The LTC2604/LTC2614/LTC2624 are quad 16-,14- and 12-bit 2.5V to 5.5V rail-to-rail voltage output DACs in 16-lead narrow SSOP packages. These parts have separate reference inputs for each DAC. They have built-in high performance output buffers and are guaranteed monotonic.These parts establish advanced performance standards for output drive, crosstalk and load regulation in single supply, voltage output multiples.The parts use a simple SPI/MICROWIRE compatible 3-wire serial interface which can be operated at clock rates up to 50MHz. Daisy-chain capability and a hardwareCLRfunction are included.The LTC2604/LTC2614/LTC2624 incorporate a poweron reset circuit. During power-up, the voltage outputs rise less than 10mV above zero scale; and after power-up, they stay at zero scale until a valid write and update take place. The power-on reset circuit resets the LTC2604-1/ LTC2614-1/LTC2624-1 to midscale. The voltage outputs stay at midscale until a valid write and update take place.ApplicationsMobile CommunicationsProcess Control and Industrial AutomationInstrumentationAutomatic Test Equipment
