Overview

  • Smallest Pin Compatible Quad 16-Bit DAC:
    • LTC2604: 16-Bits
    • LTC2614: 14-Bits
    • LTC2624: 12-Bits
  • Guaranteed 16-Bit Monotonic Over Temperature
  • Separate Reference Inputs for each DAC
  • Wide 2.5V to 5.5V Supply Range
  • Low Power Operation: 250µA per DAC at 3V
  • Individual DAC Power-Down to 1µA, Max
  • Ultralow Crosstalk Between DACs (<5µV)
  • High Rail-to-Rail Output Drive (±15mA)
  • Double Buffered Digital Inputs
  • LTC2604-1/LTC2614-1/LTC2624-1: Power-On Reset to Midscale
  • 16-Lead Narrow SSOP Package

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 hardware CLR function 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.

Tools & Simulations

Precision DAC Error Budget Tool

The Precision DAC Error Budget Tool is a web application that calculates the DC Accuracy of precision DAC signal chains. It shows how the static errors accumulate throughout your signal chain to quickly evaluate the design tradeoffs. Calculations include the DC errors introduced by Voltage References, Operation Amplifiers and Precision DACs.
