LTC2604/LTC2614/LTC2624 Quad 16-Bit Rail-to-Rail DACs in 16-Lead SSOP FEATURES DESCRIPTION n Smallest Pin Compatible Quad 16-Bit DAC: The LTC 2604/LTC2614/LTC2624 are quad 16-,14- and LTC2604: 16-Bits 12-bit 2.5V to 5.5V rail-to-rail voltage output DACs in LTC2614: 14-Bits 16-lead narrow SSOP packages. These parts have separate LTC2624: 12-Bits reference inputs for each DAC. They have built-in high per- n Guaranteed 16-Bit Monotonic Over Temperature formance output buffers and are guaranteed monotonic. n Separate Reference Inputs for each DAC These parts establish advanced performance standards n Wide 2.5V to 5.5V Supply Range for output drive, crosstalk and load regulation in single- n Low Power Operation: 250A per DAC at 3V supply, voltage output multiples. n Individual DAC Power-Down to 1A, Max n The parts use a simple SPI/MICROWIRE compatible Ultralow Crosstalk Between DACs (<5V) n 3-wire serial interface which can be operated at clock rates High Rail-to-Rail Output Drive (15mA) n up to 50MHz. Daisy-chain capability and a hardware CLR Double Buffered Digital Inputs n function are included. LTC2604-1/LTC2614-1/LTC2624-1: Power-On Reset to Midscale The LTC2604/LTC2614/LTC2624 incorporate a power-on n 16-Lead Narrow SSOP Package reset circuit. During power-up, the voltage outputs rise less than 10mV above zero scale and after power-up, they stay APPLICATIONS at zero scale until a valid write and update take place. The power-on reset circuit resets the LTC2604-1/LTC2614-1 n Mobile Communications /LTC2624-1 to midscale. The voltage outputs stay at mid- n Process Control and Industrial Automation scale until a valid write and update take place. n Instrumentation L, LT, LTC and LTM are registered trademarks of Linear Technology Corporation. n Automatic Test Equipment All other trademarks are the property of their respective owners.
