Overview

  • Smallest Pin-Compatible Quad DACs:
    • LTC2609: 16 Bits
    • LTC2619: 14 Bits
    • LTC2629: 12 Bits
  • Guaranteed Monotonic Over Temperature
  • Separate Reference Inputs
  • 27 Selectable Addresses
  • 400kHz I2C Interface
  • Wide 2.7V to 5.5V Supply Range
  • Low Power Operation: 250μA per DAC at 3V
  • Individual Channel Power Down to 1μA (Max)
  • High Rail-to-Rail Output Drive (±15mA, Min)
  • Ultralow Crosstalk Between DACs (5μV)
  • LTC2609/LTC2619/LTC2629: Power-On Reset to Zero-Scale
  • LTC2609-1/LTC2619-1/LTC2629-1: Power-On Reset to Mid-Scale
  • Tiny 16-Lead Narrow SSOP Package

The LTC2609/LTC2619/LTC2629 are quad 16-, 14- and 12- bit, 2.7V to 5.5V rail-to-rail voltage output DACs in a 16‑lead SSOP 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 DACs.

The parts use a 2-wire, I2C compatible serial interface. The LTC2609/LTC2619/LTC2629 operate in both the standard mode (clock rate of 100kHz) and the fast mode (clock rate of 400kHz).

The LTC2609/LTC2619/LTC2629 incorporate a power-on reset circuit. During power-up, the voltage outputs rise less than 10mV above zero-scale; after power-up, they stay at zero-scale until a valid write and update take place. The power-on reset circuit resets the LTC2609-1/LTC2619‑1/ LTC2629-1 to mid-scale. 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.
