the voltage outputs rise less n Mobile Communications than 10mV above zero-scale and after power-up, they stay n Process Control and Industrial Automation at zero-scale until a valid write and update take place. n Instrumentation L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks of Linear Technology Corporation.
